Senior Backend Developer (Node.js + AWS)
B2B | Hybrid or Remote Kraków/ Rzeszów

About us

Tectonic Interactive builds live interaction systems for TV shows and streaming platforms. We handle millions of users in real time – votes, audience decisions, traffic spikes and zero room for error on air. These are not typical CRUDs, but high-load systems.

Your role

You will develop and maintain the backend of systems operating under very high load.

Scope

• development of the backend for voting and interaction applications,

• designing APIs for hundreds of thousands of requests at peak,

• scaling and system stability in AWS,

• automation of deployments and monitoring,

• participation in incident handling during live broadcasts.

We work as a team without rigid role division – you have real influence on architecture and technical decisions.

Technical requirements

• very good knowledge of Node.js / TypeScript,

• experience with NestJS, Fastify or Express,

• Docker and CI/CD (GitHub Actions),

• practical experience with AWS (including ECS, SQS, RDS, S3, ElastiCache),

• experience with databases MySQL, Redis,

• good understanding of scaling, performance and High Availability,

• creating unit and integration tests.

An advantage would be

• Terraform / Serverless,

• MongoDB, DynamoDB,

• experience with high-traffic systems.

We’re not looking for a DevOps-by-title, but for a backend engineer who understands infrastructure.

We offer

• work on systems serving millions of live users,

• real influence on the product and architecture,

• small, experienced team,

• paid vacations and a training budget,

• flexible work (hybrid or remote),

• attractive B2B compensation.
