Senior Frontend Engineer — Build the Future of Cybersecurity

Job details

Posted Monday 09 February 2026
Job type Permanent
Reference 468
Recruiter Name Ronan O'Sullivan

Why This Role Matters

Most cybersecurity tools are clunky, overwhelming, and built for machines—not humans. You'll change that.

Our client, based in Galwa,y is rethinking how organisations defend themselves at scale. They're building elegant, powerful products that security teams actually want to use—tools that turn massive data sets into clear insights and help defenders move faster than attackers.

This isn't about ticking boxes or maintaining legacy code. It's about solving genuinely hard problems, shipping work that matters, and seeing real users rely on what you build every single day.


What You'll Actually Do

Ship modern, production-grade SPAs using React, TypeScript, and cutting-edge web tech—fast, intuitive interfaces that handle complex data with ease.

Work directly with users. You'll collaborate with customers, iterate based on real feedback, and see your work make an immediate impact.

Own your craft end-to-end. Design decisions, architecture, deployment, iteration—this is your product, and you'll have the autonomy to shape it.

Solve problems, not tickets. You won't be handed detailed specs or asked to code to someone else's design. You'll be given real problems and trusted to create the right solution.

Move fast without breaking things. CI/CD pipelines, strong DevOps culture, and a team that values both speed and quality.


What Makes You a Great Fit

8+ years building production software—web, UI, backend, or full-stack experience
Deep JavaScript/TypeScript expertise and a solid grasp of modern frontend architecture
React experience preferred (or strong skills in Vue, Angular, Svelte—we care about aptitude)
Comfortable wrangling complex data into performant, user-friendly interfaces
Startup/scale-up DNA—you thrive in fast-paced, high-ownership environments where your voice matters

Bonus points: experience with GraphQL, WebSockets, PWAs, or monorepo workflows


The Tech You'll Use

Frontend: React, TypeScript, Material UI, Storybook
Real-time & Performance: Web Workers, WebSockets, PWA architecture
Integration: REST, GraphQL, CQRS patterns
Workflow: Monorepos, CI/CD, DevOps/SecDevOps, strong UX collaboration
