We are looking for a Senior Node.js Developer
This role is fully remote, we accept candidates from anywhere around the globe, given that candidates are within an acceptable time-zone difference to UTC+4 (at least 5 hours of overlap)
Salary: up to 35 EUR/h (on a B2B)
Start date: September 2026
Duration: till 31.12.2026
Engagement: Full-time
Requirements
We are looking for Software Engineers with:
(roughly 5-8 years of experience), able to do without supervision:
Design services using well-understood patterns for iterative, autonomous development and future scaling - bounded contexts, deliberately minimizing cross-service dependencies for resilience.
Design for expected peak load rather than average, know the limits of the services and third-party dependencies a feature relies on, and validate those limits by testing rather than by reasoning alone.
Build components other teams can adopt, with documentation and a migration path - treating other teams as consumers, not recipients.
Diagnose issues across service boundaries, not only within a single service.
Write architecture decision records that capture why a decision was made, not only what was decided.
Design with abuse in mind by default — rate limits, velocity checks, idempotency - and raise risk trade-offs during design and review rather than after launch.
Also required:
- Reading and being able to explain every line of AI-generated code you ship - no merging what you can't explain.
- Testing that actually covers edge and failure cases, not just happy-path coverage.
- Working command of OWASP Top 10 and secure-by-default habits (secrets management, input validation, data handling).
- Strong written English - most collaboration happens asynchronously via RFCs and reviews.
- A collaborative style: you bring options with trade-offs, argue with reasoning rather than seniority, and can lose a technical argument gracefully.
Responsibilities:
This isn't a "managed team" gig and it isn't ticket-closing work. The client has strong internal engineers already — what they're bringing in is deep system design judgement: help deciding what to build, where the boundaries sit, what breaks first under load, and what's expensive to change a year from now. You'll pair directly with their engineering manager and team, inside their existing rituals (planning, standups, design review), and your designs go into production — not into a slide deck.
What you'd actually be doing:
- Digging into an existing multi-product architecture to understand why it looks the way it does before proposing changes.
- Contributing to an honest, evidence-based assessment of code and design quality — correctness on money/stock paths, security posture, coupling between product lines.
- Writing RFCs and ADRs for new and evolving systems: assumptions, failure modes, capacity, security made explicit.
- Working on extend-vs-rebuild decisions with the migration path built in from day one — not bolted on after.
- Working with real constraints: multi-currency payments (IQD/AED/SAR), fraud and abuse exposure, PCI DSS scope, third-party supplier integrations, and traffic spikes up to 65x baseline.
Benefits
- 100% remote work;
- work with an experienced team of developers and continuous development of your hard and soft skills;
- long-term collaboration on challenging products
