What We Are Looking For

\n

\n

We're looking for an exceptional Senior Software Engineer (Data and AI) to design, build, and ship agentic systems for our clients. This is a hands-on senior role: you'll set technical direction on client engagements, lead architecture and design decisions, and still write a lot of the code yourself across Python, TypeScript, and .NET. You'll own delivery end to end and make sure what you build stays reliable and maintainable once it's in a client's hands.

\n

\n

The tooling in this space is changing quickly and the standards are still settling. We'd like someone who keeps up with it, can tell the difference between what's ready for client work and what isn't, and can explain that judgment clearly to clients and to the rest of the team.

\n

\n

If you take ownership of your work, are a great communicator, and thrive in environments with changing requirements, this job is probably right up your alley. You'll work directly with client stakeholders to scope problems and shape solutions, and you'll help mentor and level up other engineers on the team. Our team includes network architects, cloud architects, software developers, and security engineers. You will work alongside experts with significant real-world experience on high-impact projects. We also provide many opportunities for growth and will cover the cost of relevant education and certification.
