Requirements

A minimum Bachelor’s Degree (or equivalent) in Computer Science, Engineering or related technical field
A minimum of 3 + years of non-internship full time professional software development experience
4+ years of experience with at least one software programming language
4+ years of experience in the full software development life cycle
Experience delivering large software projects or features in a production environment
Proficiency in at least one modern programming language (e.g., Python, Java, JavaScript, etc.)
We are looking for an engineer with a track record of building brand new products from scratch.
You have been using the latest AI software development techniques (ex: teams of AI Agents) and continuously look for new AI techniques that can improve your productivity.
You move fast , know how to balance innovation vs reuse, and deliver clear business results.
You’re reading and writing code across the tech stack (e.g., React Native, BFF/full-stack web, GraphQL, AI Agents, Computer Vision, Medical Device Integration, etc), and you use that fluency to coach, review, and set technical direction.
You think in terms of hypotheses, sample sizes, and decision rules, and you can run a dense A/B experimentation roadmap without sacrificing quality.
You enjoy leveling up a strong but more junior team through pairing, code reviews, design discussions, and clear written communication.
You think in terms of systems and business impact, not just tickets—you’re comfortable taking a problem from idea through launch, measurement, and iteration.
You create clear expectations, give direct feedback, and foster a culture where engineers can do the best work of their careers.
