Serves as in-house counsel for corporate finance, M&A, strategic investments, employee liquidity programs, equity administration, and commercial transactions. Leads financings and acquisitions from term sheet through closing, manages diligence and Board materials, advises on real estate and supplier agreements, and provides practical corporate guidance to executives and internal teams. The role also supports national security reviews, government contract diligence, and post-closing integration within a venture-backed defense technology company.

Own and mature the company’s intellectual property strategy across patents, trade secrets, software, data, trademarks, licensing, and open-source compliance. Manage IP portfolios, invention processes, agreements, employee IP obligations, and government data-rights matters. Advise technical and business teams on ownership, licensing, export controls, and risk. Support broader corporate legal work, including commercial contracts, transactions, financing, and legal-process improvements.

Designs and analyzes space missions, including rendezvous, proximity operations, and constellation performance. Builds simulation and modeling tools, conducts orbital mechanics and Monte Carlo analyses, optimizes spacecraft maneuvers, and supports system architecture decisions. Oversees mission-system integration, verification, testing, real-time mission support, and pre- and post-flight analyses. Collaborates with subsystem teams and stakeholders to assess performance, reliability, safety, risks, and mission success.

Architects and manages enterprise security engineering, threat detection, vulnerability assessment, security hardening, incident response, and security policies across cloud, on-premises, and SaaS environments. The role monitors security logs, supports compliance, advises on vendors and implementations, integrates security into the development lifecycle, and participates in on-call and change management activities.

Develop and test low-level flight software for spacecraft computers, integrate GNC algorithms, maintain command and telemetry databases, support spacecraft command sequencing, build subsystem simulators, and create device drivers and communications libraries. The role requires embedded RTOS, safety-critical systems, hardware protocols, C/C++, Python, and eligibility for TS/SCI clearance. This is an onsite position near Denver or Long Beach.

Develop and test flight software for spacecraft computers, integrate GNC algorithms, maintain command telemetry databases, and build simulators, device drivers, and communications libraries. The role includes spacecraft command scripting, ground-software collaboration, code reviews, and flight-software architecture work. Candidates need low-level firmware and safety-critical systems experience, embedded RTOS knowledge, C/C++ proficiency, and familiarity with hardware and networking protocols. This is an onsite position near Denver or Long Beach and requires the ability to maintain or obtain TS/SCI clearance.

Develop high-fidelity spacecraft simulation software in modern C++ and Python. Build multi-physics models covering spacecraft dynamics, thermal systems, attitude control, propulsion, power, sensors, and actuators. Implement solver architectures and time-stepping algorithms for real-time and faster-than-real-time simulation, maintain multi-language APIs, collaborate with engineering teams, and participate in code reviews and planning.

Leads and grows a team of modeling and simulation engineers developing high-fidelity physics-based models and digital twins for spacecraft design, testing, and operations. Provides technical oversight of modeling architecture, validation, and integration; owns the team roadmap; coordinates cross-functional delivery; manages hiring, performance, development, and team culture; and translates organizational strategy into execution.
