Applied SI Software Engineer, Factory Software

About the role

Applied SI Software Engineer, Factory Software | Tesla (Engineering & Information Technology)

Location: Fremont, California | Req ID: 274956 | Job Type: Full-time

What to Expect

We are seeking an Applied SI Software Engineer to join a small, high-performing team building SI agents that work alongside the people who run our factories. You will design, build, and ship production agents that reason over real manufacturing data and take action on it, supporting the many different roles across the factory that keep production running. You will own features end to end, from understanding the manufacturing problem through deploying a reliable service that people depend on during their shift.

The core challenge of the role is developing a deep understanding of the domain: how a process actually works, where the source of truth for the data lives, and what a good answer looks like to the person asking. The most rewarding part is seeing the impact: agents that save people time, help them make better decisions, and move the work forward faster.

You will work across modern programming languages, database systems, agent frameworks, and LLMs, and you will be expected to have strong software engineering fundamentals and the judgment to know when an agent's answer is trustworthy. Strong communication skills and a collaborative, feedback-driven mindset are essential, because building these agents means working closely with the manufacturing experts whose work they support.

What You'll Do

• Design, build, and ship production SI agents that help manufacturing engineers diagnose, decide, and act on the factory floor
• Develop deep domain understanding of the manufacturing processes each agent supports, and find the authoritative truth source for every data input
• Build the harness around the model, including tool definitions, retrieval, context assembly, and guardrails, so agents produce trustworthy, verifiable answers
• Write and iterate on prompts and tool instructions that make agents behave reliably
• Evaluate agent behavior rigorously by building eval sets and automated graders that measure answer quality and catch regressions before they ship
• Integrate agents with real manufacturing data systems including SQL and columnar databases, message streams, and live equipment interfaces
• Lead projects end to end, from gathering requirements with domain experts through architecture, implementation, testing, and production deployment
• Collaborate closely with manufacturing engineers and product partners to ensure each agent solves the real problem and earns user trust
• Maintain high engineering standards across version control, code review, CI/CD, monitoring, and logging for the services engineers rely on during their shift

What You'll Bring

• Strong software engineering fundamentals and a track record of shipping and maintaining production systems
• Proficiency in one or more modern languages such as Go, Python, C#, or JavaScript, including front-end frameworks such as React or Angular, with the ability to pick up others as the work demands
• Experience with SQL databases such as Postgres or MySQL, and familiarity with columnar stores such as ClickHouse and streaming systems such as Kafka
• Hands-on experience building agents with a modern agent development framework such as Google ADK or LangGraph
• Practical experience working with LLMs, including prompt engineering, harness engineering, and retrieval-augmented generation (RAG)
• The curiosity and persistence to develop deep domain understanding and to find the truth source of data rather than assuming it
• Sound judgment for evaluating when an agent's output is correct and trustworthy, and the rigor to measure it
• Strong communication skills and the ability to give and receive technical feedback in a collaborative environment
• Proficiency in rigorous software development practices including version control, code reviews, CI/CD pipelines, monitoring, and logging
• Bachelor's Degree in Computer Science, or related or equivalent experience
