This position is open exclusively to Ukrainian residents within Ukraine (preferably Kyiv).
We’re looking for a Senior Node.js Engineer to build and evolve our web platform, with a primary focus on Node.js, React, and PostgreSQL development. Main responsibilities: * Contribute the majority of your time to product development: design, implementation, and testing. * Deliver high-quality Node.js services and React UI changes; write maintainable, well-tested code. * Design SQL beyond ORM abstractions; analyze queries, optimize performance, and evolve schemas. * Improve reliability by creating runbooks, post-incident reviews, and automation for recurring tasks. * Own rapid first response during business hours via instant messenger and an emergency phone line. * Triage, reproduce, and diagnose issues across the stack; restore service quickly where possible. * Apply safe workarounds, configuration tweaks, or hotfixes; execute rollbacks when needed. * Escalate efficiently to the development team with clear context, logs, impact, and proposed next steps. * Communicate status and timelines to internal stakeholders and customer contacts. * Enhance monitoring and alerting; instrument services for actionable logs, metrics, and traces.
Requirements: * Senior-level experience building production Node.js applications. * React familiarity for practical UI issues diagnosis. * PostgreSQL expertise and strong SQL skills beyond ORM usage, including query design and tuning. * Hands-on experience with incident triage, root-cause analysis, and production debugging. * Comfortable with Linux servers and on-prem fundamentals (DNS, TLS, certificates, basic networking). * Proficient with Git workflows and CI/CD practices. * Familiarity with observability (logs, metrics, traces) and structured troubleshooting.
Nice to have: * Python or Go experience for tooling, services, or automation. * Solid understanding of Docker for local development and packaging. * Knowledge of reverse proxies/load balancers (Nginx, HAProxy, Traefik). * Exposure to container orchestration (Docker Swarm or Kubernetes) and IaC (Terraform/Ansible). * Practical experience in diagnosing infrastructure problems: resources congestions, network connectivity issues, PKI and other protocol-level security problems. * Experience with Sentry, Prometheus/Grafana, ELK/OpenSearch, or OpenTelemetry.
Hiring Process: * Resume review — up to 5 business days. * Introductory meeting with the Systems/Software Architect. * Technical interview with several team members. * Background check. * Offer discussion.
We Offer: * Competitive compensation. * Hybrid work model: combination of in-office and remote work as needed. * Paid vacation — 21 business days per year. * Paid sick leave. * Exposure to intersecting domains: software development, information security, and cloud/on-prem infrastructure engineering. * Experience in mission-critical projects.
