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.

Expert Tip

Landing Top-Tier Traffic Analyst and SEO Roles

The New Era of Performance Marketing

The digital marketing landscape has undergone a radical transformation in recent years. The era of the "button pusher" who merely launched Meta Ads campaigns or stuffed keywords into WordPress is officially over. Today, companies—especially top-tier US startups and global tech corporations offering six-figure compensations—are looking for analytical, Growth-focused, and highly Data-Driven professionals.

Whether managing multi-million dollar paid media budgets or optimizing site architecture for the new AI-driven search engines, the Traffic and SEO Analyst has become the engine of predictable revenue for tech companies worldwide.

1. Technical SEO and the AI Revolution (SGE)

With Google's introduction of the Search Generative Experience (SGE), SEO is no longer just about backlinks and search volume. It now requires a deep understanding of search intent and topical authority.

What Tech Recruiters are looking for:

  • Technical SEO Mastery: The ability to analyze Core Web Vitals, manage Crawl Budgets, and optimize JavaScript rendering (a critical factor for modern frameworks like React and Next.js).
  • Advanced Data Analysis: Fluency in enterprise tools such as Screaming Frog, Semrush, Ahrefs, and Google Search Console.
  • Focus on E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness. Understanding how to structure content so that Google's algorithm recognizes it as a reliable primary source.
"Modern SEO success requires you to stop optimizing for algorithms and start optimizing for the user journey, using technical data to remove any friction along the way." — Google Search Central Guidelines

2. Paid Traffic: From Operational to Strategic

In the realm of paid media (Google Ads, Meta Ads, LinkedIn Ads, TikTok Ads), platform automation handles most of the bidding work (Smart Bidding). The modern candidate's competitive edge lies in acquisition strategy and financial viability analysis.

Metrics you must master for your interviews:

  1. CAC (Customer Acquisition Cost): Moving beyond Cost Per Click (CPC). Understanding exactly how much it costs to acquire a paying user.
  2. LTV (Lifetime Value): Knowing how to cross-reference acquisition costs with the value a customer brings to the company over time (LTV:CAC ratio).
  3. ROAS vs. ROI: Grasping the crucial difference between the direct return on ad spend (ROAS) and the actual return on investment for the entire business (ROI).
  4. Server-Side Tracking: With the deprecation of third-party cookies, mastering the Conversions API and Google Tag Manager (GTM) Server-Side is a massive senior requirement.

3. Building an Unbeatable Portfolio

In the global remote market, degrees matter far less than proven results. Your portfolio shouldn't just be a resume; it should be a comprehensive document of Case Studies.

Structure your cases using the STAR method:

  • Situation: What was the baseline? E.g., "The e-commerce brand was burning $10k/month with a 1.2 ROAS."
  • Task: What was the goal? E.g., "Reduce CPA by 30% and increase non-branded organic traffic."
  • Action: What did YOU do technically? E.g., "Audited GTM, restructured PMax campaigns, and applied Schema markup in the HTML."
  • Result: The numerical impact. E.g., "Scaled ROAS to 3.8 and grew organic traffic by 45% in 3 months."

4. Certifications That Actually Open Doors

If you want to bypass strict Applicant Tracking Systems (ATS) like Greenhouse or Workday, ensure your LinkedIn and resume feature official certifications issued by the tech platforms themselves:

References and Must-Reads

To stay relevant in a market that changes weekly, we highly recommend following these official sources:

  1. Official Google Search Central Documentation.
  2. Annual State of Marketing Reports from HubSpot and Semrush.
  3. Technical articles focused on Data-Driven Marketing from the Harvard Business Review.
