Full Stack Developer

Hello, we're Honest. 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.

Role overview: 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. In this role, you'll help shape the technical direction of our product, looking beyond the standard stack to introduce new technologies, techniques, and ideas. You'll play a key role in the full development lifecycle, delivering high-quality features and continuously improving how our backend and frontend platforms are built. You'll work across our API, databases, network and infrastructure, internal tools (including team and customer-facing dashboards) and web-based interfaces, creating experiences that truly delight our users. Reporting to the Head of Engineering, you'll be a core part of our small but mighty tech team, collaborating closely with developers and product to make a meaningful impact across the full stack.

Job requirements: You're a strong generalist with experience across both frontend and backend. You're fluent in modern TypeScript but you're language-agnostic and enjoy picking up new languages and frameworks. You're comfortable with CI/CD workflows and typical DevOps processes relating to deployment of Dockerised Node applications to Cloud Hosting environments (esp. GCP). You have more than a passing familiarity with relational databases (e.g. Postgres) and writing efficient SQL. You're pragmatic, curious, and motivated by solving real user problems. You're comfortable owning projects end-to-end in fast-moving environments. You're committed to clean, maintainable and well-documented code. You're a clear communicator, who collaborates effectively. You're comfortable asking questions and challenging assumptions. You're excited by AI and its potential to accelerate development and support rapid iteration and experimentation.

Benefits: Salary: 70,000 - 80,000. Ownership in Honest through our EMI option scheme. 25 days of annual leave, plus all bank holidays. Your birthday off each year on us! A hybrid-first working environment with at least 1 day per week in the London office. An Honest sim, and refurb phone on us. 1 paid volunteering day each year. Wellbeing budget through Heka. Cycle to Work scheme. 500 annual learning budget. Regular in-person team socials. Private medical insurance.
