Working for Form Energy is more than just a job, it’s a chance to be part of something extraordinary. And now - right as we significantly scale up battery manufacturing - might be the most exciting moment in the company’s history to join. We are assembling a team of highly talented and driven individuals across the country. Driven by our core values of humanity, excellence, and creativity, our team is determined to deliver on our mission and transform the energy landscape for the better.

Feeling energized to make a meaningful impact on the world? Then keep reading - you’ve come to the right place.

Role Description

Form Energy is hiring a Test Engineer II to join our Test Engineering team. In this position, you will work closely with mechanical and structural design teams to develop custom vibration fixtures and testing campaigns for our iron-air battery systems. You will collaborate with internal teams and external labs to execute transportation shock/vibration and seismic qualification testing, taking responsibility for data acquisition, processing, and reporting findings back to design teams. This is a highly impactful, hands‑on opportunity to join a growing team and establish the testing frameworks that ensure our revolutionary grid‑scale technology survives real‑world environments.

Relocation assistance is available.

What you’ll do:

• Test Strategy & Execution: Develop, execute, and own comprehensive qualification test strategies, running shaker table random vibration, shock, and seismic testing campaigns across battery modules, enclosures, and structural assemblies.
• Fixture Design & Modal Analysis: Design and develop specialized test fixtures to mount and excite test articles, and perform modal analysis to validate fixture performance before physical testing.
• Cross-Functional Collaboration: Partner directly with structural, packaging, and mechanical design engineers to translate transportation, seismic, and field requirements into testable, repeatable specifications.
• Instrumentation & Data Acquisition: Instrument test articles with accelerometers and strain gauges, configure data acquisition systems, and apply relevant test standards (such as MIL-STD-810) to create new component-level test profiles.
• Data Processing & Reporting: Analyze, post‑process, and reduce vibration data to identify trends or anomalies, and generate detailed technical reports outlining pass/fail criteria and design recommendations.
• Lab Support & External Travel: Drive continuous improvement within the lab environment, support root‑cause investigations when hardware fails, and travel up to 20% to external test facilities to execute vibration testing.

What you’ll bring:

• Education & Experience: Bachelor’s degree in Mechanical Engineering, Structural Engineering, or a related field, combined with 3+ years of industry experience in shock, vibration, or structural hardware testing.
• Testing Hardware Literacy: Hands‑on proficiency with electrodynamic or hydraulic shaker systems, shock testers, data acquisition hardware, and a solid understanding of structural dynamics (natural frequency, resonance, and damping).
• Software & Analysis Skills: Proficiency in Python or MATLAB for equipment control and data processing, with the ability to convert raw validation data into meaningful engineering conclusions.
• Test Protocol Expertise: Proven ability to interpret and build upon existing standards (like MIL-STD-810) to create new validation protocols and lead root‑cause failure investigations.
• Hands‑on Aptitude: Strong mechanical intuition and comfort working in an R&D lab environment setting up new test capabilities, fabricating fixtures, and using mechanical hand tools.
• Collaborative Communication: Exceptional cross‑functional communication skills, with a track record of gathering multidisciplinary stakeholder input and delivering clear technical findings to a wide audience.
