Jobs at Proper Voltage

Own the sourcing and procurement strategy for custom mechanical components, including supplier development, RFQs, negotiations, should-cost modeling, risk mitigation, and production readiness. Build and qualify suppliers across North America and Asia, support NPI and production scaling, manage long-lead items, and establish supplier performance processes. The role is an individual contributor initially, with potential to build a sourcing team.

Own real-time firmware for bidirectional DC/DC converters in safety-critical battery systems. Design and implement discrete-time control loops, protection functions, deterministic ISR and scheduler architectures, operating-mode arbitration, and portable control libraries. Bring up converter hardware, validate loop stability and transient performance, correlate models with measurements, and maintain simulation, hardware-in-the-loop, specifications, and certification evidence. Review embedded code and contribute to hardware design reviews involving sensing, ADCs, PWM, and protection paths.

Leads real-time firmware for bidirectional DC/DC converters, implementing control loops, compensators, protection logic, mode arbitration, deterministic ISR scheduling, and hardware abstraction. Brings up converter hardware, verifies firmware against control models, measures timing and performance, supports certification evidence, and leads code reviews and power conversion firmware architecture.

Lead control design for bidirectional DC/DC power converters in safety-critical battery energy storage systems. Develop plant models, compensators, digital control specifications, operating modes, protections, and closed-loop simulations. Validate production C code against models, correlate simulations with hardware measurements, characterize stability and transient response, support certification evidence, and guide firmware and hardware teams. The role also provides technical leadership for converter control practices and reviews.

Develop and validate C firmware for battery management systems on STM32 Arm Cortex-M platforms. Implement peripheral drivers, battery monitoring, protection, cell balancing, CAN/CANopen communications, tests, and board bring-up. Debug hardware using laboratory equipment, support safety certification requirements, document designs and procedures, and participate in code reviews. This onsite role focuses on production embedded firmware for safety-critical energy storage products.

Proper Voltage accepts general interest applications for future Business and Operations opportunities. The company develops intelligent battery systems using advanced chemistries, including sodium-ion, lithium-titanate, and lithium-silicon, for robotics, data centers, defense, drones, and autonomous vehicles. Applications are reviewed on a rolling basis, with candidates contacted when a suitable opportunity becomes available.

Own company revenue across direct, OEM, and distributor channels; close complex technical hardware deals; manage strategic negotiations, pricing, forecasting, CRM discipline, and commercial agreements. Lead and develop the sales organization, design hiring and compensation plans, build channel and marketing programs, translate customer requirements for engineering, and ensure commitments align with supply chain, production capacity, margins, and delivery capabilities.

Supports product and program initiatives by managing timelines, deliverables, risks, dependencies, stakeholder communications, requirements, research, launches, and cross-functional coordination. The role suits an early-career engineer who can navigate ambiguity, learn unfamiliar domains, and bring structure to multiple workstreams across design, engineering, marketing, and operations.

Own battery module and pack mechanical design from concept through production. Lead thermal and structural simulation, select interface materials, run thermal and mechanical validation testing, analyze root causes, and drive corrective actions. Manage CAD revisions, BOMs, engineering documentation, design reviews, tolerance analysis, and DFM decisions. Collaborate with electrical, controls, and manufacturing teams while mentoring junior mechanical engineers and making independent design trade-offs.

Build and own the company’s S&OP, demand forecasting, capacity modeling, and scenario-planning processes. Reconcile demand with contract manufacturer throughput, equipment constraints, and cell supply. Initially manage materials execution, including purchase orders, supplier expediting, shortage recovery, and build readiness. Lead cross-functional alignment among sales, engineering, procurement, suppliers, and leadership, eventually hiring and transitioning execution responsibilities to a dedicated team member.
