About the Role

Peak Energy    Job Title: Senior Cell Test & Validation Engineer Location: Broomfield, CO  Department: Cell Engineering Reports To: Cell Applications Engineering Manager Position Type: Full-Time    About Peak Energy     Peak Energy is the first American venture to advance globally proven Sodium-Ion battery systems as the storage standard for the new era of renewable energy on a resilient grid.      Sodium-Ion is cheap, readily available and safe, making it the leading contender in a rapidly evolving market.       Our leadership team is powered by decades of expertise in scaling gigawatt-level innovation at world-class companies such as Tesla, Northvolt, Apple, Powin, Enovix, Zipline, Solid Power, and Fluence. We are backed by strategic investment and product partners such as TDK Ventures and Eclipse Ventures.       We are a team of engineers, operators, entrepreneurs, and partners driven by a shared ambition to set the new performance standard for renewable energy and grid resilience.      If you want to define how a new chemistry is tested, validated, and trusted at commercial scale — and to build the lab, fixtures, and methods that make that possible — we encourage you to apply and help us power a more sustainable future.    About the Role - Senior Cell Test & Validation Engineer Peak Energy is seeking a Senior Cell Test & Validation Engineer to play a key role in the cell-level test and validation program for commercial product cells. This role moves the cell from verification to validation — defining critical-to-quality (CTQ) metrics, designing the test campaigns that prove them out, and building the in-house infrastructure, fixtures, and data systems needed to execute them with rigor. You will lead electrochemical, life, and thermal characterization of cells, own external relationships for third-party safety and abuse testing, and apply a strong statistical foundation to demonstrate that cells meet performance, reliability, and safety expectations at scale.   The successful candidate combines hands-on lab expertise with the engineering discipline to make data-driven, defensible decisions about cells intended for commercial deployment.   What You'll Do (Responsibilities) <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335552541":1,"335559685":540,"335559991":270,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="1" data-aria-level="1">Define and execute electrochemical characterization of commercial product cells, including capacity, DCIR/HPPC, rate capability, OCV/SOC mapping, coulombic and energy efficiency, and incremental capacity / differential voltage (IC/DV) analysis. </li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335552541":1,"335559685":540,"335559991":270,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="2" data-aria-level="1">Own cycle life and calendar life test programs across temperature, SOC, and duty-cycle conditions; design accelerated aging protocols and analyze degradation modes to inform life models and product warranty positions. </li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335552541":1,"335559685":540,"335559991":270,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="3" data-aria-level="1">Design and execute self-discharge characterization (open-circuit, micro-shorts, parasitic loss) at the cell level, including long-duration low-current measurements and storage condition matrices. </li> </ul> <ul> <li data-leveltext="•" data-font="" data-listid="2" data-list-defn-props="{"335552541":1,"335559685":540,"335559991":270,"469769242":[8226],"469777803":"left","469777804":"•","469777815":"hybridMultilevel"}" data-aria-posinset="4" data-aria-level="1">Own third-party test engagements for thermal runaway, heat generation, and abuse testing (e.g., nail penetration, overcharge, external short, propagation, ARC, thermal characterization).
