As a Senior Backend Node.js Developer, you know what it takes to build truly production-ready APIs. You’re an expert in writing clean, readable, maintainable, extensible, and testable code. You’re excited about all things serverless, designing distributed microservices and event-driven architectures.

This is an excellent opportunity to join a growth-stage technology start-up and experience building scalable and performant backend distributed systems using a modern tech stack.

We’re proud of our code quality. Our codebase has 90%+ unit tests coverage. We encourage publishing open-source software and cleaning up the tech debt. We write TypeScript and Node.js 16/18, conduct peer code reviews, backend excellence meetings, maintain shared coding standards, practices, linters, presets, etc.

We’re looking for intellectually curious, motivated developers who want to work on a B2B product to deliver value to tens of thousands of users from companies such as Glovo, Avon, Nespresso, HelloFresh, and Herbalife.

We’re looking for someone who has:

4+ years of commercial experience building backend with TypeScript (or JavaScript) & Node.js
Strong desire to ship software fast and efficiently, prioritizing practical solutions and delivering business value over lengthy theoretical discussions.
At least an Upper-Intermediate level of English
Experience with multiple AWS services (beyond just EC2 & S3) such as Lambda, SQS/SNS/Kinesis/EventBridge, Step Functions, DynamoDB, RDS (PostgreSQL), API GW
Hands-on experience with large SQL and NoSQL databases and their constraints
Proficient in microservice architectures, adept at decomposing large systems into smaller, scalable, and maintainable components.
The habit of writing unit tests using jest.js
Excellent communication skills, both written and verbal, as the role may involve contributing to the internal technical wiki and mentoring junior developers

You will:

Build backend APIs in a self-sufficient delivery team that ships code to production frequently
Write technical designs for the features you develop and execute on them
Take ownership of the features you built and shipped to production, ensuring their stability, performance, and reliability. This includes monitoring your code for potential issues and proactively addressing bugs
Utilize AWS services to build Infrastructure as Code using Terraform, taking full responsibility for creating and maintaining the necessary AWS infrastructure to support the features you develop and ensuring their optimal performance
Regularly conduct code reviews and act as a competence lead for junior developers on your team, providing guidance, support, and mentorship to help them succeed in their careers and continuously grow their skills and expertise
