Senior Software Engineer

## About the role EdgeTier is looking for a Senior Software Engineer who wants to do some of the best work of their career. This is a hands-on role within our backend team with real ownership. This means you'll be expected to operate independently from the start and hold yourself to a high standard. The way we build software is evolving. AI coding agents are part of our everyday workflow, and we're looking for someone who knows how to direct, review, and get the best out of those tools — not someone who treats them as a shortcut. We care about the quality of the output, not just the speed of it. This is a small, high-trust team. In this role, you'll find more autonomy, more impact, and more accountability than you would in a larger engineering org. If that energises you, read on. ## What you'll be doing - Translating product requirements into detailed technical specifications and owning delivery end-to-end from design through implementation, testing, and release. - Architecting changes to EdgeTier's core product including APIs, services, and databases. - Writing high quality and well structured Python code while holding a high standard in code reviews. - Directing and critically reviewing AI coding agent output to ensure quality. - Monitoring application performance and error logs. - Mentoring junior engineers. - Contributing to architectural decisions and using your voice and ideas to shape how we build EdgeTier. ## How your time breaks down (roughly) - Developing new features: 30% - Reviewing pull requests: 20% - Architecting changes: 15% - Bug fixes and feature maintenance: 10% - Team communication and meetings: 10% - Testing and releasing features: 5% - Performance monitoring and error logs: 5% - Developer tooling improvements: 5% ## What we're looking for in you Technical ability matters, but so does how you work. We want someone who leaves things in better shape than they found them. Someone pragmatic enough to know when to ship and disciplined enough to know when to refactor. This role will be challenging. If that excites you, this is the role for you. ## What you'll need - 6+ years of professional software development experience in a product, SaaS, or similar environment - Solid Python skills - SQL experience, ideally PostgreSQL - Experience working with data at scale in large datasets or high-volume systems - True end-to-end engineering experience: local development, deployment, debugging in production, ongoing maintenance - Strong communication skills. We want you to be able to explain complex technical problems clearly to non-technical stakeholders - Proven ability to work independently and manage your own time without close supervision - Hands-on experience with AI coding tools and agents. ## Useful but not essential - Flask, AWS, Pytest, GitHub Actions or similar CI/CD tooling, Terraform, experience writing or customising AI agents. - Start-up or scale-up experience: comfortable with ambiguity, a fast-moving environment, and doing what needs to be done ## What makes this role worth it You'll have genuine influence over how EdgeTier's engineering team develops, the chance to mentor others, and the space to do your best technical work. You won't be given a list of tasks to execute — you'll be given problems to solve, and trusted to solve them well. If you're motivated by the idea of building something excellent, and you hold yourself to a high standard, we'd like to hear from you. ## EdgeTier Company Values At EdgeTier, we're passionate about building a team of high performers who believe in our mission.
