Back-end Developer

Elockers runs the smart-locker platform that festivals, venues, and events across six countries rely on for real-time payments and marketplace-style payouts, including on-sale moments where a large share of a site's lockers can sell out within a minute. We're live in eleven countries, with further international expansion and two acquisitions underway.

Our platform is genuinely strong: microservices architecture (~30 services), event-driven data flow, and a payments stack built for a real marketplace. This isn't a role about fixing something broken. It's about strengthening a platform that already works well, hands-on.

We're looking for an exceptionally strong, hands-on Senior Back-end Developer to work deep in our microservices platform, where software, payments, and physical hardware come together. You'll match our current technical level and raise it through your own hands-on work. You’ll design, build, and debug complex systems yourself, with real technical depth.

• Our microservices platform, with Node.js and modern architecture patterns at the core
• Cloud-native engineering on DigitalOcean App Platform: deployment, scaling, monitoring, and production reliability
• Reliability at peak: real-time payments and traffic spikes during live events, with zero tolerance for downtime
• Our Adyen-based payments and marketplace systems, and how our software connects to physical locks and hardware
• Engineering discipline: CI/CD, documentation, and AI-assisted development, as we raise an already-strong platform further

Our stack today

Microservices (~30 services), moving toward Node.js at the core. Adyen for payments. Kafka, ClickHouse, Metabase for data. React Native/Expo for mobile. DigitalOcean, Sentry, New Relic, Jira for infra and tooling.
