Responsibilities
- Contribute to software development across multiple projects and languages
- Maintain existing systems and implement new features in a full-stack capacity
- Help translate product and business workflow requirements into practical software solutions
- Support prototyping of new products and integrations, including reference implementations and UML-based integration mappings
- Create and maintain clear User Guides, API documentation, and implementation documentation
- Write unit, functional, and automated tests with guidance from senior engineers
- Use AI tools responsibly to accelerate learning, coding, debugging, documentation, and test creation, and validate everything they produce

- Follow the concepts of an agile process and contribute to planning, delivery, and continuous improvement
- Communicate clearly, raise risks early, and collaborate with teammates across engineering and product
Skills
- Working knowledge of software development fundamentals: data structures, complexity, state, and how a request moves from a browser to a database and back
- Experience with, or demonstrated ability to learn, TypeScript and full-stack web development
- Familiarity with Git and the core concepts of pull requests, merging, branching and code review
- A decent level of maturity with AI coding tools: you have used them on in personal or open source projects, you have been burned by them at least once, and you can describe what you check before you trust the output
- The ability to work independently on defined tasks while asking for help when appropriate, and the judgment to tell the difference
- Scala and functional programming are valuable but not required
- The expectation is that it can be delivered at a professional level
- Attention to detail and the ability to spot ambiguities
- Proficient managing your time and accountable for your actions

- Able to explain what you built and why to a senior engineer and to a business counterpart without hiding behind jargon
- Able to work with guidance, balance multiple activities, and meet deadlines, and to take instruction and turn it into shipped code without needing it repeated
- Operating with integrity
- Considerate of who's in the room and who needs to be in the room
- Taking notes in meetings for yourself and being personally organized
- Being able to say what you know, what you don't, and what you'd need to find out
- A growing sense of risk awareness: knowing when a change is routine and when it touches money
- Always learning new things
- Dedication to professionalism in all settings
- Receptive in code reviews: treating feedback as the fastest way to get better, and learning to give it constructively in return
- You value preparation: you research potential solutions to a problem (search the codebase, read the docs, try the obvious thing) before escalating it to the wider team
- Building backend or full-stack applications with Node.js and TypeScript is directly relevant
- Experience with React
- Any demonstrable real world products, or prior professional experience
