Full job description

HALOS is an advanced body camera and cloud software scaleup, working with some of the biggest names in security, services, and law enforcement. At HALO, we're passionate about safety and innovation, constantly staying ahead of threats and reducing risk.

What sets HALOS apart is not just the cutting-edge technology we develop but the culture we've nurtured. Our team embodies openness, transparency, and a "one team" spirit. We're a group of passionate individuals, all working on exciting and impactful projects. Here, you'll find an environment that fosters collaboration, creativity, and a shared sense of purpose.

What you’ll work on

We’re building the next generation of AI-driven video forensic and evidence analysis tooling for our body-worn camera platform. As a Senior Frontend Engineer, you’ll help shape the user experience behind complex investigative workflows including video review, transcription, timeline analysis, streaming, and AI-assisted insights.

This is a hands-on engineering role focused on building fast, reliable, and intuitive interfaces for large-scale media and data-heavy applications. You’ll work closely with backend engineers, product, and design to deliver modern React applications that balance performance, usability, and maintainability across mission-critical workflows.

Day to Day

Build React applications using TypeScript, Tanstack Router/Query, and Shadcn UI
Design type-safe APIs with tRPC spanning frontend and backend
Develop AWS Lambda functions and manage infrastructure with AWS CDK
Work across React (Vite) and Next.js monorepos using Turbo and pnpm
Write tests with Vitest and Playwright
Optimize performance (bundle sizes, Core Web Vitals, query caching)
Review code, maintain strict TypeScript standards, and ensure security best practices with Zod validation

Your Qualifications

You're a pragmatic engineer who values simplicity and type safety. You've shipped production apps at scale and understand trade-offs between abstraction and clarity. You're experienced in taking features from requirements through implementation to production.

Required:

5+ years professional TypeScript/JavaScript development
Expert React with modern patterns in SPA applications
Modern build tools (Vite, Turbo, webpack) and monorepo management

Helpful:

tRPC, Tanstack ecosystem (Query, Router, Table), & Next.js
AWS CDK
Tailwind CSS, Shadcn/Radix components
Zod validation, Playwright E2E testing
Performance optimization and Web Vitals experience
React Native

Benefits

Generous Annual Leave Allowance

Competitive salary and commission/bonus package

Employer matched pension scheme

Learning and Development opportunities

Private Health Insurance

Cycle to work scheme & Home & Tech scheme through salary sacrifice

Regular company events and social initiatives

Diversity & Inclusion

We’re an Equal Opportunity Employer and embrace a diversity of backgrounds, cultures, and perspectives. We do not discriminate on the basis of race, colour, gender, sexual orientation, gender identity or expression, religion, disability, national origin, protected veteran status, age, or any other status protected by applicable national, federal, state, or local law.

Don’t meet every single requirement? At HALOs we are dedicated to building and promoting a fair and inclusive workplace where everyone can flourish, reach their full potential and truly belong. We recognize that diverse teams foster a more creative and productive environment. So, if you’re excited about this role but your experience doesn’t perfectly align with the job description, we encourage you to apply anyway. You might just be who we’re looking for - for this role, or perhaps another.
