Red Cell Partners is an incubation firm building and investing in rapidly scalable technology-led companies that are bringing revolutionary advancements to market in three distinct practice areas: healthcare, cyber, and national security. United by a shared sense of duty and deep belief in the power of innovation, Red Cell is developing powerful tools and solutions to address our Nation’s most pressing problems.
Co-founded in 2023 by Joe Laws and Grant Verstandig, Trase Systems is AI, Uncomplicated. Trase empowers enterprise leaders to harness the full potential of AI without the associated complexity and risks. We are an end-to-end solution for deploying, managing, and optimizing AI in the enterprise. Our platform specializes in bridging the “last mile” of AI adoption, unlocking AI's full potential while driving efficiency and significant cost savings. Trase is at the forefront of AI Agent innovation, topping the Hugging Face GAIA Leaderboard for Generalized AI Assistants, ahead of industry giants such as Google, Meta, Microsoft, and OpenAI. We are leveraging our cutting-edge technologies to develop mission-critical agentic applications in complex industries such as Healthcare, Oil & Gas, and National Security.
As a Senior or Staff Software Engineer, you'll build and own critical parts of Trase OS, the shared platform that powers Trase deployments in regulated environments. You'll work on the distributed systems and platform primitives connecting workflows, agents, tools, and product surfaces, with a particular focus on reliability, scalability, and correctness.
You'll take on technically ambiguous problems, design solutions, and drive them through production. This is a hands-on engineering role for someone who is comfortable going deep on distributed systems while helping other engineers make sound architectural decisions.
Clean abstractions and correctness-under-failure are critical because we operate long-lived agents in healthcare/defense environments where auditability and reliability are non-negotiable.
The level will reflect your experience and demonstrated scope. Staff-level candidates will be expected to lead architecture across teams, establish engineering standards, and mentor other engineers.
Trase OS is an orchestration-heavy system coordinating long-lived workflows, agents, and tools across multiple services and environments.
As the platform evolves, the primary risks shift from implementation to system design quality:
This role exists to:
You are designing systems where failure is the norm, not the exception, and correctness must be preserved across retries, restarts, and partial execution.
You must balance clean abstractions with real-world constraints (performance, security, multi-tenant environments).
Decisions made here become foundational primitives used across all products and teams.
The system must remain understandable and auditable, even as complexity and scale increase.
If you want to be on the cutting edge of technology, building AI solutions for the future, and are up for a challenge, let’s talk!
$180,000-240,000. This represents the typical salary range for this position based on experience, skills, and other factors.
Some travel to customers may be required.
We’re an Equal Opportunity Employer: You’ll receive consideration for employment without regard to race, sex, color, religion, sexual orientation, gender identity, national origin, protected veteran status, or on the basis of disability.
