Our space program is core to this mission. We are building and operating a weather observation constellation powered by internally developed sensing technologies - transforming how atmospheric data is captured and used worldwide. Tomorrow.io is seeking a Systems Engineer to aid the development, integration, and verification of an integrated satellite vehicle for our weather observation constellation. In this role, you will translate mission objectives into technical requirements, develop verification and validation plans, manage system risks, and coordinate across multi-disciplinary teams to ensure high reliability and data quality. You will join a collaborative, high-performing environment that values technical excellence, shared accountability, and the pursuit of ambitious, mission-driven engineering goals. What You’ll Do Contribute to the development of integrated satellite payload systems for constellation programs. Support requirements definition, interface coordination, integration planning, test planning and execution, and technical documentation across the payload lifecycle. Collaborate closely with internal and external engineering teams, partners, and scientific stakeholders. Help deliver reliable, mission-ready systems that meet operational objectives. Bridge hands-on engineering discipline with system-level thinking and mission execution. Support architecture definition and technical design across the payload lifecycle from concept through launch and operations. Contribute to system-level trade studies and performance modeling. Establish and maintain requirements, interfaces, and verification documentation. Identify technical risks and support mitigation planning. Collaborate with leadership to track technical performance, support integration test planning, and strengthen engineering quality and systems rigor. What You Bring 4-7+ years of experience developing, integrating, and testing complex engineered systems, specifically satellite payloads or similar hardware. Strong working knowledge of spacecraft subsystems, payload integration, and performance modeling. Proven experience in system-level architecture, requirements management, interface control, and verification planning. Familiarity with model-based systems engineering (MBSE) or similar structured systems approaches. Experience performing system-level trade studies and identifying/mitigating and managing program risks. Familiarity with orbital mechanics and LEO Earth observation constellation design Experience using space mission analysis and simulation tools such as AGI STK, GMAT, Orekit, or equivalent to evaluate mission performance  Ability to collaborate effectively across multi-disciplinary engineering and scientific domains, both internally and externally. Excellent communication skills, with the ability to convey technical topics clearly to diverse audiences. Proven ability to make sound engineering judgments and operate effectively in dynamic, fast-moving development environments. Demonstrated integrity, transparency, and accountability in professional conduct. A system-level mindset that balances technical detail with overall mission execution.
