About Primordial Labs

Were building the next generation interface for commanding autonomous systems in the real world. Our core product, Anura, translates spoken or typed intent into structured actions across drones, sensors, and mission software—enabling faster, more intuitive control in high-stakes environments. We’re a distributed team of engineers, operators, and technologists focused on deploying reliable autonomy at the tactical edge.
We’re hiring a model-based systems engineer to capture how all of that fits together, and to build the model that will serve as the technical ground truth the entire company relies on.
You’ll model software-intensive systems: services, APIs, data flows, and deployments, plus the hardware and network interfaces at their edges. You’ll also map our architecture to the frameworks our partners and government programs use, and help shape how systems engineering works here.
Model the Software: Capture services, APIs, data flows, deployments, and internal software processes, plus the hardware and network interfaces at their edges.
Work Inside Engineering: Partner closely with software engineers, which means understanding how software is designed, built, tested, and released.
Contribute model content to design reviews, proposals, and prime deliverables.
Shape the Practice: Help define how systems engineering works here as the company grows.
Software-Fluent: You’re a systems engineer who understands modern software well enough to model it accurately, from microservices to CI/CD.
Owner of the Model: You treat the model as a living product, not a document that goes stale after the review.
Practice Builder: You want to help shape how systems engineering works at a growing company, not just follow an existing process.
Experience: 5+ years of systems engineering on software-intensive or networked systems, including 3+ years of hands-on MBSE, owning end-to-end model development and management.
MBSE: Expertise modeling in SysML (preferably v2) or a comparable language, covering structure, behavior, and interfaces.
Software Engineering: Strong understanding of software design, architecture, microservice and distributed systems, APIs, version control, CI/CD, and agile delivery, plus the ability to model internal software processes.
Experience defining hardware/software interfaces, such as ICDs, protocols, data links, radios, sensors, or embedded hosts.
Requirements engineering and verification traceability, especially in defense applications.
Clear writing, and the ability to explain technical architecture to non-engineers and user needs and desired behaviors to engineers.
Ability to obtain and maintain a US Security Clearance.
By day 90, you’ve modeled a real part of our system, and teams outside engineering have used your work.

Learn the product, the software architecture, and the teams. Model one subsystem’s software components and its hardware or partner interfaces, with its engineering owner. Map part of our architecture to a customer or government reference architecture, or deliver model content for a proposal, design review, or prime deliverable.

Please note that Permanent Residency (Green Card status) or visa sponsorship cannot satisfy these specific regulatory requirements.
