Role: Sr. Mission Design Engineer
Employment Type: Full Time
Educational Qualification: Bachelors / M.Tech / MS / Ph.D in Aerospace Engineering, Physics, Controls or equivalent
Work Experience: 4+ years of industry experience
Role Description
The Senior Mission Design Engineer is a technical leader responsible for owning end-to-end mission design across multiple programs. This role requires deep expertise in astrodynamics, system-level trade studies, and mission architecture, combined with the ability to translate commercial and program requirements into robust, executable mission designs. You will be responsible for the entire lifecycle of mission development, from initial concept and feasibility studies to detailed mission design and operational support
You will lead complex trade-offs, define mission-level requirements and CONOPS, develop integrated mission analysis frameworks, and act as a key technical interface between mission planning, subsystem teams, and program leadership.
Responsibilities & Duties - Mission & Orbit Architecture
- Independently design, analyze, and optimize satellite or constellation missions across all lifecycle phases: launch, commissioning, nominal operations, station-keeping, and end-of-life disposal.
- Perform advanced orbit and constellation design, maneuver planning, coverage, revisit, and performance analyses.
- Provide multiple mission architecture options with quantified trade-offs across performance, cost, operational complexity, and risk.
- Anticipate mission constraints and proactively propose mitigation strategies.
- System-Level Analysis & Trade Studies
- Lead system-level trade studies across multiple mission concepts, architectures, and operational strategies.
- Balance mission objectives against spacecraft constraints, operational feasibility, and program timelines.
- Clearly communicate trade study outcomes and recommendations to technical leadership and program stakeholders.
- Cross-Functional Systems Integration
- Act as the mission design focal point across subsystem teams (Systems, AOCS/GNC, Propulsion, Power, Communications, Payload, Mission Operations, Thermal).
- Independently develop, own, and maintain Concept of Operations (CONOPS) and Mission Design & Analysis documentation for programs.
- Work closely with program and commercial teams to interpret requirements and assess their technical and operational impact.
- Anticipate cross-system interactions, identify integration risks early, and define mitigation approaches.
- Mission Design Tools, Automation & Simulation
- Develop and maintain integrated mission simulation environments combining multiple tools, models, and data sources.
- Implement advanced automation, batch analyses, and dashboards to support rapid trade studies and decision-making.
- Write high-quality, reusable Python/Java code and contribute shared libraries, templates, or workflows for team-wide use.
- Technical Leadership and Mentorship
- Provide technical guidance and design reviews for junior and mid-level mission design engineers.
- Establish best practices for mission analysis, documentation, and reproducibility.
- Support proposal development, early-phase mission studies, and external technical discussions as a subject-matter expert.
Required Skills
- Strong expertise in orbital mechanics, astrodynamics, classical dynamics, and the LEO space environment.
- Extensive experience with mission design and analysis tools (e.g., STK, Orekit, GMAT, FreeFlyer, or equivalent).
- Advanced programming skills in Python (preferred) or Java, with experience building reusable analysis pipelines.
- Proven ability to lead complex analyses and make system-level design decisions.
- Strong technical documentation and communication skills, with experience presenting to senior stakeholders.
Desired Skills
- Experience across the full lifecycle of LEO spacecraft missions.
- Exposure to constellation design and operational mission planning.
- Familiarity with version control systems (Git) and collaborative development workflows.
- Experience supporting proposals, early mission studies, or customer-facing technical discussions.
- Prior operational mission support or flight dynamics experience.

About Pixxel
Pixxel is a space data company, building a constellation of hyperspectral earth imaging satellites and the analytical tools to mine insights from that data. Pixxel’s constellation is designed to provide global coverage every 24 hours and help detect, monitor, and predict global phenomena across agriculture, mining, environment and energy use cases.
Pixxel is on a mission to build a health monitor for the planet through a constellation of cutting-edge hyperspectral small satellites. This unique hyperspectral capability will be the key to unearth underlying, unseen problems that are invisible to satellites in orbit today.
Pixxel has collaborated with prominent organizations such as the Indian Space Research Organization, NASA JPL, and SpaceX among other leaders in the space industry. The organization is backed by Lightspeed, Radical Ventures, Relativity's Jordan Noone, Seraphim Capital, Ryan Johnson, Blume Ventures, Sparta LLC and Accenture among others.
Recently, Pixxel successfully raised $36 Million in its Series B funding round, with participation from new investors like Google, alongside existing investors, bringing the company's total venture funding to $71 Million.
