About Stell

Stell helps aerospace and defense companies spend more time building and less time managing spreadsheets/PDFs for each product’s compliance to customer, technical, and regulatory requirements.

The Stell platform is digitizing requirements with a “living Specification” workflow.

Core product features:

  • Ingest and parse 100 page PDFs of technical system requirements and decompose them using a large language model into a block based document editor and a matrix that highlights the requirements statements
  • Matrix view allows engineers to tag, filter, and search requirements quickly - making navigating thousands of requirements on a complex program 10X faster
  • Matrix view allows multi relationship linking to other requirements in the program or system - so that engineers know when a customer changes a requirement how it affects other documents and design statements in their system down to the gritty part processing details
  • Matrix view allows linking to test results, research, and inspection records - allowing engineers to create an easy to view file which shows them how much of their engineering is complete and ready to be sent to a customer vs. the requirements for the system
  • Stell uses LLMs to automatically compare new versions of published specifications, and to compare interfacing documents to find risks and conflicting requirements. This is critical for developing new system of systems for space, naval, and energy applications with multiple hardware devices, softwares, and firmwares teaming for a solution.
  • Stell uses LLMs to find and highlight risks in the system development based on historical test results, change requests, and deviations and waivers. Stell is a co-pilot to engineering decision making.



In the Product Manager role you will:
  • Work directly with the CEO/CTO to ensure strategic direction of product. You will develop weekly and monthly documentation to highlight product priorities to the team.
  • Work directly with customers at Aerospace & Defense companies to develop strategy, PRDs, and review new features.
  • You will own velocity on core product - Review and give feedback on Figma of designs and cut Linear tickets for engineering. Ensure maximum clarity is found before code is written.
  • Plan each weekly cycle with engineering. You ensure planned work is achievable, ambitious, and the most critical to customer outcomes. You ensure wins and progress on product are celebrated and shown daily through mini-demos, videos, and customer feedback.
  • Document and communicate to team on strategy and plan for next 4 weeks and 3 months. Maintain rough schedule in Linear.
  • Write PRDs to assist engineering and design in developing larger projects.
  • Test new features as they come out and ensure they will be ready for customers. You advocate heavily for customer experience on speed, delight, and reliability.


This may be a good fit if you:
  • Have 2 years of experience as a product manager building B2B software products.
  • Are an obessive Linear or Jira user. You are extremely organized and meticulous with processes and documentation.
  • You have worked as a PM at an early stage company (founding to Series B).
  • You are extremely positive and able to see potential solutions amidst competing signals. You can rally others to your solution and communicate effectively.
  • You are opinionated about processes but are flexible to always be iterating and changing.
  • Have a background as a software engineer prior to working as a product manager.
