About Inniovate
Inniovate is a fast-moving product company building real-time, connected technology that sits at the intersection of IoT, mobile, and cloud. We're entering a significant growth phase and we're looking for a backend engineer who thrives in that environment — someone who can architect for scale, ship with pace, and help set the engineering standard as we move from being UK and Ireland focus to being a truly global company.
The Role
We need a seasoned Backend Developer who is deeply comfortable with Node.js and TypeScript, and who has built production systems that handle real-time data, complex integrations, and the kind of reliability that matters when physical devices are in the loop. You'll work closely with a small, talented team — owning backend architecture decisions, building APIs and services that power our mobile and IoT products, and helping to establish the engineering practices that will carry us through our next stage of growth.
What You'll Be Doing
- Designing, building, enhancing and maintaining scalable backend services and APIs
- Leading architectural decisions that support rapid growth and increased user demand
- Working with real-time communication systems (WebSockets / socket.io)
- Managing Redis for pub/sub, caching, and job queuing
- Building and maintaining robust integrations with third-party APIs — including solid error handling, rate limit management, retries, and monitoring
- Owning observability: structured logging, metrics, and alerting
- Collaborating with AWS infrastructure (RDS, Lambda, IoT Core) and understanding how it all fits together at the networking level (VPCs, subnets, NAT gateways, VPNs)
- Mentoring junior developers and contributing to a strong engineering culture
- Integrating with third party softwares to enhance our offerings
What We're Looking For:
Essential
- 5+ years of professional backend development experience
- Strong Node.js + TypeScript skills — this is your primary tool
- Solid experience with WebSockets / socket.io
- Good grasp of REST API design: auth, error handling, versioning
- Comfortable with Redis (pub/sub, caching, queues)
- SQL and relational database experience — AWS RDS / MySQL preferred
- Experience with message/job queues (Bee Queue, SQS, or similar)
- Solid logging and observability practice (structured logs, metrics, alerting)
- Proven experience with AWS services and a real understanding of AWS networking
- Comfortable working at pace in a small, high-trust team
Nice to Have
- Exposure to IoT systems — firmware interaction, physical device constraints, debugging connectivity
- Experience with real-time mobile app communications
- API versioning and backward compatibility experience
- Monitoring and alerting setup experience
- A track record of scaling systems through periods of significant growth
Why Inniovate?
- You'll have genuine ownership — architecture decisions here matter, and you'll make them in conjunction with the rest of the team
- We're a product company, not an agency — you'll build things that last
- The team is small and highly capable — no bureaucracy, no hand-holding
- Derry-based with flexibility for the right person
- You'll be joining at exactly the right time to shape how we grow as we aim to go global with our unique solution
- Equity is up for grabs for successful candidates.
