Systems Engineer

Catalyx Space, Inc.; Ahmedabad District; On-site; INR 1,800,000 - 3,200,000; Full time

Job summary

Catalyx Space is seeking a Systems Engineer to own the definition, integration, and validation of spacecraft and reentry systems across engineering domains. You will work hands-on with propulsion, aerodynamics, thermal, mechanisms, structures, and avionics engineers to ensure the vehicle operates as a coherent system from concept through flight readiness.

You will manage CONOPS, requirements, and V&V plans, maintain system budgets, participate in design reviews, and coordinate with operations

Qualifications

• Bachelor’s/Master’s in Aerospace, Mechanical, or Systems Engineering, or equivalent field.
• 5+ years of experience in spacecraft systems engineering or multi-disciplinary aerospace programs.
• Hands-on experience in requirements flow down, interface control, trade studies, and system-level analyses.
• Proficiency with system budgets (mass, power, ΔV) and regulatory interfaces.

Responsibilities

• Own Requirements definition, flow down, and tracking across all subsystems.
• Develop and maintain system budgets (mass, power, ΔV, volume, stiffness, thermal margins).
• Define system-level interfaces (mechanical, thermal, electrical, fluid).
• Lead integration trades and architecture decisions, ensuring subsystem compatibility.
• Perform trade-off analyses to balance competing requirements across subsystems.
• Perform system-level analyses to validate architecture choices against mission requirements.
• Define and maintain CONOPS, aligning system design with mission objectives and constraints.
• Establish and maintain system-level timelines with awareness of technical risks.
• Participate in design reviews (Preliminary, Critical, Test Readiness).
• Define and own the system verification & validation plan, ensuring test campaigns close requirements.
• Drive configuration management and PLM discipline across teams.
• Conduct FMECA for system reliability.
• Interface with regulatory partners (DGCA/FAA or equivalent).
• Collaborate with operations and GNC/Flight Dynamics teams to ensure vehicle performance.
• Author and maintain system-level documents including CONOPS and test plans.

Job description

We're building AWS for space, providing space experiments and technology demonstrations across LEO, deep space, and lunar orbit.

Our offerings include unmanned labs, testbeds for both dedicated and rideshare missions, and re-entry capsules for payload retrieval.

We simplify access to space with affordable pricing, end-to-end solutions, no minimum mass limits, zero integration fees, and quick deployment (6 months or less).

We serve biopharma, semiconductors, materials science, defence, and more.

Job Description

Catalyx Space is developing next-generation entry systems for space. As a Systems Engineer, you will own the definition, integration, and validation of spacecraft and reentry systems across all engineering domains. You will work hands-on with propulsion, aerodynamics, thermal, mechanisms, structures, and avionics engineers to ensure the vehicle operates as a coherent system. Beyond coordination, you will apply strong engineering problem-solving skills, perform system-level analyses and trade-offs, and establish realistic timelines. You will also be responsible for CONOPS development, requirements management, and operational readiness, ensuring mission success from design through flight.

Responsibilities:

• Own Requirements definition, flow down, and tracking across all subsystems.
• Develop and maintain system budgets (mass, power, ΔV, volume, stiffness, thermal margins).
• Define system-level interfaces (mechanical, thermal, electrical, fluid).
• Lead integration trades and architecture decisions, ensuring subsystem compatibility.
• Perform trade-off analyses to balance competing requirements across subsystems.
• Perform system-level analyses to validate architecture choices against mission requirements.
• Define and maintain CONOPS (Concept of Operations), aligning system design with mission objectives and operational constraints.
• Establish and maintain system-level timelines with awareness of technical risks and bottlenecks.
• Participate directly in design reviews (Preliminary, Critical, and Test Readiness).
• Define and own the system verification & validation (V&V) plan, ensuring test campaigns close requirements.
• Drive configuration management and PLM discipline across teams.
• Conduct and document FMECA (Failure Modes, Effects, and Criticality Analysis) for system reliability.
• Interface with regulatory partners (DGCA/FAA or equivalent) for system compliance.
• Collaborate with operations and GNC/Flight Dynamics teams to ensure vehicle performance meets mission design.
• Author and maintain system-level documents, including CONOPS, requirements docs, V&V plans, and system test plans.

Qualifications:

• Bachelor’s/Master’s in Aerospace, Mechanical, or Systems Engineering, or equivalent field.
• 5+ years of experience in spacecraft systems engineering or multi-disciplinary aerospace programs.
• Prior experience in managing space missions (concept design, integration, testing, and/or operations).
• Strong understanding of propulsion, structures, thermal, aerodynamics, mechanisms, and basic avionics (to manage system interfaces and integration).
• Hands-on experience in requirements flow down, interface control, trade studies, and system-level analyses.
• Ability to define and track mass, power, and ΔV budgets.
• Familiarity with system integration testing (vibration, TVAC, propulsion, aero/thermal).
• Proficiency in tools like STK, MATLAB, Python, and system modelling frameworks.
• Experience conducting or contributing to FMECA analyses.

Preferred Skills:

• Prior experience on spacecraft or reentry systems that have flown.
• Strong problem-solving skills and ability to step into technical challenges outside your core discipline.
• Experience with configuration management tools and PLM systems.
• Familiarity with safety and regulatory compliance in aerospace programs.
• Excellent communication skills, with ability to align diverse teams under one mission timeline.
• Willingness to work extended hours and/or weekends as needed.
