About the company

We raised $5.1M to build agents that operate as fully autonomous founders. Our backers include Matt Schlicht (founder of Moltbook), the founders of Crunchbase and Republic, and VCs including Draper, Precursor, and Liquid2.

We're working at the frontier of autonomous systems, building agents that don't just chat, but run entire businesses.

Our system identifies business opportunities through market signals, validates ideas with live ad tests, builds and launches software products, and brings in human experts wherever agents fall short. That loop already runs end to end: from idea to launched product to first revenue.

Over the next 12 months, our focus is on reliability, throughput, and self-improvement, making every launch better than the last.

About the role

We're looking for a hands-on AI Engineer to take ownership of the architecture and development of our autonomous agent system.

You'll lead the technical direction of the platform, building multi-agent orchestration systems, self-improving agent harnesses, and AI-powered backend services. This is a highly technical leadership role that combines architectural decision-making with hands-on engineering.

You'll be expected to ship production code, make key technical decisions, improve agent behavior in production, and help establish the engineering standards as the company scales.

Responsibilities

  • Own the system architecture and make key technical decisions across the platform.

  • Design and build multi-agent systems and orchestration infrastructure that take products from idea to launch.

  • Develop self-improving agent harnesses, including feedback loops, evaluation systems, and memory.

  • Build and maintain AI-powered backend services on top of LLM APIs such as Anthropic, OpenAI, and Gemini.

  • Write production code, particularly around agent runtime and orchestration.

  • Debug and improve AI behavior in production through prompt engineering, structured outputs, retries, and fallbacks.

  • Break down complex technical challenges into actionable milestones and prioritize the engineering roadmap.

  • Establish engineering standards around code reviews, testing, observability, and release processes.

  • Lead and support the engineering team while remaining deeply involved in implementation.

Requirements

  • 4+ years of professional software engineering experience.

  • Previous technical leadership experience at an early-stage company (Founding Engineer, Tech Lead, Head of Engineering, or similar).

  • Hands-on experience building and shipping multi-agent systems and orchestration frameworks to production.

  • Experience developing self-improving or self-evolving agent harnesses.

  • Strong backend engineering skills, including designing and maintaining APIs, services, and data flows.

  • Experience working with LLM-based systems, including prompt engineering, model configuration, structured outputs, embeddings, retrieval, and evaluation.

  • Daily hands-on experience with AI coding agents such as Claude Code, Cursor, OpenAI Codex, or similar tools. You should know how to delegate work to agents, review their output, and verify what they build.

Nice to have

  • Strong TypeScript and Node.js experience.

  • Experience with Vercel AI SDK, Claude Agent SDK, or building custom agent runtimes.

  • Experience with PostgreSQL, Supabase, and pgvector.

  • Familiarity with background job systems such as Inngest or Pub/Sub.

  • Experience with Zod, Vitest, and GCP Cloud Run.

  • Experience growing or restructuring distributed engineering teams.

  • Interest in AI evaluation, safety, and observability.

Tech & Remote Glossary

Stop getting lost in interviews and job descriptions

The job market, especially within tech and global companies, has developed its own dialect. Not understanding these acronyms can make you lose valuable opportunities or poorly negotiate your contract. To end this problem, we created the Definitive Glossary for the Remote Professional.

🏢 Work Models & Routine

Async (Asynchronous Work)
A communication model where responses don't need to be immediate. Instead of back-to-back meetings, the team relies on well-structured documents, threads, and messages. It's the gold standard for global companies spanning multiple time zones.
Sync (Synchronous Work)
The opposite of Async. It requires the team to be online and available at the same time for meetings, live chats, and real-time collaboration.
Daily / Stand-up
A quick daily meeting (usually 15 minutes) common in Agile (Scrum) methodologies. The team answers three questions: What did I do yesterday? What will I do today? Are there any blockers?
All-Hands / Town Hall
A company-wide meeting involving all employees. Usually led by the founders (C-Levels) to present results, new goals, and answer team questions.
1:1 (One-on-One)
A recurring individual meeting between a professional and their direct manager. It is used for career alignment, feedback, and problem-solving, not just for project status updates.

💰 Contracts, Benefits & Compensation

PTO (Paid Time Off)
Instead of strict, categorized leave policies, modern US companies usually offer a flexible pool of days (e.g., 20 days of PTO, or even "Unlimited PTO") that you can use for vacations, sick days, or personal matters, while receiving your regular compensation.
Equity / Stock Options
Company ownership. The startup offers you the right to buy shares at a heavily discounted strike price in the future. If the company grows, goes public, or is acquired, these shares can be highly lucrative.
Vesting (Vesting Schedule)
The rule that controls your Equity. It usually lasts 4 years. You don't get all the shares on day one; you "earn" them gradually as you stay with the company. A "1-year Cliff" means you must stay for at least one year to receive your first batch of shares.
RSUs (Restricted Stock Units)
Unlike Stock Options (where you have the right to buy the stock), RSUs are actual shares the company grants you as a bonus or part of your compensation package, following a strict Vesting schedule.
Independent Contractor (1099 / B2B)
The most common international hiring model for global talent working for US companies. You act as a service provider (business-to-business), receiving the gross salary (often six-figure compensation) without standard local payroll tax deductions at the source.

🤖 Recruitment & Hiring Process

ATS (Applicant Tracking System)
The "robot" that reads your resume. Software like Greenhouse, Ashby, and Workday are used to filter candidates by keywords before a human even looks at the document. (Pro tip: this is why your resume must be clean, semantic, and have the right keywords).
JD (Job Description)
The document that lists the responsibilities, technical requirements, and benefits of the open position.
Cultural Fit
The interview stage that evaluates if your core values, communication style, and worldview align with the company's culture. This is the ultimate test of your Soft Skills.
Onboarding
The integration process. It's the period of your first few weeks at the company, where you get your access credentials, learn about the culture, study the internal documentation, and understand how the product works.

🚀 How to use this to your advantage?

The secret isn't just knowing what these acronyms mean, but using them actively. If during an interview for a premium tech role you ask, "How does your PTO policy and Vesting schedule work?", the recruiter will immediately perceive you as a high-level professional, familiar with the global market standards.

The remote job market requires preparation. And having the right vocabulary is the first big step to securing six-figure proposals and standing out among thousands of applicants.

The New Paradigm of Digital Marketing and Social Media

The New Paradigm of Digital Marketing and Social Media: Impact, Opportunities, and the Future of the Market

By Mondywork Team | 6-minute read

The Evolution: From "Just Posting" to True Revenue Engines

There was a time when digital marketing was viewed as a secondary department, heavily focused on vanity metrics like likes and follower counts. That era is officially over. In today's global market, Digital Marketing and Social Media Management are the beating heart of customer acquisition, acting as literal Revenue Engines.

Top-tier US startups, unicorns, and global B2B/B2C enterprises have realized that consumer attention is the most expensive asset on the internet. It's no longer just about creativity; it's about merging authentic communication with ruthless data analysis and Artificial Intelligence integrations.

How Does This Market Impact Global Companies?

The impact of modern marketing on the corporate world is absolute. According to the HubSpot State of Marketing report, companies that closely align their digital strategies with sales see a 20% higher revenue growth.

  • CAC Reduction and LTV Focus: Companies rely on marketing professionals to lower Customer Acquisition Cost (CAC) through organic traffic and social media, while simultaneously increasing Lifetime Value (LTV) through retention strategies.
  • Community-Led Growth: Brands don't just want consumers anymore; they want raving fans. Social media has evolved into a community-building channel, where engagement breeds brand advocates who buy repeatedly.
  • Global and Borderless Presence: Digital marketing has shattered geographical borders. A startup in Silicon Valley can easily scale its sales in Europe using campaigns managed by a strategist based in Brazil, Portugal, or anywhere else, working 100% remote.

The 2026 Landscape: What Do Companies Expect?

The digital marketing job market has never been more technical and demanding. The era of the "jack-of-all-trades" generalist is making way for hyper-focused experts and strategists with a systemic vision—the highly sought-after "T-Shaped" professionals.

"Marketing has transitioned from an art based purely on intuition to a science driven by data, predictability, and hyper-segmentation."
— eMarketer Digital Trends

The barrier to entry has risen significantly due to the integration of Artificial Intelligence. Tools that generate copy or images in seconds (like ChatGPT and Midjourney) haven't replaced the professional; they've raised the bar. The market now seeks talent who can "pilot" these AIs to craft strategies, automate workflows using tools like n8n or Zapier, and analyze Business Intelligence (BI) dashboards in Looker Studio.

Golden Opportunities: The Hottest Roles

Highly qualified professionals are being fiercely fought over, especially on platforms like Mondywork, where international companies seek remote talent offering six-figure compensation and global remote flexibility. The areas with the highest demand include:

  1. Growth Marketer / Hacker: The professional focused on rapid experimentation across the marketing funnel (Pirate Metrics - AARRR). They blend marketing, data analysis, and a bit of product engineering to find scalable growth levers.
  2. Performance Manager (Paid Media): The traditional traffic manager has evolved. Today, this professional manages multi-million dollar budgets across Google Ads, Meta Ads, and LinkedIn Ads (essential for B2B), with an absolute focus on ROAS (Return on Ad Spend).
  3. Social Media Strategist & Community Manager: Going far beyond scheduling posts, this talent understands internet culture, dominates short-form formats (TikTok, Reels, Shorts), and knows how to convert a social audience into qualified leads within the company's sales funnel.
  4. SEO & Content Architect: With shifting search algorithms and the impact of AI (Search Generative Experience), the SEO professional who masters search intent, information architecture, and Core Web Vitals is indispensable for long-term organic acquisition.
  5. Marketing Operations (Marketing Ops): The architect behind the curtain. They manage CRMs (Salesforce, HubSpot), email automations, and ensure the entire marketing data infrastructure is flawless.

Is It Worth Entering or Transitioning into This Field?

Absolutely. If you are an analytical, curious professional who understands human behavior and isn't afraid of data spreadsheets, digital marketing offers one of the most promising and flexible career paths in the modern world.

To stand out in rigorous international recruitment systems (ATS like Greenhouse and Ashby), it is crucial that your resume and portfolio showcase real results. Forget generic descriptions; US tech recruiters and Heads of Marketing want to read hard metrics: "Increased organic traffic by 150% in 6 months" or "Managed $500k in ad spend while maintaining CAC 20% below target".

The global market is vast, decentralized, and pays incredibly well for those who know how to turn clicks and views into predictable revenue.
