Quick Facts

• Role: Staff Node.js Developer (Architecture)

• Work model: Fully remote

• Time zone: At least 5 hours of overlap with UTC+4

• Contract: September 2026 to 31.12.2026

• Engagement: Full-time

• Pay: Up to 42 EUR/h (B2B)

Description

Staff Node.js Developer (Architecture) needed for deep system design and architecture judgment in a multi-product architecture. You will work as a technical peer with existing Staff engineers and engineering managers, and your RFC/ADR-driven designs will go into production.

Responsibilities

• Analyze an existing multi-product architecture to understand its current shape before proposing changes

• Provide evidence-based assessment of code and design quality across product lines (correctness on money/stock paths, security posture, coupling, and capacity risk)

• Write and review RFCs and ADRs, making assumptions, failure modes, capacity, and security explicit

• Design extend-vs-rebuild decisions with incremental, reversible migration paths and rollback stories

• Work within real constraints including multi-currency payments, fraud and abuse exposure, PCI DSS scope, third-party supplier integrations, and large traffic spikes

Requirements

• 8+ years of software engineering experience

• Anticipate future use cases and minimize cost of change (express trade-offs in cost terms)

• Anticipate scaling limits across a domain before they bind, including shared dependencies (authentication, supplier integrations)

• Review others’ designs constructively and identify scalability or change-cost risks early

• Collaborate as a technical peer (including productive disagreement with Staff engineers/managers)

• Use architecture patterns for iterative, autonomous development and future scaling (e.g., bounded contexts; minimize cross-service dependencies)

• Design for expected peak load and validate limits with testing

• Build reusable components for other teams, with documentation and migration paths

• Design with abuse in mind by default (rate limits, velocity checks, idempotency)

• Read and explain every line of AI-generated code you ship

• Testing that covers edge and failure cases

• Strong command of OWASP Top 10 and secure-by-default habits (secrets management, input validation, data handling)

• Strong written English for asynchronous RFC and review collaboration

• Collaborative style: present options with trade-offs and argue with reasoning

Benefits

• 100% remote work

• Long-term collaboration on challenging products

• Continuous development of hard and soft skills with an experienced team
