Do you love crafting beautiful and functional customer experiences? Want to work on interesting technical problems around integrations and payments? Do you have a passion for Elixir and functional programming with a focus on building large, complex systems at scale? Peek is looking for a Senior Backend Engineer. The ideal candidate has 5+ years of development experience with Elixir, experience working with GraphQL APIs, MySQL, and familiarity with messaging queues such as RabbitMQ. In this role you will have the opportunity to take ownership of critical product areas and use AI tools as a force multiplier on top of your strong fundamentals.
Our engineering group works on several different products and systems: our Peek Pro operations management suite, embeddable scheduling & booking flows, and custom development services for our enterprise customers. This role will primarily focus on Connectivity via third party integrations and the Peek Pro “App Store”, and secondarily focus on payments-related initiatives.
We’re hiring a Senior Backend Engineer who works AI-first. That means you treat AI as a core part of how you build software and break down ambiguous problems, including delegating tasks to agents, reviewing their work critically, and course-correcting when things go sideways. You'll design and operate complex agent orchestration systems, develop patterns for human-agent collaboration, and ship real product features primarily through agent-assisted development in collaboration with human colleagues.
We work collaboratively, move fast, and value technical quality. If you are excited about the challenge of building an incredible product while working alongside a great engineering team, we’d love to hear from you!
What we’re looking for
Strong backend fundamentals in Elixir: API design, data modeling, SQL, service reliability, and debugging production issues.
Emphasis on creating scalable and reliable backend systems that integrate seamlessly with multiple services and products with an attention to high-quality code.
A drive for exploring and leading new approaches to complex problems via collaboration with multiple stakeholders across Product, Design, and Engineering, particularly amongst one’s peers.
Adaptability to the changing tech industry: demonstrated daily use of AI coding tools (Claude Code, Codex, Cursor or equivalent) in a production engineering workflow.
Ability to evaluate AI-generated code critically: you catch logic errors, identify security issues, assess maintainability, and own what gets merged regardless of how it was written.
Strong system design instincts: you think about tradeoffs, edge cases, and what happens when things scale or fail.
Clear and empathetic communicator: you flag when a spec has holes, you can articulate why you made a technical choice, you enjoy collaboration and seek to understand different perspectives, and you are constructive in any disagreements.
Self-motivation and ownership: you will push your work forward without prompting and look for ways to unblock yourself and the team on business priorities; you enjoy ownership over your work and seeing code through from conception to production.
Skills you already have A passion for Elixir and functional programming 5+ years of professional development using Elixir Solid coding practices including peer code reviews, unit testing, continuous integration, TDD, etc.
Experience with relational and/or non-relational databases Experience with microservices Strong understanding of AI tools and ability to identify pitfalls and course correct AI-generated code based on deep knowledge of the fundamentals of building production software Nice to haves
