Senior Software Engineer

Polaron, a promising spin-out from Imperial College London, is seeking a Senior Software Engineer to join their team of nine. The company sits at the intersection of AI and materials science, building cutting-edge solutions for the materials of the future. They're developing a cloud-based SaaS product that enables materials engineers to leverage state-of-the-art image-based AI through an intuitive interface.

The role offers significant autonomy and influence over the platform's development, focusing on challenging technical problems like scaling canvas-based image processing to handle 10k+ resolution images and managing GPU cluster autoscaling. You'll be working across the full technology stack, from optimizing the React frontend to managing AWS infrastructure with Terraform.

The position requires 5+ years of product-focused software engineering experience, strong technical communication skills, and expertise in statically typed programming languages. The company operates primarily from their East London office, with a hybrid work arrangement (4 days office, 1 day remote), though they're flexible to individual needs.

Benefits include competitive salary (£85,000-130,000), equity in a fast-growing company, 27 days holiday, gym membership, and a modern office in Shoreditch Exchange Hoxton with free barista coffee. The interview process is thorough but fair, including an initial video call, technical pairing exercise, and a paid trial day for top candidates.

This is an excellent opportunity for a senior engineer who wants to make a significant impact in a growing startup that's applying AI to solve real-world materials science challenges. The role combines technical complexity with product development, offering a chance to shape the future of materials engineering tools.
