Do you jump with excitement at the opportunity to identify trends and provide unique business solutions? Do you want to join a team where learning about a new technology or solution is part of our work every day?

The Industry Solutions Engineering (ISE) team is a global engineering organization that works side‑by‑side with customers, on a per‑project basis, to collaboratively innovate custom solutions to solve their challenging business problems; from inception to production. We develop broadly applicable, high‑impact solution patterns and open‑source software assets in collaboration with Microsoft product teams, partners, and open‑source communities. This role will be working in a delivery studio focusing on customers from the Retail & Consumer Goods and Telecoms, Media & Gaming industries.

Working alongside engineers and technical program managers, you'll architect end‑to‑end AI solutions, develop production‑ready ML pipelines, and contribute to scalable infrastructure serving millions of users while implementing MLOps practices at enterprise scale.

Our team prides itself on embracing a growth mindset, innovating to empower others, and collaborating to realize our shared goals.
