• Exact application requirements and deadlines: The posting on WeWorkRemotely lists title and link; startups typically require a resume, GitHub/portfolio, and a cover note; some ask for examples of production code or links to deployed projects. There is no public global application deadline—apply as soon as possible and tailor materials to the posting. Confirm the live posting for any application form fields.
• Step‑by‑step application process (typical for this role):

1. Submit resume, tailored cover note, and links (GitHub, personal site, LinkedIn) via the job posting form.
2. Recruiter screen (30–45 min): discuss background, interest, compensation range, and basic culture fit.
3. Technical screen (45–60 min): live coding or take‑home challenge focusing on JS/React/Node.
4. Take‑home assignment or project review (1–3 days to complete) for product/engineering fit—implement a small feature or API endpoint and include tests.
5. Onsite loop (remote): 2–4 interviews

• system design for mid‑level (small‑scale), frontend deep dive (React), backend/API/DB, and a cross‑functional/product interview.

6. Reference checks and offer.

• Common interview questions for this role/company:
• Frontend: “Explain how you structure state in a React app with complex forms.”; “How do you optimize React rendering and avoid unnecessary re‑renders?”
• Backend: “Design an API endpoint for [feature] with authentication, validation, and rate limiting.”; “How would you structure database models for projects, users, and proposals in a freelance marketplace?”
• Full‑stack: “Walk through implementing a feature end‑to‑end (UI, API, DB, deployment).”
• Product/behavioral: “Tell me about a time you shipped a feature that improved metrics.”; “How do you handle ambiguous requirements?”
• Culture: “Describe working remotely at scale—how do you communicate and keep alignment?”
• Assessment centers or case studies: Many startups use take‑home coding tasks or small case studies simulating real product work (e.g., build a minimal client profile page with CRUD); be prepared to submit code with tests and a README explaining tradeoffs.
• What makes a standout candidate:
• Production examples: live projects, contributions to open source, or shipped features are more persuasive than theoretical coding problems.
• Clear product thinking: show measured impact (metrics), tradeoff reasoning, and user empathy.
• Strong testing and engineering hygiene: automated tests, CI/CD, and code quality.
• Asynchronous communication skills and remote collaboration experience.
• Domain knowledge of freelance marketplaces/payments is a plus. Insider Tips (practical, company‑specific)
• Company-specific interview tips and what they value:
• Emphasize end‑to‑end ownership—describe features you’ve delivered from idea to production.
• Show awareness of user needs for independent workers (billing, proposals, contracts, profile discoverability).
• Demonstrate remote collaboration skills (documenting decisions, async PR descriptions, time‑zone coordination).
• Technical skills vs soft skills priorities:
• Both matter: technical competency (React/Node, testing, deployable code) is required; soft skills (communication, ownership, ship mentality) often determine hiring decisions at startups.
• Industry knowledge you should demonstrate:
• Basics of freelancer marketplaces (matching, discovery, fees, payments, disputes).
• Security and privacy concerns around payments and profiles.
• Questions to ask interviewers to show genuine interest:
• “Which product metric does the engineering team most influence right now?”
• “What’s a recent engineering tradeoff you made and why?”
• “How do you measure success for a mid‑level engineer in their first 6 months?”
• “What ownership will I have over product areas and incident response?”
• Red flags to avoid in applications/interviews:
• Generic resumes and cover letters that don’t reference Contra or marketplace experience.
• Overstated experience without concrete examples of shipped work.
• Poor async communication in follow‑up messages (typos, lack of structure). Practical Information (compensation, benefits, logistics)
• Salary/stipend ranges for this level: For remote mid‑level full‑stack engineers at US/global startups in 2024–2025, typical base salary bands are approximately:
• US (mid‑level): $100k–$150k base, plus equity and benefits—ranges depend on location and funding stage.
• International adjustments: salaries may be regionally adjusted for fully remote roles. (These are market estimates—confirm exact range in the job post or recruiter discussion.)
• Benefits package details: Startups like Contra typically offer equity (options), health insurance stipends (or group plans for US hires), paid time off, parental leave policies, and learning stipends—confirm specifics in the offer.
• Start dates and program duration: This is a standard hire (start date flexible per candidate and team needs); no fixed “program duration.” Onboarding is usually 2–8 weeks ramp, and role is ongoing.
• Networking opportunities and alumni connections: Working at a marketplace scale gives exposure to product, design, growth, and possible external speaking/meetup opportunities; Contra’s alumni and network in the freelance ecosystem can be valuable—ask recruiters about alumni channels and community programs. Actionable checklist for applicants (18–25 students and recent grads)
• If you’re younger (18–25) and applying for a mid‑level role, be realistic about level: mid‑level typically requires 2–4 years of production experience; consider internships, junior roles, or capstone projects if you lack full‑time experience.
• Build a portfolio with:
• 2–3 full‑stack projects deployed publicly (link to live app + GitHub).
• A clear README explaining your architecture, design decisions, tests, and deployment steps.
• One project that simulates marketplace features (profiles, proposals, messaging or payments mock).
• Prepare for interviews:
• Practice a timed take‑home assignment and be ready to explain tradeoffs.
• Review React performance hooks, Node.js API patterns, SQL schema design, and basic system design for small services.
• Prepare STAR stories that show ownership, shipping, and remote collaboration.
