Director of Electrical Engineering managing large engineering teams and complex technical projects at Sierra Space. Overseeing electrical programs and ensuring strategic alignment with organizational goals.
About the role
- Control/Electrical Engineer specializing in Battery Managing Systems for Ford’s Electric Vehicles team. Engaging in hardware design, development, and validation for high voltage battery systems.
Responsibilities
- Design and iterate BMS hardware subsystems (cell sensing, passive/active balancing, pack power distribution, pre-charge/isolation circuits, contactor control, isolation monitoring, current sensing and protection).
- Author and release high-quality engineering artifacts: schematics, PCB layouts, BOMs, assembly drawings, and detailed change records that meet safety, manufacturability, and cost targets.
- Perform Worst Case Circuit Analysis (WCCA) for circuits: define assumptions, compile component tolerance stacks, run worst case and Monte Carlo simulations (SPICE/statistical tools), analyze environmental and aging effects, and document margins and mitigations in formal WCCA reports.
- Bring up and validate hardware in the lab: design test fixtures, develop and execute functional and environmental test plans (thermal, vibration, EMC/EMI pre compliance), collect and analyze data, and close design gaps through iterative updates.
- Work closely with software and system integration teams to define and verify ADC timing, sampling strategies, communication, diagnostics, and HW–SW interfaces; support hardware/software co-debugging during bring-up.
- Apply ISO 26262 functional safety processes in day-to-day work: contribute to HARA/ASIL discussions, derive and trace hardware safety requirements, support DFMEA/FMEDA activities, and produce hardware verification evidence needed for safety cases.
- Implement and verify diagnostic coverage and fault handling features (watchdogs, redundancy, self-test, isolation fault detection) and ensure designs meet target ASIL requirements where applicable.
- Drive root cause analysis for failures in lab and field, define corrective actions, and implement design, test, and supplier changes to prevent recurrence.
- Optimize designs for cost, manufacturability, testability, and supply chain robustness; evaluate and qualify components and collaborate with suppliers on components, prototypes, and design transfers.
- Create and maintain production test plans and automated test fixtures; work with manufacturing and test engineering to ramp products, stabilize yields, and resolve quality escapes.
- Document technical decisions, tradeoffs, and test evidence; present design status and risk mitigation to cross functional stakeholders and participate in design reviews and gate reviews.
- Mentor junior engineers and technicians through hands on guidance during bring up, test, and documentation activities; contribute to continuous improvement of hardware design and validation processes.
Requirements
- Bachelor’s Degree in Electrical Engineering or Electronics Engineering or equivalent combination of relevant education and experience.
- 3+ years’ experience in high voltage battery systems.
- 3+ years’ relevant hardware design or validation experience.
- Familiarity with ISO 26262 functional safety concepts.
Benefits
- Immediate medical, dental, vision and prescription drug coverage
- Flexible family care days, paid parental leave, new parent ramp-up programs, subsidized back-up child care and more
- Family building benefits including adoption and surrogacy expense reimbursement, fertility treatments, and more
- Vehicle discount program for employees and family members and management leases
- Tuition assistance
- Established and active employee resource groups
- Paid time off for individual and team community service
- A generous schedule of paid holidays, including the week between Christmas and New Year’s Day
- Paid time off and the option to purchase additional vacation time.
