Senior Full stack engineer

Pynea is an AI hiring intelligence system built around evidence, not impressions: real capability in context, not past credentials, with a candidate experience designed to show more than a CV.

Most hiring systems turn people into data: scanned, skimmed, forgotten. We’re building the opposite. A voice-first, challenge-led application journey that feels like a conversation from the start, and gives hirers signal they can trust.

We’re in full build mode towards launch, and we operate like a top-tier creative engineering studio: small team, high taste, high ownership, low bureaucracy.

We’re hiring a Senior Fullstack engineer to build the enterprise backbone that makes all of this possible: 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.

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

What success looks like

• Features ship fast without hacks
• The system scales from 10 → 10,000+ users with confidence
• Reliability is visible: monitoring, alerts, error tracking, runbooks
• Security is default: permissions, audit trails, GDPR-safe practices
• Clear scoreboard: uptime, latency, error rates, queue health, enterprise readiness metrics
• AI is applied with taste and rigour: you help us ship AI-powered capabilities that are measurable, monitored, and safe, not magical or brittle
• You’re a visionary when it comes to AI and its impact on modern engineering: you bring new ideas and practical patterns that raise delivery speed and quality without compromising correctness

Who thrives here

You dive in and help debug issues collaboratively. You ship production-grade systems quickly. You make sharp trade-offs without sacrificing reliability. You communicate crisply async (short Looms, diagrams, notes). You enjoy building enterprise systems that teams can depend on.

You’re AI-native in practice. You’re curious enough to explore what’s possible and disciplined enough to ship what’s reliable. You can build AI into the product in a production-safe way (guardrails, evals, monitoring, failure modes), and you bring a strong point of view on how AI should reshape the engineering workflow, raising speed and quality without sacrificing correctness.

Must-haves

• NodeJS, GraphQL (NestJS), PostgresSQL
• Data structures
• OOP principles
• Understanding of complexity principles and correct approaches
• Experience with AI and LLMs (including but not limited to Gemini)
• Strong analytical and problem-solving skills in a fast-changing environment
• Reliability mindset: monitoring, logging, retries, QA, incident-aware design
• Comfortable operating in a sprint with incomplete context and tight deadlines
• Experience in GCP, Prisma and terraform

Additional Skills

• Code quality & maintainabilityWrites readable, consistent, and well-structured code
• Understands trade-offs between speed of delivery and long-term maintainability
• Comfortable working in a shared codebase with established guidelines
• Testing mindsetUnderstands the value of unit, e2e, and regression tests to minimise disruption to the frontend apps
• Writes testable code and doesn’t rely solely on manual testing
• Collaboration & ownershipCan work closely with frontend, product, and design teams
• Takes ownership of features end-to-end
• Comfortable giving and receiving code reviews
