WHO WE ARE

At Macadam, we've built an app that rewards people for walking. With over 15 million users worldwide, we help individuals turn their daily steps into positive habits for health, wellbeing, and sustainability.

Our team is growing fast, and our ambitions are global. We operate at the intersection of health, gamification, and technology, and we're building a world-class engineering team to support this growth.

If you're passionate about building high-performance backend systems and leading the people who build them, we'd love to meet you!

Please send the CV in English.

THE ROLE

As Backend Engineering Manager at Macadam, you'll own two things at once: the technical quality of our backend, and the day-to-day leadership of a team of 5 engineers. You'll report directly to the Director of Engineering.

WHAT YOU'LL DO

• Build a robust, scalable architecture and a team that operates autonomously.
  

What you’ll be owning:

• Engineering Excellence: Beyond just shipping, you’ll actively improve our backend processes, track performance, and sharpen our delivery lifecycle.

• Collaborative Impact: You’ll work closely with our QA and Mobile teams to smooth out the friction in our day-to-day operations.

• The AI Edge: We don't just use AI tools; we lean on them. I’m looking for someone who trusts AI to multiply their output and who will push our team to grow and iterate faster because of it.

• The Reality: You’ll be leading a team of 5 backend engineers in a NestJS/TS/Postgres/GCP environment. I value clarity, direct feedback, and people who scope problems before they start coding.

WHAT YOU'LL BRING

• 6+ years of experience in backend development, with production systems at scale.

• Deep expertise in TypeScript and NestJS, you're the person others come to with hard questions.

• Strong PostgreSQL skills: indexing, query optimization, schema design at scale.

• Hands-on experience with Redis and Google Cloud Platform.

• Experience with Prisma ORM or equivalent is a strong plus.

• You've led or mentored engineers before, you know how to give direct feedback and grow people.

• You scope before you build and push back when complexity isn't justified.

• Proactive communicator: you surface risks early without being asked.

• Fluent in English.

OUR TECHNICAL TOOLBOX

• Backend: Node.js with TypeScript, NestJS framework, Prisma ORM.

• Database: PostgreSQL, Redis (caching).

• Infrastructure: Google Cloud Platform (Cloud Run, Pub/Sub, Cloud Storage).

• Mobile: React Native with TypeScript.

• Analytics: BigQuery, Mixpanel, Metabase.

• Practices: REST APIs, CI/CD pipelines, code reviews, agile sprints.

WHAT'S IN IT FOR YOU

• Be part of a mission-driven company making a tangible difference in people's lives, one step at a time.

• Real ownership: lead a backend team and ship systems used by millions from day one.

• Opportunities for professional growth, learning, and international exposure.

• A supportive, talented, and passionate international team.

• Offices in the heart of Barcelona.

• Meal voucher.

• Wellness allowance (powered by Urban Sports).

• Private healthcare (Alan).

• Hybrid working culture with international flexibility.

• 4 Macadam holiday days.

• Friday Team lunch.

• Company events and offsites.
