Role
Who you are

- You excel in high-impact, high-responsibility environments and take ownership of complex systems
- You have deep experience in ML engineering, with applied knowledge of deep learning, recommendation systems, reinforcement learning, or agentic AI
- You thrive in ambiguous, pioneering spaces, able to chart paths where few have gone before

- We’re seeking a Staff Machine Learning Engineer to own the design, development, and scaling of ML systems powering next-generation payment flows, recommendation engines, and agentic commerce features
- This is a full ownership, all-in role: you’ll define architectures, implement models, and optimize real-world systems that handle complex financial decisions at scale
- Build and deploy state-of-the-art ML models for personalized recommendations, fraud detection, transaction automation, and user behavior prediction
- Architect and scale ML systems powering agentic commerce workflows, including autonomous decision-making and checkout automation
- Lead technical initiatives, guiding other engineers and influencing the roadmap for core AI infrastructure
- Collaborate with product, design, and research teams to turn cutting-edge ML ideas into real-world features
- Experiment with novel algorithms and architectures, staying ahead in fast-evolving payments and AI domains
- Own projects end-to-end, from conception through deployment and ongoing optimization
Our take
Designed to replace existing checkout models and make buying on any device easy and safe, Bolt provides a one-click checkout solution. Its online shopping software is utilized by companies like Brooks Brothers and Forever 21. As well as supporting all major card providers and alternative payment methods like PayPal, customers also don't need a username or password. This reduces cart abandonment and increases merchant conversion rates.
The company has seen impressive growth, annually processing more than $1 billion in retail transactions across its 300+ retailers. While Bolt has won the race against Google, who tried, and failed with Google Checkout, there are other 'one-click' competitors to watch out for, including Square, which has over 30 million monthly active users.
