Senior Structural Engineer

Job Summary

Role Description: At Pixxel, we design, manufacture, test and place satellites in orbits. As a Structural Design and Analysis Engineer, you are responsible for the execution of an end-to-end design cycle of satellite structures including verification validation of the simulation results. Additionally, you are also expected to create BOM, Engineering drawings and interface with manufacturing vendors for successful realization of structure.

Responsibilities

• CAD Modeling of satellite structures, subsystems, avionic package housings, brackets etc.
• Parametric CAD modeling to perform quick design iterations.
• Finite Element Modeling and Analysis of satellite structures - Primary, Secondary and Tertiary.
• Perform Modal, Static, Shock, Acoustic, Sine and Random Vibration analysis using a commercial FEA package (preferably Siemens NX Nastran).
• Perform analytical calculations to estimate design loads involving static and dynamic load cases.
• Generate load profiles for qualification testing of the satellite structure and verify the validity of these loads with the rest of the spacecraft vibration environment.
• Work with the testing team to establish test goals, requirements and pass/fail criteria.
• Perform correlation analysis between FEA and test data to improve FEM modeling methodologies.
• Perform trade-off and case studies on various edge-cases and cross-domain problems that could potentially impact and lead to structural design changes.
• Prepare concept design documentation on demand for pitching design ideas to internal external stakeholders.
• Estimation of Mass Properties at subsystem as well as satellite level.
• Use Optimization techniques for mass / volume reduction to meet design requirements.
• BOM generation and management.
• ECN/ECR management for smooth flow of operations.
• Understanding and generation of Engineering drawings.
• Interfacing with cross-domain teams for information exchange, generate, assume, identify, ask for required inputs to advance the development.

Desirable Skills

• CAD and FEA - preferably using Siemens NX Nastran.
• Understanding of underlying mathematics, limitations and assumptions of the FEA.
• Knowledge of Aerospace materials.
• Knowledge of GDT as per ASME Y14.5, ISO 286, ISO 2768.
• Knowledge of design and testing standards by NASA, ECSS, GSFC etc.
• Design for Manufacturing Assembly (DFMA).
• Failure modes, effects, and criticality analysis (FMECA).
• Analytical and Problem solving skills.
• Technical writing and documentation.
• Ability to work in an agile development environment.

Candidate Acumen

We are looking for a highly motivated and self-initiated individual who is able to work in a flat organizational structure. The ideal candidate will be able to work independently with minimal supervision and can positively add to the Pixxel culture.
