Descrizione del lavoro

❄️ We’re currently on a winter break, and enjoying one too many mince pies. If you're applying now, we'll be in touch in January. We can't wait to read your application.

The clue’s in the name: we’re the network doing mobile right.

We’re on a mission to fix a broken industry and show there’s a better way to do mobile, for both people and the planet. For too long, the big mobile networks have been taking advantage. We think customers deserve better. Way better.

So instead of counting profits and doling out the bare minimum, we give customers what they actually want. That means bills that drop every month, support in seconds, and sustainability efforts that shrink their carbon footprint.

Powered by cutting‑edge technology, we’re building the next generation mobile network. This includes our unique Smart SIM that offers unbeatable coverage and free use of essential 500+ apps worldwide.

That’s not all. We’re also the UK’s first B Corp mobile network, a carbon‑negative company and member of 1% for the Planet.

But building the world’s best mobile network requires having the right people to help us do it. That’s where you could come in.

Like the sound of Honest? Read on. This could be the start of something exciting.

We’re looking for a talented and curious Full Stack Developer to help take our product to the next level.

Our engineering and product teams are already disrupting the industry with our unique, 4 network, data‑only product, Smart SIM. But we know there’s much more to build. That’s where you come in.

Responsibilities

• Build and develop our React Native app, delivering new features, fixing issues, and reducing technical debt.
• Develop web applications using React/TypeScript, including customer‑facing account management and internal dashboards.
• Help to maintain backend APIs, adding attributes and endpoints to support new features and improvements.
• Design and implement asynchronous workflows to manage customer and service lifecycle requests (experience with Temporal is a plus).
• Collaborate in code reviews and architecture discussions to maintain high engineering standards.
• Troubleshoot and resolve production issues across the full stack.
• Work cross‑functionally with product, customer ops, and marketing team to deliver seamless user experiences.
• Help shape engineering best practices and build internal tools to support our team.
• Own projects end‑to‑end in fast‑moving environments.

Qualifications & Experience

• Strong generalist with experience across both frontend and backend.
• Fluent in modern TypeScript but language‑agnostic and enjoy picking up new languages and frameworks.
• Comfortable with CI/CD workflows and typical DevOps processes relating to deployment of Dockerised Node applications to Cloud Hosting environments (esp. GCP).
• More than a passing familiarity with relational databases (e.g. Postgres) and writing efficient SQL.
• Pragmatic, curious, and motivated by solving real user problems.
• Committed to clean, maintainable and well‑documented code.
• Clear communicator who collaborates effectively.
• Comfortable asking questions and challenging assumptions.
• Excited by AI and its potential to accelerate development and support rapid iteration and experimentation.

Bonus Points

• You have experience working in a fast‑paced start‑up environment.
• You have experience GCP.
• You have experience in Temporal.
• Introductory call with our Head of People & Impact (30 mins).
• Interview with our Head of Engineering and Backend Engineer (1 hour).
• In‑person interview: 1‑2 hour interactive live coding session, 30 min break, 1 hour interview with Andy and Josh, our Co‑Founders.

What’s it really like to work in the engineering team at Honest?
