About Handshake AI

Human data is the core infrastructure to AI advancement. Frontier AI labs currently improve model capabilities with various data-intensive post-training techniques. We believe that data spend for AI training will increase by 3-5x in the next few years and continue for much longer as models take on new domains. Handshake AI supports all of the frontier AI labs, working on their most complex data at the largest scale.

About the Role

As a Senior Forward Deployed Engineer, you'll serve as a technical leader at the intersection of our engineering organization and our most strategic customers, including leading AI labs. You'll own the end-to-end lifecycle of high-impact deployments-from scoping complex technical requirements to architecting, building, and scaling solutions that directly improve customer workflows and model performance. You'll operate across the stack in highly ambiguous, fast-changing environments, and your judgment will shape how we approach our most critical partnerships.

This is a unique opportunity to combine deep technical leadership with direct customer engagement-driving not just the "what" and the "how," but setting the standard for how Handshake delivers at the highest level.

Location: San Francisco, CA | 5 days/week in-office

• Partner with AI labs and cross-functional stakeholders to deeply understand technical challenges, translate ambiguous requirements into actionable engineering plans, and drive alignment across teams.
• Own the design, architecture, and delivery of tailored, production-grade solutions for complex, high-impact customer needs-often with minimal precedent or existing playbooks.
• Mentor and uplevel other engineers through code reviews, architectural guidance, and establishing best practices for forward-deployed work.
• Make key architectural decisions around reliability, scalability, and security, and set the technical direction for repeatable deployment patterns.
• Rapidly prototype, test, and iterate on tools in response to real-time feedback, balancing speed of delivery with long-term maintainability.
• Create and maintain technical playbooks, documentation, and frameworks that enable the team to scale deployments efficiently.

Desired Capabilities

• 5+ years of professional software engineering experience, with meaningful time spent in customer-facing, solutions-oriented, or forward-deployed roles.
• Strong proficiency with ReactJS and TypeScript, with a high bar for code quality, usability, and accessibility.
• Deep understanding of relational databases (e.g., PostgreSQL), data modeling, and system design.
• Experience with cloud infrastructure (AWS, GCP), deployment pipelines, and production operations at scale.
• Demonstrated ability to lead technical projects end-to-end in ambiguous environments with shifting requirements.
• Excellent communication and stakeholder management skills, with the ability to build trust with both technical and non-technical audiences.
• Track record of mentoring engineers and raising the bar on engineering practices within a team.

Extra Credit

• Experience architecting and delivering production systems for LLMs or other AI-powered products in real-world, customer-facing environments.
• Background in building or contributing to component libraries, design systems, or reusable deployment frameworks.
• Proven experience with performance optimization and scaling of full-stack applications under real-world constraints and high-traffic conditions.
• Prior experience in a forward-deployed, solutions engineering, or technical consulting role at a high-growth company.
