Software Engineer

The Role

Raydar is recruiting for this role on behalf of our client. Take responsibility for delivering customer-facing software from design through production at an early-stage company. The work spans backend data processing and low-latency automated decision systems, with frequent direct contact with customers during pilots and rollouts. You will also help set technical direction alongside a very small engineering group.

What You'll Do

• Take full ownership of new capabilities, from initial design to live release for large business customers within a few weeks.
• Build backend pipelines that collect and process large volumes of varied telemetry from many sources.
• Create real-time systems that detect problems and apply rules automatically.
• Partner with customers during pilots and rollouts, sometimes releasing improvements while an engagement is still in progress.
• Train compact machine learning models that return quick judgments within strict latency limits.
• Stress-test models and automated agents with adversarial scenarios so weaknesses surface before customers encounter them.
• Contribute to platform architecture and technical decisions with a small founding group.

What We're Looking For

• 0 to 4 years of engineering experience, internships included.
• A record of delivering production software.
• Time spent at startups recognized for strong engineering talent.
• Solid backend and systems fundamentals, such as large-scale distributed systems or infrastructure.
• Comfort with an intense, fast-moving environment that has little formal structure.
• Ability to work on-site in San Francisco.

Bonus Points

• Background in competitive programming.
• Hands-on machine learning experience, such as adapting or tuning models.
• Exposure to application security, adversarial testing or attacks on machine learning systems.
• Experience at a quantitative trading firm.
• Prior work embedded with customers or in a client-facing technical role.
• Degree from a highly ranked computer science program or equivalent.
