Job Description
About the job *Role Overview * We are seeking a Principal Engineer who sets technical direction by example. An architect who still writes code, reviews code, and makes the engineers around them better. This is not a role for someone who has moved away from the keyboard. It is a role for an engineer who has shipped production systems at scale, knows the million small details that separate a demo from a product customers depend on. You will set architectural direction across our products and platforms. You will partner with our existing engineers, challenge their thinking, and ensure the systems we build are the best-architected they can be — simple, modular, resilient, and built to evolve. You will spend real time in code reviews, in design documents, and at the keyboard yourself. And you will invest heavily in the engineers around you: the strength of the team you grow is the truest measure of your success in this role. You understand that AI has fundamentally changed the job of a Principal Engineer — for the better. The best practitioners today ship more, review more, prototype more, and mentor more because they treat AI as an amplifier, not a threat. You will bring that mindset to DeepRunner, and you will help the rest of the engineering organization get better at it.
Set architectural direction across our products and platforms. Drive the decisions that matter: service boundaries, data models, API contracts, and the shape of the systems we will still be living with in three years. Write code. Ship code. Review code. Your tenure here will be measured in commits and architecture decisions, not slide decks. Raise the bar on code reviews. Every review is a teaching moment. Define the standards, enforce them, and explain the “why” so they stick. Mentor and grow the engineers around you. Develop your peers and your juniors into stronger engineers. This is a core responsibility of the role, not a side activity. Ship production software with full production responsibility: edge cases, failure modes, backwards compatibility, migrations, observability hooks. Always insist on the highest standards spanning architecture, development, deployment, operational excellence. Use AI in your daily work the way a modern Principal Engineer should: to prototype faster, review more code, explore more alternatives, and multiply your own reach.
DeepRunner AI is building the future of SMB software. Our flagship product combines modern business platforms with AI‑powered automation to help SMBs operate more efficiently. We believe AI should empower human workers by handling repetitive tasks so people can focus on strategic thinking, creativity, and complex problem‑solving. We are a fast‑growing startup with teams across Silicon Valley, Athens, and Delhi. Our culture is rooted in #Day1 and #OneTeam principles.
