Senior Backend Engineer / Node-Typescript-AWS

What would you do?

- Own the design, development, and maintenance of the backend microservices behind Torre de Control, Instaleap’s operational visibility platform for all of its clients, with close support from a Tech Lead and an Engineering Manager.

- Lead the technical and product definition of new features: analyze the problem, challenge the scope, propose the solution, and take responsibility for the outcome.

- Work closely with product, frontend, and QA to build features end-to-end with full business context.

- Provide guidance and mentorship to mid-level and junior engineers, and take part in code reviews and architecture decisions.

- Handle technical support and incident resolution for your services, including participation in the team’s on-call rotation.

- Close security vulnerabilities and improve the performance, scalability, and architecture of our services.

? Your experience has been shaped by

- 5+ years of backend experience with Node.js and TypeScript as your main stack.

- Recent experience at startups or product scale-ups, in environments where the day can change and you balance roadmap, support, and incidents.

- Product experience: you’ve helped define what gets built and why, not just how it gets implemented.

- Real ownership of production microservices: you didn’t just write code, you understood the system and responded when something went wrong, including on-call rotations.

- Production experience with AWS (for example SQS, Lambda, ECS, or DynamoDB).

- Integration of messaging systems such as RabbitMQ or SQS.

- Experience mentoring or guiding mid-level and junior engineers.

- Command of relational and non-relational databases (PostgreSQL, DynamoDB, Redis, or similar), with the judgment to choose the right one for each case.





- Strong engineering principles: design patterns, unit and integration testing, SOLID, and clean code.

- English proficiency at B2-C1 level minimum.

? Your SuperPowers

- You get truly involved: you understand the business context, question the problem before coding the solution, and own the result.

- You have your own technical judgment, and you know when to lean on the TL and the manager to make better decisions.

- You’re comfortable in environments where the day can change, without losing focus.

- You use AI as a natural part of your workflow. It’s not an experiment, it’s the standard.

- Nice to have: hands-on experience with Terraform.
