The Role
We’re now looking for a strong generalist Senior Full-Stack Engineer to bridge PlannerPals application development with a strong background in building out solutions and delivering it as production ready PRs. AI tooling is not the job. LangChain, Pydantic, RAG, “built agents” can be learnt as part of the job. The job is focused on engineering judgement, taste, data, and not silently introducing a security vulnerability.
You will focus on:
- Designing and building key features of our solutions
- Development and design of CI/CD pipelines, including Infrastructure as a Code and the enablement of developers
- Building and deploying AI agents to production.
- Ensure that coding and testing standards are upheld
This is a fully UK Remote role and offers the opportunity to work closely with the founders at a defining stage in our growth.
Responsibilities
Solution design
- Own the end-to-end solution design for new features within a defined architecture framework
- Make pragmatic decisions about trade-offs (scope, performance, scalability, security) in a fast-moving environment.
Hands-on development
- Take ownership of complex or high-impact pieces of work, especially where the architecture, integrations or performance considerations are non-trivial.
- Design, build and optimise the journeys of our service using our tech stack:
- Backend: Python
- Frontend: React + Flutter
- Data / Infra: Postgres, AWS ( S3, ECS etc.)
- Write high-quality, testable code and contribute to our continuous integration and deployment pipelines.
Infrastructure development
- Design and optimise reliable CI/CD pipelines, resilience, observability and security within AWS (i.e. CDK, Terraform) utilising workflows such as Github Actions, GitLab CI for example
- Manage AWS resources and containerised applications deployments via Docker
- Build and maintain a scalable infrastructure utilising Terraform (CDK within AWS)

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
