Sparkmate is a tribe of fearless makers, solving the world’s most pressing problems with hard tech and industrial solutions. Originally an engineering services company, we have pivoted to focus on developing electric steel production technology. Our goal is to transform the $1.5T global steel industry through the complete electrification of primary ironmaking, eliminating reliance on fossil fuels and driving industrial decarbonization at scale.

We are looking for makers, builders, and innovators who are ready to turn this vision into reality.

About the Role

We're looking for an R&D Engineer with a passion for electrochemistry and electrometallurgy — whether you're experienced or just getting started.

In this role, you will be involved in experimental research, materials development, and process innovation.

What you'll do:

• Run and improve experimental electrochemical setups
• Design and conduct lab-scale tests
• Analyze materials, track performance, and troubleshoot experiments
• Collaborate closely with the team to iterate on process design and scale-up

What We're Looking For

• You’re excited about industrial decarbonization and making a physical product
• Hands-on mindset — you’ve built or tested something real (lab, uni project, personal builds)
• Basic chemistry lab skills — e.g., safety practices, accurate measurement, solution prep, titration, and chemical handling/storage
• Comfortable in a lab setting and open to learning fast
• Knowledge in electrochemistry principles (e.g., charge transfer, current-voltage relationships)

Not required, but a plus:

• Hands-on experience with experimental electrochemical cell setups
• Background in Materials / metallurgical is a bonus
• Proficiency in materials characterization techniques
• Strong data analysis skills (Python, MATLAB)
• Familiarity with thermodynamic modeling & calculations

Educational Background:

• Electrochemistry, Chemical Engineering, Materials Science, Metallurgical Engineering, or a related field

Why Join Us?

• Be part of a young, dynamic, and international team of makers
• Work in a hands-on environment where your ideas and contributions truly matter
• Flat hierarchy with trust, ownership, and continuous learning
• Daily team lunches
• Rocking Fridays (Team Building) every 5th week
• Healthcare coverage
• 25+ holidays per year
• Salary 30,000-40,000 hkd per month pending on experience

Start Date & Location

Jun 1, 2025 or sooner

Location: The job is onsite in our Hong Kong office in Kwai Chung.

Application Process

To be considered for this opportunity, please send the following documents to [email protected]:

• A portfolio – A document showcasing the projects you have worked on (personal, school, or work-related). The format is flexible (PDF, Word, website, YouTube, etc.) but we recommend pictures.
• A cover letter detailing your motivation to join Sparkmate and why you would be a good fit.
• A CV (optional).

If you are invited for an interview, we will share a personality test later.

⚠️ Important: Applications without a portfolio will automatically be rejected. If your work is covered by an NDA, we expect you to be creative 😉.
