Role
Who you are
- You're a strong generalist with experience across both frontend and backend development
- You’re comfortable working with modern TypeScript codebases but you’re fundamentally agnostic and enjoy picking up new languages and technologies to suit the task in hand
- You enjoy getting stuck into infrastructure, networking, and DevOps — not just writing app code
- You have experience deploying and managing services in cloud environments (bonus if it’s GCP)
- You’re familiar with relational databases like Postgres and know how to write clean, efficient SQL
- You’re pragmatic, curious, and excited by solving real problems for users
- You’re comfortable owning projects end-to-end and thrive in fast-moving environments
- You value clean, maintainable code and understand the importance of documenting as you go
- You communicate clearly, work collaboratively, and are happy asking questions or challenging assumptions
- You’re keeping pace with the latest developments in AI and are excited and energised by the potential that it unlocks as a tool to support engineers to move fast and experiment
What the job involves
- We’re looking for a talented Full-Stack Developer to join our fast-growing engineering team
- Reporting to and working closely with our Head of Engineering, your day-to-day will involve building and improving both the backend and frontend of our platform. You’ll work across our API, database, network and infrastructure, internal tools (like our team and customer-facing Dashboard), as well as the web-based interfaces our users rely on
- You’ll be an active member of our tech team, collaborating closely with our native iOS and Android engineers, and playing a key role in our product development lifecycle to deliver new features end-to-end
- With endless opportunities for growth in this role, you’ll build hands-on experience in a fast-paced, innovative environment. You’ll use the best tech to help us build, and take our product to the next level
- While this is a full-stack role, your time may lean more heavily toward either frontend or backend depending on the needs of the product and your own strengths. Flexibility and curiosity are key
- Design, build, and maintain scalable backend services and APIs using TypeScript and Python
- Develop intuitive, performant frontend features for internal and customer-facing web tools
- Work with Postgres to design efficient schemas and write performant queries
- Contribute to infrastructure and DevOps – from CI/CD pipelines to monitoring and alerting
- Collaborate on the setup and maintenance of networking and firewall rules using tools like IPTables, Suricata, RADIUS
- Deploy and manage services on Google Cloud Platform, leveraging its managed tools and infrastructure
- Participate in code reviews, architecture discussions, and shaping technical direction
- Support the team in debugging production issues across the full stack
- Work cross-functionally with product, customer, and mobile teams to deliver seamless user experiences
- Help shape engineering best practices and internal tools to support a growing team
- We’ve built a modern and feature-rich API on Nest.JS, a powerful database architecture, and a host of smart and innovative technology platforms to help us achieve super-scale
- We use Typescript for the majority of our backend work, and follow industry best practices to guide our software development lifecycle. On occasion we break out Python for quick scripting tasks, and utilise other tools in our toolbox to get the job done
- As a team, we challenge ourselves to do great work. We collaborate closely to review each other’s code and deliver constructive feedback, to ensure that we use our collective experience, and knowledge to achieve the best results

Our take
Honest Mobile was launched in response to seeing a gap in the modern market for mobiles. Mobile networks were lagging behind, set in their old ways with complicated contracts, overcharging, and keeping customers on hold -being the norm.
To challenge this, the company built Honest Mobile from the ground up to create a better mobile network for customers and the planet. With £150k in funding, Honest Mobile has created the first carbon-neutral mobile network where customers can float between networks. And on top of this, its a registered B-Corporation and plants trees on behalf of its customers.
The mobile industry has many established players who have already spent time dealing with the challenges that Honest Mobile currently faces, like price competitiveness, WiFi functionality, and rural coverage. However, by aiming to capitalise on the consumer trend of eco-consciousness, which many of the existing companies in this space neglect, Honest Mobile aims to grow its customer base. Its performance on Seedrs, an equity crowdfunding platform for startups where it raised more than £3M in an oversubscribed campaign, shows that it is clearly gaining traction in the market.
With sustainability at the core of its mission, the company has released the UK's first recycled SIMs – made from 100% post-consumer recycled plastic. Honest Mobile's next step? Getting get rid of SIMs altogether!
