Pynea is a challenge-based interview intelligence system, powered by AI. We help companies hire faster and smarter by replacing CV-noise with evidence from real work and real human capability.

We’re in full build mode towards launch - and we operate like a top-tier creative engineering studio: small team, high taste, high ownership, no corporate theatre.

We’re hiring a Senior Backend Engineer to build the enterprise backbone: high-concurrency APIs, event-driven systems, and reliability foundations that turn messy hiring inputs into trusted signal : fast, secure, GDPR-safe, and ready to scale from day one. If you love turning evolving intent into production-grade systems that don’t flinch under load, you’ll thrive here.

The role (what you own)

You’ll own the enterprise backbone across a few high-impact areas:

Enterprise-grade architecture

Standardised patterns from intake → build → QA → deploy → measure. Secure by default, GDPR-safe, compliance-ready.

Full-stack workflow automation

Scalable GraphQL APIs, integrations, event-driven systems, monitoring/logging, error handling, and documentation that scales beyond you.

What you’ll build (real scope)

• High-concurrency APIs and reliability mechanisms (retries, idempotency, queues) • Event-driven systems that don’t drop data • Dashboards/reporting surfaces that remain consistent under load • Cloud-ready architecture across GCP (with minimal AWs for asset management) • Systems designed to ship fast, stay robust, and scale cleanly
