Why rinf.tech?

Why do we do what we do?

We inspire one another to share our tech-works in this amazing and abundant world. So we became developers, innovators, thinkers, software builders, and hardware makers!

Our Vision!

Founded in 2006 with 650+ engineers & global presence (8 delivery centers in Europe & North America) we strive to become a leading East-European technology partner for growing organizations in need of digital transformation of their products and services!

What you’ll do

• Lead the technical design of complex features and write technical design documents and architecture decision records;
• Own end-to-end delivery of large initiatives, breaking them into increments the team can ship;
• Design solid event-driven flows: event contracts, versioning, duplicate-safe processing, retries, failed-message handling and replay;
• Design for multi-tenancy, security and access control (Keycloak/OIDC, role-based access, tenant isolation);
• Improve performance and reliability across Node.js services, PostgreSQL and queue processing;
• Drive observability standards (structured logging, OpenTelemetry tracing, Prometheus metrics, Grafana alerts) and reduce operational noise;
• Set and model engineering standards: code quality, testing strategy (unit, integration, contract), CI/CD practices;
• Work with QA to make the system easy to test and to keep end-to-end automation stable and fast;
• Review designs and code across the team, and mentor mid-level and junior engineers;
• Lead or support incident response and run blameless post-incident reviews;
• Work with architects and other Phenom/ReX teams on cross-team dependencies and shared platform decisions;
• Help with hiring, interviews and onboarding.

What you need to be successful

• 6+ years of professional software engineering, with a strong focus on JavaScript/TypeScript;
• Deep expertise in Node.js back-end development and strong working knowledge of React;
• Proven experience designing and running distributed, event-driven systems (queues, pub/sub, background jobs) in production;
• Strong experience with API design (GraphQL and/or REST) and relational data modelling (PostgreSQL);
• Track record of leading technical design and delivering complex features across teams;
• Hands-on experience with observability and production operations: metrics, logs, tracing, alerting, incident handling;
• Solid understanding of security basics: authentication and authorization, role-based access, secure handling of sensitive data;
• Experience with cloud-native deployment (AWS, Docker, Kubernetes);
• Experience mentoring engineers and shaping team engineering practices;
• Clear written and spoken communication with both technical and non-technical stakeholders.

Nice to have

• Experience building multi-tenant or whitelabel SaaS products;
• Experience splitting services out of a monolith or modular monolith;
• Experience with document or file-processing pipelines and third-party integrity or compliance integrations;
• OpenTelemetry, Grafana (Loki/Tempo) and Prometheus at scale;
• Contract testing (e.g. consumer-driven contracts for APIs and events);
• Background in academic publishing, research integrity or regulated domains.
