Python Backend Engineer - 3D / Visualization / API / Software (On-site)
Lead engineer job in San Jose, CA
A pioneering and well-funded AI company is seeking a talented Python Backend Engineer to build the core infrastructure for its revolutionary autonomous systems. This is a unique opportunity to join an innovative team at the forefront of engineering and artificial intelligence, creating a new category of software that will redefine how complex products in sectors like aerospace, automotive, and advanced manufacturing are designed and developed.
Why Join?
Build the Future of Engineering: This isn't just another backend role. Your work will directly shape how next-generation rockets, cars, and aircraft are designed, fundamentally changing the engineering landscape.
Solve Unprecedented Technical Puzzles: Tackle unique challenges in building the infrastructure for autonomous AI agents, including simulation orchestration, multi-agent coordination, and scalable model serving.
Shape a Foundational Platform: As a critical member of a pioneering team, you will have a significant impact on the technical direction and core architecture of an entirely new category of software.
Join a High-Impact Team: Work in a collaborative, fast-paced environment where your expertise is valued, and you have end-to-end ownership of critical systems.
Compensation & Location: Base salary of up to $210,000 + equity + benefits, while working on-site with the team in a modern office in downtown San Francisco.
The Role
As a Python Backend Engineer, you will be instrumental in constructing the infrastructure that underpins these autonomous engineering agents. Your responsibilities will span model serving, simulation orchestration, multi-agent coordination, and the development of robust, developer-facing APIs. This position is critical for delivering the fast, reliable, and scalable systems that professional engineers will trust and depend on in high-stakes production environments.
You will:
Own and build the core backend infrastructure for the autonomous AI agents, focusing on scalability, model serving, and multi-agent orchestration.
Design and maintain robust APIs while integrating essential third-party tools like CAD software and simulation backends into the core platform.
Develop backend services to process and serve complex 3D visualizations from simulation and geometric data.
Collaborate across ML, frontend, and simulation teams to shape the product and engage directly with early customers to drive infrastructure needs.
Make foundational architectural decisions that will define the technical future and scalability of the entire platform.
The Essential Requirements
Strong backend software engineering experience, with a primary focus on Python.
Proven experience in designing, building, and maintaining production-level APIs (FastAPI preferred but Flask and Django also considered).
Experience with 3D visualization libraries or tools such as PyVista, ParaView, or VTK.
Excellent systems-thinking skills and the ability to reason about the interactions between compute, data, and models.
Experience working in fast-paced environments where end-to-end ownership and proactivity are essential.
Exceptional communication and collaboration abilities.
What Will Make You Stand Out
Experience integrating with scientific or engineering software (such as CAD, FEA, or CFD tools).
Exposure to agent frameworks, workflow orchestration engines, or distributed systems.
Familiarity with model serving frameworks (e.g., TorchServe, Triton) or simulation backends.
Previous experience building developer-focused tools or working in high-trust, customer-facing technical roles.
