Lead offering-level architecture across ground, space, software, and hardware. Define interfaces, requirements, capability allocation, CONOPS, and ICDs. Coordinate cross-functional teams, drive architecture decisions, and ensure scalable, reusable solutions and customer-facing ground tooling.
Wanna join the adventure?
Loft Orbital builds a space infrastructure providing a fast & simple path to orbit. Using different flight proven buses, we design, integrate and operate spacecraft to fly physical or virtual customer payloads. We handle entire missions end to end, significantly reducing the lead-time and risk of a traditional space mission.
As a Senior Product Systems Engineer at Loft, you will own the architecture of our overall offering — the layer that sits above any single implementation team and brings coherence across ground, space, software, and hardware. You will define how Loft's platform is structured, how capabilities are allocated across segments, and how customers, third-party software, and Loft's own stack interact.
This is not a role about executing within a defined system. It is about shaping the system itself— making cross-cutting architecture decisions, defining interfaces and requirements at the offering level, and ensuring the ground processing chain and customer-facing tooling evolve in a way that is coherent, reusable, and product-relevant. You will work closely with engineering, product, and operations teams across sites, and your work will directly influence how Loft's offering is built, exposed, and scaled.
About this role:
- Help define the general architecture of Loft’s offering across ground and space
- Support capability allocation across hardware, software, ground, flight, Loft-owned components, and external components
- Ensure the ground processing chain is defined and evolved as a coherent part of the offering
- Help shape ground software tools and interfaces as the main entry point for customers
- Clarify the interaction model between OBSW, ground software, customer software, third-party software, and Loft’s stack
- Help define, organize, and maintain requirements, interfaces, and architectural boundaries for offering-level topics
- Coordinate architecture discussions and drive alignment between product intent, system architecture, and implementation realities across teams
- Contribute to CONOPS, ICDs, architecture notes, trade studies, and related technical documentation
- Help ensure solutions are reusable, scalable, and understandable rather than tailored only to one mission
- Support architecture reviews and technical decision-making on cross-cutting topics
Must Haves:
- Strong systems engineering background in complex technical products spanning software and hardware
- Experience working at the boundary between architecture definition, requirements structuring, and engineering implementation
- Ability to structure complex systems into clear capabilities, interfaces, requirements, and responsibilities
- Strong understanding of software-heavy systems, including distributed components, APIs, processing chains, and integration patterns
- Ability to coordinate cross-functional technical work across several teams without relying on direct authority
- Strong communication and documentation skills, including the ability to turn technical ambiguity into a clear framework for decisions and execution
- Sound engineering judgment on the right level of rigor, abstraction, and specification for a growing organization
Nice to Haves:
- Experience with space systems, including ground segment tooling, onboard software, or customer-facing technical platforms
- Experience defining integration models involving customer-owned or third-party software
- Experience with architecture trade studies, capability allocation, and system-level interface management
- Familiarity with CONOPS, ICDs, and other architecture or interface documentation methods
- Experience with onboard data processing and cloud-based ground software
- Experience in international and cross-site engineering collaboration

*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.
Who We Are
Loft: Space Made Simple.
Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.
We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.
With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
