Senior Frontend Engineer (React + AWS)
Location: Belfast (Remote)
Ref: OCHO-SFE0425
OCHO - Building Teams
We're partnered with an established yet fast-moving technology company based in Belfast that's building real impact at scale - powering workflows for some of the world's largest enterprises. Their engineering culture is modern, modular, and product-led - and they're looking for a Senior Frontend Engineer who thrives in TypeScript ecosystems, understands cloud-native architecture, and has a keen eye for well-engineered, scalable interfaces.
This team is deeply collaborative, with a flat structure and strong emphasis on knowledge-sharing, performance, and autonomy. You'll be contributing across design, development, testing, observability, and CI/CD - not just shipping UI, but owning how the platform functions end-to-end.
What You'll Be Doing
Leading the design and implementation of frontend applications using React (Hooks, Context, TypeScript) in a modern monorepo architecture.
Building scalable frontend systems powered by AWS, integrating with serverless APIs and event-driven backends.
Owning frontend code quality, performance, and accessibility, with a strong focus on developer experience and reusability (think Storybook-style component libraries).
Mentoring and pairing with engineers, helping shape best practices in testing (Jest, Cypress), release automation, and frontend observability.
Contributing to platform-wide decisions, from auth and analytics to real-time event streaming and PWA optimisation.
Collaborating with backend and DevOps engineers in a CI/CD-led environment using modern infrastructure tooling (GitHub Actions, Terraform, ArgoCD, etc.).
What We're Looking For
6+ years' commercial experience, including React + TypeScript at scale.
Strong architectural instincts - you've built or refactored monorepos, component libraries, or large-scale applications.
Hands-on experience with AWS, ideally including Lambda, API Gateway, CloudFront, and S3.
DevOps-aware mindset - you're comfortable discussing pipelines, deployments, and performance budgets.
Proven success in collaborative teams and a passion for mentoring and technical leadership.
Bonus if you've worked with NestJS, Next.js, GraphQL, WebSockets, or mobile/PWA delivery pipelines.
What's on Offer
Competitive salary + performance bonus
25 days holiday + public holidays
Remote-first with flexible hours
Health and wellness programme
Regular tech talks, team meetups, and L&D budget
Clear progression framework
10% (individual ) and 10% ( company ) pension allowance
