Why this role matters

At JOIN, we believe hiring should be easy, fast, and fair - for companies and candidates alike. That’s why we’re building intuitive, powerful recruiting software that helps businesses of all sizes find the right people effortlessly.

As our Backend Engineer in Barcelona, you’ll join us at an exciting moment: the launch of our new office in Spain! You’ll play a key role in shaping the future of our product and platform, working with a modern tech stack to deliver robust, scalable features. This isn’t just another job – you’ll be part of building a new engineering hub from the ground up.

What you’ll be doing

Your work will directly impact how thousands of companies and candidates experience hiring. Here’s what that looks like:

• Collaborate with frontend engineers, product managers, and DevOps/platform teams to build meaningful features through our Agile SDLC/Kanban workflow.
• Conduct peer code reviews and contribute to retrospectives to drive continuous improvement.
• Define technical requirements and identify the best solutions to meet team goals.
• Participate in engineering retrospectives focused on testing, architecture, automation, and coding standards.
• Always think beyond the code - you’ll focus on delivering value and improving the user experience for our customers.

Who you’ll work with

You’ll join our Backend Guild, collaborating closely with Product, Platform, DevOps, and Frontend teams. We care deeply about quality, performance, and a great developer experience – supported by clean architecture, code generation, linters, templates, and test-driven development.

What we’re looking for

We don’t believe in checklists - but if most of these apply to you, we’d love to chat:

✔ 5+ years of backend development experience.

✔ 2+ years of experience with a strongly typed language or TypeScript.

✔ Strong experience with RDBMS (raw queries or via ORM).

✔ Solid background in unit and integration testing.

✔ Experience with message brokers (SNS, RabbitMQ, Kafka, Google Pub/Sub, etc.).

✔ Bonus: Experience with Node.js, GraphQL, GCP or AWS, gRPC and protobufs.

✔ Bonus: Strong grasp of SOLID principles.

Our Values
