Sr. Software Engineer - Simulation / Support

About the role

What we’re doing isn’t easy, but nothing worth doing ever is.

We envision a future powered by robots that work seamlessly with human teams. At Diligent Robotics, we build artificial intelligence that enables service robots to collaborate with people and adapt to dynamic, human-filled environments.

Diligent is one of the only companies in the world operating a production fleet of mobile manipulation robots in real environments . Every day, our robots work alongside hospital staff, generating the real-world data needed to advance the next generation of Physical AI. If you’re excited about solving the hardest problems in robotics, where simulation meets real-world deployment, this is the job for you.

As a Senior Software Engineer – Simulation / Support , you will accelerate the effectiveness of our engineering organization. This hybrid role spans developer tooling, software support and triage, and simulation infrastructure. You will help engineers build better software, faster, while strengthening the reliability and debuggability of our robotics stack in production.

You will develop state-of-the-art infrastructure to test and validate Physical AI models, and help bridge the gap between simulation and reality by improving synthetic data and scenario generation with real-world data from our growing fleet of operational robots.

Responsibilities

Design and build tools that improve productivity and debugging across the robotics software stack

Develop and maintain simulation infrastructure used for testing autonomy, navigation, perception, manipulation and system level behaviors

Partner with autonomy, perception, platform, and infrastructure teams to integrate simulation into CI pipelines and validation workflows

Create reproducible test harnesses and simulation scenarios that mirror real world operational edge cases found in our customer environments

Support release readiness by strengthening automated validation, regression testing, and scenario based simulation coverage

Contribute to architecture decisions that improve modularity, testability, and long term maintainability of the codebase

Evaluate and integrate third party simulation frameworks or build custom simulation tooling as needed

Mentor engineers on best practices in testing, debugging, observability, and system design
