Harmattan AI

ABOUT US Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. ABOUT THE ROLE We are looking for a UAV Battery Engineer to join our Hardware (Elec Team). This role is critical to owning the energy storage systems that power our UAV platforms. Our drones demand high energy density, reliability, and uncompromising safety under dynamic loads — and we need a dedicated expert to architect, test, and deliver battery systems from cell selection through to production-ready packs. You will take end-to-end ownership of the UAV battery architecture, working hands-on with cells, BMS hardware, and thermal systems every day. This is a high-autonomy role where your decisions on cell chemistry, supplier selection, and safety protocols will directly shape the performance and reliability of our platforms. RESPONSIBILITIES Battery Architecture & Cell Selection: Evaluate and qualify battery cell suppliers based on energy density, cycle life, cost, and safety performance. Define pack configuration and cell architecture for UAV platforms. Battery Safety & Thermal Management: Lead the design of battery safety protocols, including thermal runaway mitigation and propagation resistance strategies. Conduct hazard analyses (DFMEA) and ensure compliance with standards such as UN38.3 and UL. BMS Design & Integration: Own the Battery Management System architecture and algorithms, including State of Charge (SoC) and State of Health (SoH) estimation, cell balancing, and protection logic for highly dynamic load environments. Testing & Validation: Perform hands-on testing of cells using cyclers and thermal chambers. Develop validation plans covering abuse scenarios such as overcharge, short circuit, and mechanical drop conditions. Analyse BMS log data and simulate thermal behaviour. Supplier Management: Manage relationships with cell suppliers, covering technical specifications, quality control, and roadmaps. Build a reliable and scalable supplier pipeline. Cross-Team Collaboration: Work closely with Mechanical Design on battery packaging constraints, Firmware on BMS parameters and algorithms, and external manufacturing partners. CANDIDATE REQUIREMENTS Educational Background: Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Materials Science, Chemical Engineering, or a closely related field. Technical Expertise: Proven track record of taking battery systems from concept to production in high-performance robotics, aerospace, or UAV applications. Hands-on experience with cell characterisation, BMS architecture, and thermal management. Familiarity with safety compliance standards (e.g., UN38.3, UL). Core Competencies: Cell selection and testing, supplier management and qualification, battery safety (thermal runaway mitigation), BMS architecture, pack packaging and integration, and regulatory compliance. Ideal Background: Experience at drone manufacturers (e.g., DJI, Skydio, Anduril), EV companies (e.g., Rivian, Tesla), or advanced robotics and electrification organizations. Attributes: Analytical, safety-conscious, data-driven, and highly structured. Strong communication skills, particularly for supplier negotiation and cross-functional collaboration. Commitment: 100% dedication to Harmattan AI's mission, vision, and ambitious growth plans, ready to go the extra mile to ensure operational excellence. We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.

With 3,000+ experts across North America, we partner with leading companies in aerospace, medical devices, robotics, automotive, commercial vehicles, EVs, rail, and more. As part of the global ALTEN Group—57,000+ engineers in 30 countries—we deliver across the entire product development cycle, from consulting to full project outsourcing. When you join ALTEN Technology USA, you’ll collaborate on some of the world’s toughest engineering challenges, supported by mentorship, career growth opportunities, and comprehensive benefits. We take pride in fostering a culture where employees feel valued, supported, and inspired to grow.   Powertrain Reverse Engineer   Project Summary We operate an autonomous-driving fleet built on the Toyota Highlander hybrid platform. The added compute load draws significantly more power than the stock hybrid system was designed to supply, causing the high-voltage battery to deplete and trigger faults that take vehicles out of service. The vehicle CAN bus has already been decoded for driving functions, but the hybrid control system — charging logic, battery state of charge, and thermal management — remains undecoded. We are looking for someone to reverse-engineer these hybrid/powertrain signals and deliver an updated DBC file so we can monitor and ultimately resolve the battery-depletion issue.   Key Responsibilities & Deliverables * Capture and analyze CAN traffic on-vehicle (with driver/technician support) * Reverse-engineer undecoded hybrid battery, charging, thermal, and powertrain diagnostic signals * Produce a validated, updated DBC file and submit it as a pull request to our repo * Re-run captured data against the new DBC to validate signal accuracy * Document decoded signals and methodology   Must-Have Skills * Hands-on automotive CAN bus reverse engineering experience * DBC file authoring/editing * Proficiency with Vector CANalyzer/CANoe (or equivalent) for trace capture and analysis * Working knowledge of hybrid/EV powertrain and battery management systems (BMS) * Comfortable reading raw CAN traces and isolating/decoding unknown signals * Version control / Git pull-request workflow   Preferred / Nice-to-Have * Direct experience with Toyota hybrid systems (THS) and Toyota diagnostics (Techstream/TIS) * Python (or similar) for CAN data analysis * Familiarity with AI-assisted coding tools (e.g., Cursor/Claude) — we use these to accelerate decoding * Prior work decoding OEM "black box" control modules   Tools & Resources Provided TIS laptop, CANalyzer, Cursor, Claude, GitHub access, scheduled vehicle time, plus VO driver, technician (TIS access), and supporting/firmware engineers. Salary Range: $120,000-$135,000/K The actual salary offered is dependent on various factors including, but not limited to, location, the candidate’s combination of job-related knowledge, qualifications, skills, education, training, and experience  All qualified applicants will receive consideration for employment and will not be discriminated against on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, disability, protected veteran status, age, genetic information, or pregnancy.
