The RoleAs a technical authority on hardware reliability, you will own the development and execution of reliability strategies that enable our spacecraft to meet ambitious vehicle and constellation-level targets for probability of success and availability. You will define reliability requirements, build and apply advanced semi-empirical modeling techniques, and drive testing programs that identify and mitigate risks early in development. This role sits at the intersection of design, test, systems, and manufacturing, where you will integrate reliability models with program risk management and flow down clear, actionable requirements across subsystems. You will lead root cause investigations on critical hardware issues, mentor engineers across the reliability function, and play a key role in shaping K2's reliability strategy as we scale toward high-volume satellite production. The ideal candidate is a technically strong, hands-on engineer who thrives in a fast-paced startup environment and is excited to build the reliability foundation for a new generation of large, capable spacecraft.
Responsibilities- Own the development and maintenance of top-level reliability requirements, models, and allocations across the full spacecraft and constellation portfolio to meet vehicle and constellation-level targets for probability of success and availability
- Define and drive HALT/HASS strategies, accelerated testing plans, and reliability growth programs across spacecraft development and production, including test standardization, lot acceptance derivations, and success-run demonstration analysis to confirm campaigns meet flight-life requirements
- Establish and evolve reliability modelling frameworks, including Weibull and Kaplan-Meier analysis, accelerated failure time (AFT) modeling (e.g., Norris-Landzberg, Arrhenius), Monte Carlo simulations, and Probabilistic Risk Assessment (PRA), reconciling QTP, ATP, HALT, HASS, and flight telemetry data onto a single wear-out model
- Integrate reliability analyses with program risk management and drive actionable insights that influence design, manufacturing, and test decisions
- Flow down reliability requirements to subsystems, including margins, screening levels, derating guidelines, and test requirements, and ensure consistent application across programs
- Lead root cause investigations on critical hardware failures and drive systemic corrective actions that improve product robustness and mission reliability
- Collaborate closely with design, systems, test, and manufacturing teams to embed reliability principles early in the development process and optimize for mass production
- Mentor and develop junior and mid-level engineers on reliability methods, analysis techniques, and best practices, while helping shape the long-term technical direction and growth of the reliability function at K2 Space
- Serve as a technical authority on reliability across multiple spacecraft programs, advising leadership on risk trade-offs and reliability strategy
- Own FRACAS and test-effectiveness tracking to close the loop between failure data, corrective actions, and reliability predictions
- Partner with responsible engineers to implement telemetry and instrumentation for degradation observability on flight and test hardware
- Advance degradation-based and Bayesian reliability methods, including Gamma/Wiener process degradation models and MCMC-based hierarchical pooling, to extend the reliability framework beyond binary pass/fail testing
Qualifications- S. degree in mechanical engineering, aerospace engineering, electrical engineering, materials science, or other related discipline
- 8+ years of experience in reliability engineering, hardware testing, failure analysis, or related fields in the space, automotive, semiconductor, or other high-reliability industries
Nice to have- S. or PhD in mechanical engineering, electrical engineering, chemical engineering, materials science, or other related discipline
- Experience developing and executing life testing methods, including accelerated life testing (ALT) and reliability growth programs
- Experience with accelerated failure time (AFT) modeling, including Norris-Landzberg and Arrhenius acceleration models, for translating ground test severity to flight conditions
- Experience reconciling multiple ground test sources (QTP, ATP, HALT, HASS) and flight telemetry onto a single reliability model, including distinguishing workmanship/infant-mortality failure modes from wear-out mechanisms
- Familiarity with success-run and zero-failure demonstration statistics, and sample-size/DOE methods for reliability test planning
- Exposure to degradation-based reliability modeling (Gamma or Wiener process models, accelerated degradation testing) as a complement to binary pass/fail Weibull analysis
- Experience with thermal, vibration, and TVAC qualification and acceptance testing approaches
- Experience with EEE components (Electrical, Electronic, and Electromechanical), including semiconductor devices and packaging technologies, in high-reliability or space applications
- Experience building reliability prediction models (Weibull, Kaplan-Meier, Monte Carlo, reliability block diagrams) and performing system-level analyses (FTA, PRA)
- Strong foundation in statistical modeling and data analysis, with experience developing custom models for engineering or production data. Experience with Bayesian hierarchical modeling and MCMC tools (e.g., PyMC, Stan, NumPyro) for reliability parameter estimation is a plus
- Proficiency in programming languages (such as Python or C++) for data analysis, statistical modeling, and reliability calculations
- Familiarity with derating practices, Design for Excellence (DFX), and requirements flow-down in complex hardware systems
- Experience with Physics of Failure (PoF) methodologies, including Sherlock or similar modeling tools, and identification of dominant failure mechanisms in electronic hardware and EEE components
- Experience with reliability growth tracking or working toward probability of success / availability targets on vehicles or constellations
- Strong cross-functional communication skills and ability to clearly present technical findings to both engineering and leadership teams
- Experience in a fast-paced startup or new-space environment with high ownership and broad scope
- Familiarity with FRACAS and test-effectiveness tracking processes
Compensation and Benefits:- Base salary range for this role is $185,000 - $220,000 + equity in the company
- Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
- Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks
If you don't meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!
