Lead system-level validation for spacecraft platforms, focusing on software-test infrastructure integration. Guide V&V planning, remove blockers, mentor test engineers, improve HIL/SIL environments, and drive scalable, automated validation and release gates across cross-functional teams.
Wanna join the adventure?
We’re looking for a System Verification Architect to join our Operations team in Golden, CO. This is a senior, hands-on technical role focused on enabling fast, effective, and reliable system-level validation of Loft’s spacecraft platforms and products, with a particular focus on software and test infrastructure dependencies.
The ideal candidate is a strong technical generalist with deep experience in software-hardware integration, test infrastructure, and software verification methodologies, who can help guide cross-functional testing strategies across multiple teams, and act as a force multiplier for our test engineering and validation efforts.
This is a high-impact position working closely across teams such as Test Infrastructure, AIT (Assembly, Integration & Test), Systems Engineering, Software, and Mission Operations.
About the Role:
- Facilitate high-quality system-level validation for Loft’s missions, products, and programs—especially in areas where software and test infrastructure intersect.
- Collaborate with systems engineers to review and improve Verification & Validation (V&V) plans, ensuring complete coverage and realistic execution timelines.
- Identify and resolve blockers in validation campaigns—ranging from missing test hardware, gaps in infrastructure, or unclear software interfaces.
- Act as a technical mentor and subject matter expert, especially in areas related to Loft’s test infrastructure, software stack, and test planning processes.
- Drive continuous improvement in how we validate our hardware and software systems—from test plan development through execution and feedback.
- Propose and help implement processes, tools, and infrastructure that improve the scalability, repeatability, and efficiency of system validation.
- Review and guide V&V plans: Ensure our plans are thorough, executable, and account for software/test infra dependencies. Identify long lead risks or missing elements early.
- Raise the bar on test quality: Mentor test engineers, review test plans and procedures, promote automation and reusability, and participate in TRRs and related milestones.
- Resolve blockers: Be the go-to resource for resolving complex testing issues. Help debug bricked flight processors, uplift test benches, or validate firmware updates—whatever it takes to keep validation moving.
- Bridge silos: Work across departments to improve coordination between Product, Test Infrastructure, Software, and AIT. Share context, reduce redundancy, and push for alignment.
- Promote scalable testing: Advocate for architecture and tooling that support modular, reusable validation methods (e.g., "Lego block" approach to testing assets).
- Improve software release validation: Help define gates for feature releases that align with system-level validation needs. Map the software lifecycle to our hardware integration plans.
Must Haves:
- 7+ years of experience in software-hardware system integration or verification, especially in aerospace, automotive, or embedded systems domains.
- Strong background in software validation at the system level—not just unit tests.
- Hands-on experience with Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) test environments.
- Deep knowledge of how software functions across the stack—from firmware to embedded systems to ground applications.
- Strong Python skills and familiarity with scripting tools used in test automation.
- Experience working with networking fundamentals (TCP/IP, UDP, DNS, etc.) and understanding real-world communication between distributed systems.
- Familiarity with software release processes, agile methodologies, and cross-functional validation workflows.
- Able to troubleshoot hardware-software integration issues across a wide range of systems, from flight processors to test infrastructure.
- Excellent communication and collaboration skills. Can speak the language of both hardware and software teams.
Nice to Haves:
- Experience designing or validating complex HIL/SIL testbeds.
- Familiarity with Loft’s core products and software stack (e.g., HubKit, flight software, ground control systems).
- Prior experience in aerospace system validation (CubeSats, smallsats, or bus-level avionics).
- Ability to "tinker" and dive into test setups—wiring, scripting, log analysis, debugging, etc.
- Comfort working in ambiguity—able to identify gaps, create structure, and drive progress across teams.
Some of Our Awesome Benefits:
- 100% company-paid medical, dental, and vision insurance option for employees and dependents
- Flexible Spending (FSA) and Health Savings (HSA) Accounts offered with an employer contribution to the HSA
- 100% employer paid Life, AD&D, Short-Term, and Long-Term Disability insurance
- Flexible Time Off policy for vacation and sick leave, and 12 paid holidays
- 401(k) plan and equity options
- Daily catered lunches and snacks in office
- International exposure to our team in France
- Fully paid parental leave; 14 weeks for birthing parent and 10 weeks for non-birthing parent
- Carrot Fertility provides comprehensive, inclusive fertility healthcare and family-forming benefits with financial support
- Off-sites and many social events and celebrations
- Relocation assistance when applicable
*Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions. We strongly encourage you to apply, even if you don’t check all the boxes.
