Fullstack Engineer — Lazo

Lazo is building the AI-powered operating system for modern startups — automating everything founders shouldn't have to think about: finance, legal, tax, payroll, and fundraising, all under one roof. You'll have massive ownership and work directly with founders.

The role

The Software Engineer will design, develop, and maintain robust software solutions for the Lazo Platform. You will work across a modern TypeScript and Python stack, building product features that help startup founders manage incorporation, compliance, and accountability in a high-trust, regulated domain.

As part of the product team, you will translate business requirements into scalable technical solutions that drive product growth and improve user experience. You'll collaborate closely with product management, design, and engineering to ship high-quality software in a fast-paced startup environment.

This position reports to the Chief Technology Officer.

Tech stack

Lazo is built as an Nx polyglot monorepo (pnpm workspaces) deployed to Container Apps:

  • Frontend — Next.js 16 (App Router, React Server Components) + React 19 + TypeScript, organized with Feature-Sliced Design (FSD).

  • Backend — FastAPI (Python 3.11) with async SQLAlchemy 2.0 over PostgreSQL.

  • Data — PostgreSQL per service; Prisma and SQLAlchemy as the ORM seams.

  • Testing — BDD/Gherkin across layers: Vitest + vitest-cucumber (TS), pytest-bdd + httpx (FastAPI), Playwright (e2e).

  • Infra & delivery — GitHub Actions CI/CD, Docker, Container Apps, Key Vault, OIDC federated auth.

Lazo handles sensitive data — SSNs, EINs, passports, bank accounts, cap tables, tax filings. Security, data integrity, and auditability are the top priorities, ahead of availability, privacy/compliance (SOC 2, GDPR, CCPA), testability, and maintainability.

What you'll do

  • Take specs and features all the way to production — backend, frontend, tests, deploy.

  • Write Gherkin tests before writing code. A claim that isn't backed by a test doesn't exist.

  • Use AI tools (Claude, Claude Code, MCP) as part of your daily workflow, not as an experiment.

  • Contribute to technical decisions with conviction: propose, question, improve.

  • Handle sensitive data (SSNs, EINs, bank accounts, cap tables) with the seriousness it demands — security, tenant isolation, auditability, mask-on-read.

  • Collaborate directly with the team to understand the problem before solving it.

What we're looking for

Hard skills:

  • Solid fullstack experience — backend and frontend in production environments.

  • Strong command of React / Next.js (App Router, RSC) and TypeScript.

  • Familiarity with async, event-driven architectures and RESTful API design.

  • Comfort with PostgreSQL and ORMs (SQLAlchemy, Prisma, or similar).

  • Experience writing tests — unit, integration, and ideally BDD/Gherkin.

  • Python knowledge at an architectural level (not necessarily years of hands-on production experience).

  • Exposure to cloud environments (Azure, AWS, or GCP) and CI/CD pipelines.

Mindset:

  • Background in high-stakes environments — banking, fintech, or startups where systems have to work, no excuses.

  • Actively curious: you try new things before anyone asks you to.

  • Strong fundamentals mindset: you're not interested in the quick hack that blows up in production.

  • Genuinely AI-first: Claude Code, MCP, AI-assisted workflows are tools you already use or pick up fast.

  • Able to work from specs as input and code as output — Specs Driven Development.

  • Advanced English.

  • 100% remote

  • Flexible work culture — we measure by results

  • Week off between Christmas and New Year's Eve

  • Health benefits

  • Birthday day off

Expert Tip

Generative Design and AI as a Co-pilot

If the last decade in digital design was defined by mobile standardization and UX/UI becoming the core of product development, 2026 marks the dawn of a new era. We are no longer designing just for flat glass screens; we are building intelligent ecosystems, three-dimensional environments, and autonomous algorithms.

For designers looking to stand out and secure the best six-figure remote opportunities in the US tech market, understanding where the industry is heading is no longer a "nice-to-have" differential—it's a matter of professional survival. Below, we break down the four major trends that will dictate hiring and compensation in the 2026 design landscape.

1. Generative Design and AI as a Co-pilot (Not a Replacement)

The fear of Artificial Intelligence replacing designers is officially in the past. In 2026, generative AI is deeply and natively integrated into industry-standard tools like Figma, Adobe, and Framer. The most valued skill by top-tier tech companies is no longer speed in aligning components, but rather algorithmic art direction and prompt design.

  • UI Automation: Wireframing, component variations, and complex design systems can now be generated with a few text prompts.
  • The Designer's New Role: Professionals are shifting from operational executors to curators and strategists, ensuring that AI-generated outputs align with user psychology and core business objectives.

2. Spatial Design and Spatial Computing

With the maturation of mixed reality devices (such as the Apple Vision Pro and Meta's advanced lineups), Spatial Design has evolved from an experimental niche to a mandatory department in Big Tech and forward-thinking startups.

Designing for spatial computing requires a complete paradigm shift: designers must understand Z-axis depth, visual ergonomics, spatial audio, and interactions based on eye-tracking and hand gestures. Roles like AR/VR Product Designer and 3D Interaction Designer are seeing an exponential jump in job listings, often paired with premium compensation packages.

3. Conversation Design and Invisible Interfaces (Zero-UI)

Driven by the omnipresence of Large Language Models (LLMs), the way users interact with systems has fundamentally changed. In 2026, many of the best interfaces don't rely on buttons or hamburger menus; they are conversational. UX Writing and Conversation Design have taken center stage.

  • The Challenge: How do you design the "personality" and flow of a virtual assistant so it feels natural, empathetic, and on-brand, rather than like a rigid robot?
  • The Opportunity: Designers who know how to map complex decision trees, create logical flows for voice and text, and train the empathy of AI models are being heavily scouted by top US startups.

4. Digital Sustainability and Eco-Design

The ESG (Environmental, Social, and Governance) agenda has finally reached the product design tables. The internet consumes a massive amount of energy, and in 2026, tech companies are being strictly held accountable for their digital carbon footprint.

Enter the demand for Digital Eco-Design. This involves creating lighter interfaces, optimizing user flows to reduce screen time (saving battery life and server processing power), and adopting color palettes and assets (like SVGs instead of heavy raster images) that require less energy to render. Being a sustainable designer has become a powerful B2B selling point for agencies and freelancers alike.

Conclusion: The Evolution of Talent

The 2026 design market is highly rewarding for those who embrace complexity. The barrier to entry for making "pretty screens" has dropped significantly, but the demand for professionals who can solve intricate business problems through empathy, strategy, and the mastery of new technologies has never been higher.
