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 Lead
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.
This is an
70% IC / 30% management
role. The majority of your time is spent writing production code, making architecture decisions, and raising the technical bar. The remaining 30% is people work: 1:1s, growth conversations, unblocking the team, and bridging backend with the rest of the company.
If you want to step away from the keyboard, this isn't the role. If you want to lead by doing, read on!
WHAT YOU'LL DO
As an IC (70%)
Design, build, and maintain robust backend services and APIs using
NestJS
and
TypeScript .
Own architecture and delivery on our core systems: gamification engine, in-app economy, map infrastructure.
Architect and optimize
PostgreSQL
schemas and queries for performance at scale.
Implement and manage
Redis
caching strategies.
Leverage
Google Cloud Platform
(Cloud Run, Pub/Sub, Cloud Storage) for deployment and infrastructure.
Drive technical decisions end‑to‑end, from design to production.
Reduce bus factor on critical systems: document, distribute ownership, harden.
Champion AI tooling adoption to amplify team throughput.
Anticipate technical risk before it becomes an incident.
As a Lead (30%)
Improve backend processes and delivery, track team performances.
Work closely with QA and Mobile team to improve day‑to‑day operations.
Manage 5 backend engineers: 1:1s, growth conversations, direct performance feedback.
Translate product and business priorities into scoped, executable technical work.
Be the communication layer between backend and the rest of the company, proactively, not reactively.
Improve release discipline and post‑release stability across the team.
Identify and close skill gaps through mentoring and thoughtful delegation.
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.
