Certification Engineer
Rebaba AB · Lidingö · Tills vidare · Deadline 2026-10-25
Rebaba AB is recruiting a **Certification Engineer** to build and lead the end-to-end certification process for its circular battery energy storage systems (BESS) built from second-life EV batteries. Based between engineering, quality, and delivery, the role involves interpreting European directives and international standards—such as LVD, EMC, the EU Battery Regulation, IEC 62619, and UN 38.3—and translating them into traceable technical requirements. Responsibilities include defining testing protocols, leading hazard and risk analyses, managing external relationships with test labs and notified bodies, and maintaining all technical compliance files and declarations of conformity. Candidates must have hands-on experience with **power electronics and electrical systems** in domains such as UPS systems, PV inverters, LV switchgear, EV charging, motor drives, EV battery packs, or stationary battery backups. Essential capabilities include a strong grasp of core electrical concepts like insulation coordination, power conversion, and short-circuit protection, alongside proficiency in reading electrical schematics, structured requirements management, and **professional English** proficiency. Desirable assets include prior experience with product certification, CE marking, relevant IEC standards (such as IEC 62933 or IEC 62477-1), battery chemistry or second-life applications, direct contact with test laboratories, and Swedish language skills.
Rebaba is building circular battery systems from second-life EV batteries. Our products power buildings, industries, and charging infrastructure while reducing costs and emissions. We design and assemble our systems in Sweden and combine hardware, embedded software, and cloud control into one integrated platform.
We are now hiring a Certification Engineer to build and own our certification process from the ground up, making sure everything we design, build, and ship meets the standards, directives, and safety requirements. You will shape how Rebaba certifies BESS systems today and become one of the few real experts in the world in certifying second-life BESS. If you want to go deep on real electrical systems, own a process end to end, and become a genuine expert in a field that barely exists yet, we would love to hear from you.
As Certification Engineer at Rebaba you will own the full certification process for our BESS products, from reading and interpreting the applicable directives and standards, to defining what needs to be tested and how, to producing the technical documentation that proves it. This is a hands-on role that sits between engineering, quality, and delivery. You will work closely with our engineering team and external certification partners, and over time become the internal and external authority on what it takes to certify second-life battery systems for European markets.
Responsibilities
- Build, own, and continuously improve Rebaba's certification process for BESS products, covering LVD, EMC, and the EU Battery Regulation
- Interpret and apply the standards, directives, and regulations governing battery systems, electrical safety, EMC, and enclosures (e.g. IEC 62619, IEC 62933, UN 38.3, CE marking, the Low Voltage and EMC Directives, RoHS), and determine which requirements are applicable to our specific product design
- Translate standards and customer, grid, and safety requirements into clear, traceable technical requirements for the engineering teams, and maintain requirements traceability across product development
- Define what tests need to be run, how, and against which acceptance criteria, based on the relevant standards
- Plan and manage compliance and certification activities as projects - scope, timeline, testing, documentation, and sign-off
- Coordinate and align certification processes with notified bodies, test labs, and external partners; select and manage external test labs
- Own technical compliance documentation, including declarations of conformity, technical files, risk assessments, and test reports, ensuring every compliance claim is traceable to a primary source
- Lead product safety, hazard, and risk analyses for our battery systems
- Track open regulatory and standard-interpretation questions, escalate where needed, and drive them to closure
- Work closely with electronics, mechanical, software, and quality teams to build compliance into the design from the start
- Keep Rebaba ahead of evolving standards and regulatory requirements in energy storage, and feed changes back into the product
- Lay the path for how certification scales as Rebaba expands into new products and markets
Requirements
- Experience with power electronics and electrical systems in one or more of: UPS systems, PV inverters, LV switchgear, EV charging infrastructure, motor drives/VFDs, EV battery packs, or stationary battery/backup power systems
- Solid understanding of core electrical concepts relevant to BESS: insulation coordination, DC/DC or DC/AC power conversion, contactor/switching logic, short-circuit protection
- Comfortable reading and working directly with electrical schematics and system architecture, not just specifications
- Well-versed and structured in requirements analysis and requirements management
- Comfortable working across electronics, mechanical, and software teams and translating between them
- You are exceptionally rigorous and precise, read regulations and standards carefully and literally
- You have the patience to trace every claim back to its source, and the discipline to keep detailed, structured records over long-running projects
- Professional English; Swedish is a plus
- You thrive in an entrepreneurial environment with fast decision cycles and high autonomy
- You are excited about clean energy and want to build something you believe in
Meriting
- Prior experience with product certification, CE marking, or regulatory compliance
- Experience with IEC 62933, IEC 62477-1, IEC 61439-1, IEC 62619, or IEC 60664-1
- Background in battery chemistry, EV batteries, or second-life applications
- Prior direct contact with notified bodies or testing laboratories
- Experience with gap analysis or risk tracking in technical/regulatory projects
Benefits
- Own certification end to end, in a field where the playbook is still being written
- Become one of the few real experts in certifying second-life BESS, in Europe or anywhere
- Close collaboration with a small, hands-on engineering team
- A mission-driven company focused on sustainable energy solutions
- A clear path to grow as Rebaba scales - in seniority, responsibility, and scope
