Full Stack Engineer
Wintermute, London
What you need
- 5+ years of software development experience across both backend and frontend.
- Strong backend engineering skills, with Go and/or Python preferred; comfortable designing and implementing services, REST/WebSocket APIs and their data models.
- Solid working knowledge of the frontend stack: JavaScript and TypeScript, the Node.js/npm ecosystem, and a modern framework — React.js ideally, though experience with a comparable one is fine (please feel free to share any available examples of applications you built).
- Experience in client-facing financial or other professional services products is preferred but not mandatory (please mention products you worked on and their intended target users); fintech or crypto domain experience is a plus.
- Good understanding of the infrastructure applications run on: CDN, Cloudflare or similar, web servers, containers, CI/CD, plus basic monitoring and logging.
- Hands-on experience with a major cloud provider, AWS preferred (e.g. EC2/ECS, S3, IAM, VPC networking, load balancers); infrastructure-as-code such as Terraform is a plus.
- Working knowledge of relational databases and caching, including schema design and writing efficient queries.
