Senior Software Engineer, Simulation Tooling

About Mytra:

We’re creating an entirely new way to solve the most ubiquitous problem in industry - moving and storing material. We’re applying robotics and distributed software to create a new class of product for this $1T market. We’re focused on the supply chain industry first. The industry is in a massive bind with the continued growth of e-commerce, sharp rise in costs, and supply chain disruptions. What has been a “sleepy” industry for decades is now at the epicenter of sustaining the global economy.

Mytra’s Software team is looking for a senior software engineer to develop and scale the core backend systems that power our simulation and system validation environments. This role is ideal for someone who thrives in developing high-performance Python systems beyond traditional API development — working on multi-threaded processes, simulation environments, and backend infrastructure that bridges the gap between real-world robotics and virtual environments.

In this role you will collaborate closely with simulation engineers and other cross-functional teams across software, firmware, and robotics to develop performant, flexible, and scalable simulation tools, optimize performance, and ensure system reliability. Your work will directly impact the fidelity, scalability, and speed of Mytra’s simulation ecosystem by enabling rapid experimentation, system validation, and “what-if” scenario analysis.

Responsibilities:

• Design, build, and maintain backend systems for large-scale simulation and system validation environments
• Develop multi-threaded and process-driven Python applications to support high-performance simulation workloads and distributed processes
• Directly partner with simulation engineers, helping to integrate physical models, task schedules, and robot behaviors into scalable and extensible simulation services
• Collaborate with robotics, firmware, and infrastructure teams to ensure simulation fidelity and integration with real-world systems
• Lead the development of core simulation SDKs and reusable Python modules for internal use
• Build automated validation and test harnesses for continuous system performance evaluation
• Monitor, optimize, and scale simulation services across distributed or containerized environments
• Mentor other engineers and contribute to overall engineering best practices at Mytra
• Participate in design reviews, system architecture discussions, and performance tuning sessions

• 5+ years of industry experience
• Strong proficiency with systems-level development including multi-threading, multiprocessing, and system process management
• Experience in Python
• Experience building and maintaining long-running backend services or distributed systems
• Experience with testing frameworks and continuous integration pipelines (unit, integration, regression)
• Strong problem-solving and debugging skills, with attention to performance and reliability
• Excellent collaboration and communication skills

Nice to Have:

• Familiarity with containerization and orchestration (e.g., Docker, Kubernetes)
• Experience developing SDKs, simulation frameworks, or internal developer tools
• Familiarity with SimPy or other discrete-event simulation libraries
• Background in warehouse operations, system simulation, system validation, or software-in-the-loop (SIL) environments
• Experience with cloud infrastructure (GCP, AWS, or Azure)
• Exposure to robotics systems or embedded software environments
• If not Python, C++, Rust or Go are equivalents

A Final Note:

If this role excites you, we encourage you to apply — even if you don’t check every box. At Mytra, we build bots, but we hire humans. We value thoughtful challengers who communicate with clarity and respect, and we’re lifelong learners committed to getting better every day. We move fast, learn faster, and show up for each other under pressure. The best outcomes come from diverse perspectives working together to build something meaningful and built to last.

Benefits Include:

• Competitive compensation and equity grants at a high-growth company backed by top-tier VCs
• Fully subsidized health coverage, including medical (baseline plans), dental, and vision for employees and dependents
• 401(k) plans and employer-subsidized life insurance
• Fully subsidized lunch and snacks at HQ—we eat and share stories together at the “long” table
• Generous PTO and company-paid holidays, including one week over the winter break so everyone can recharge together
• Voluntary pet insurance, voluntary life insurance, Accident, Critical Illness, and Hospital Indemnity
• Fully subsidized tax advisory services and education to help you understand your equity
• Commuter benefits, including a up to $150 monthly commuter benefit
• Lively, modern combined office and lab space where we rapidly iterate through design, build, and test phases
• Fully equipped onsite gym and showers at headquarters
