Help us build the future of real-time retail execution
We're the Execution Intelligence platform for CPG brands, and we're looking for a Full Stack Engineer who takes ownership of their work, from picking up a ticket to seeing the change running in production. You'll build on the systems we already have, backend through to front end, and own your work through to deployment.
This is a mid-level role with real breadth. Your depth is in the backend, and you want to grow across front end and deployment rather than specialise. AI fluency is what makes that breadth workable. Our Head of Engineering owns the architecture and system design, so you have a system to learn from and someone to learn it with.
Why this role matters
Customers experience our product as a whole. They don't see the boundaries between backend systems, APIs and interfaces. They see whether something works, whether it solves their problem and whether they can rely on it. That reliability is what wins new customers and what keeps the ones we have.
With our strong backend depth existing in the team, what we need alongside it is someone who works across the stack, connecting the underlying technology to what customers actually interact with, and takes it through to production.
Your mission: get working software into customers' hands and keep it reliable, so what we promise and what we deliver are the same thing.
What You'll Do
Full stack implementation
- You build and maintain features across the stack, backend through to front end
- You implement against the existing architecture and system design, test your work and see it running
- You own the whole feature, from the data layer through to what the user interacts with
Integrations and backend connections
- You build and maintain the connections between our platform, our internal services and customer systems
- When data is not flowing or an integration is failing, you investigate it, trace it across services, fix it and deploy the fix
- You work directly with our delivery and machine learning teams to turn what they need into a working connection
Deployment and release pipeline (CI/CD)
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- You own the CI/CD pipeline your work runs through, keeping the route from commit to production reliable, and you deploy your own changes
AI automation
- You own how AI is used to improve your delivery, building automation into your own workflow and extending it to the engineering work around you
You'll also be expected to undertake additional tasks as requested by the Head of Engineering.
Requirements
Background and experience
Essential
- Around four years' equivalent experience building and shipping software as part of an engineering team
- Experience in a start-up or small engineering team of fewer than ten people, where you have worked close to the whole product rather than one narrow area
- You have owned at least one project front to back across the full stack, from first commit to running in production. Two or more is a strong signal
- Recent experience using AI tools to drive a project end to end
Desirable
- You have designed a web system yourself, rather than only worked within one someone else designed
Technical skills
Essential
- Python backend development, including async paradigm
- REST API design - FastAPI, or a comparable Python framework
- PostgreSQL and relational database design - SQLAlchemy, or equivalent ORM experience
- Understanding of web system design principles and how components fit together
- React and TypeScript, enough to connect front end to backend and carry a feature through. Front-end specialist depth is not expected
- AI fluency. We have no preference on which tools, and we will ask you which you use and how
Desirable
- Distributed systems, and message queueing such as RabbitMQ
- GraphQL for the frontend to backend connection (Strawberry used on the backend side, Apollo on the frontend)
Trained on the job
- Terraform, infrastructure as code and the GCP stack. Some baseline understanding of deployment helps, and we will train the depth in your first three months
How You Work
- You take initiative on cross-team threads. You follow the wider technical discussions and get involved rather than waiting to be assigned
- You handle ambiguity by unblocking first. Faced with a live issue, you get a hotfix in to stop the immediate problem, then bring the team together to plan the proper fix and drive it through
- You ask for help rather than handing work back. When you get stuck you come in for advice, work it through, then carry it forward yourself
- You communicate directly. You say what you have found, what you need and where you are
- You want to spend time with the team in person - with quarterly travel to our London Office and travel at least once a week to Edinburgh
