Senior ML Engineer

About Quilter

At Quilter, we are helping electrical engineers save time and accomplish more by automating the tedious and time-consuming task of designing printed circuit boards (PCBs). Our small team is composed of experts in electrical engineering, electromagnetic simulation, ML/AI, and high-performance computing (HPC). We are inventing and leveraging novel techniques to solve the decades-old problem of automating circuit board design where today hundreds of billions of dollars are spent. We have raised $25 million in Series B funding from some of the very best and are charging full-speed toward our goal.

No matter where we come from, we're united by a common vision for the future and a core set of values we think will get us there:

Curiosity

Conviction

Rigor

We're looking for a Senior ML Engineer to join Quilter's Placer Team and help us build the AI that automates component placement on PCBs.

The Role

The Placer is responsible for automated component placement on PCBs. This role spans the full lifecycle: research, prototyping, productionization, and maintenance. You'll work across optimization, machine learning, and geometric deep learning on a hard, real-world combinatorial problem.

This is a fully distributed team. We expect high autonomy and high ownership.

What Youʼll Do

Own problems end-to-end from exploratory R&D through production-hardened, maintainable systems

Develop and extend GPU-accelerated code in PyTorch and CUDA C++

Work across a broad modeling landscape including RL, graph neural networks, black-box/classical optimization, and generative modeling

Formulate objectives, model constraints, and debug numerical behavior in the stack

Contribute to technical direction and research strategy alongside senior teammates

What Weʼre Looking For

5+ years of industry experience in ML, optimization, or a related field

Strong fundamentals in machine learning and optimization

Production PyTorch experience

Demonstrated ability to work across research and production codebases

Comfort operating with high autonomy in ambiguous problem spaces

Strong communication and collaboration skills

Preferred

5–7 years of industry experience (Staff-level appointment may be considered)

CUDA C++ experience

Background in any combination of: reinforcement learning, geometric deep learning, graph neural networks, multi-objective optimization, combinatorial optimization

Please note : We are an equal opportunity employer. At this time, we are focused on hiring primarily within the US, with occasional exception to accommodate exceptional talent.

What we offer:

Interesting and challenging work

Competitive salary and equity benefits

Health, dental, and vision insurance

Regular team events and offsites (~4x / year)

Unlimited paid time off

Paid parental leave
