THE COMPANY

Max Joule https://maxjouletech.com/ develops and manufactures battery cells and systems for a range of industries including space, medical, mining, and defence. We closed a EUR 1.1 million seed round, we're cash positive, and we have our first commercially ready battery cell in production at our manufacturing plant in Tallinn.

We're an early-stage company run by two hands-on founders, with a growing engineering team in Estonia. Our ambition is to become a leading specialist battery manufacturer in Europe.

THE ROLE

We're opening our first presence in Ukraine, and this is the person who will build it. You'll be our technical face on the ground - testing our batteries with local manufacturers and units, troubleshooting when things don't work, and building the customer relationships that grow our presence in the market.

This is a genuinely dual role. Roughly half of it is hands-on technical work: receiving equipment, running tests, modifying and repairing hardware, feeding real-world findings back to our engineering team in Tallinn. The other half is commercial and operational: opening doors with new customers, attending industry events, and handling the practical side of getting our Ukrainian operation off the ground - including setting up the office itself.

You'll report directly to one of the founders and work closely with the Estonian engineering and manufacturing team.

WHAT YOU'LL DO

• Receive our materials and equipment in Ukraine and run testing with local manufacturers and units
• Troubleshoot technical issues on-site, including hands-on modification, soldering, and assembly
• Answer customer questions on product functionality, performance, and integration
• Support customers through deployment, testing, and operational use
• Bring customer feedback, issues, and feature requests back to our engineering team
• Proactively reach out to and build relationships with new customers and partners
• Represent us at meetings, trade fairs, and industry events
• Handle physical logistics, including moving stock and delivering parts to customer sites
• Set up and run the day-to-day operations of our Ukrainian unit, including finding our office and supporting company registration
• Travel to customer and partner locations across Ukraine

YOUR FIRST FEW MONTHS

• Get our office and operational presence in Ukraine up and running
• Support the company registration process
• Pick up conversations already underway with units and manufacturers, and move them into testing and sales
• Work with the Estonian team to establish a smooth process for shipping battery cells into Ukraine

WHAT WE'RE LOOKING FOR

Essential

• Technical education at technician level or above - practical capability matters more to us than formal qualifications
• Hands-on experience with electronics or battery systems, at cell or pack level
• Ability to read CAD drawings and electrical schematics
• Practical troubleshooting, soldering, and equipment modification skills
• Comfortable working independently, without someone looking over your shoulder
• Ukrainian at native or fluent level, and English at working proficiency

Nice to have

• Experience working with army units, or having served
• Experience building battery packs or energy storage systems
• Background in sales, business development, or account management
• Higher education in electrochemistry, electronics, or electrical systems
• Ability to produce CAD drawings and electrical schematics
• Valid driving licence
• An existing network in the Ukrainian technology or manufacturing ecosystem

WHO THRIVES HERE

Our culture is strongly engineering-driven. People are valued on what they deliver, not on their title. Everyone is expected to be flexible and do what the task requires, including practical work outside their formal remit - the founders do it too.

We're looking for someone who is proactive and self-managing, comfortable with ambiguity, curious, and happy to wear several hats at once. You'll also be the face of the company in front of customers, so being credible and professional in that setting matters.

If you have a better idea about how to do something, we want to hear it. We'd rather try it and find out than default to how things have always been done.

WHAT WE OFFER

• Flexible working - work where you want, as long as the job gets done
• Company van for deliveries and site visits
• Laptop and phone
• Life insurance
• Competitive salary
• Sales-linked performance incentive

GROWTH

This role is the beginning of something much bigger. We expect our Ukrainian office to grow substantially, and local manufacturing is a real possibility as we scale. Depending on where your strengths lie, you could grow into a country manager role here, move deeper into engineering, or transfer into a position in Estonia or wherever we open next.

Backend / Product Engineer (Elixir-driven) — Remote (EU) | US Startup

Location: Europe (3–6h overlap with US hours)

Type: Full-time, remote (B2B contract)

Stack: Elixir, Phoenix, PostgreSQL, AWS, Oban, GraphQL/REST

About Us

We’re a fast-moving U.S. startup building real products, not slide decks. We operate like an elite, small engineering team: high ownership, high expectations, zero bureaucracy, and extremely high output.

We’re hiring a Backend/Product Engineer who can think, build, and deliver — someone who doesn’t need perfect specs and can create value even when no one assigns tasks.

You will build core systems, integrations, APIs, and internal tools that directly impact customers. This is a role for someone who wants responsibility, challenge, and growth — not a “soft-cushion corporate dev seat.”

What You’ll Do

You will operate as a true Product Engineer, not a ticket monkey:

• Design and implement backend systems, APIs, and services
• Own features end-to-end: idea → architecture → implementation → deploy
• Work closely with founders and product to define problems and solutions
• Improve architecture, observability, and reliability without waiting to be told
• Identify gaps and build tools that save us time or money
• Take responsibility for outcomes, not excuses

We move fast. We expect ownership. We expect results.

Your Background

We care more about your ability to build great systems than whether you’ve used the exact stack before.

Must-Have

• Strong backend engineering experience (any modern language)
• Solid understanding of databases, transactions, APIs, distributed systems
• Ability to work independently and ship high-quality features
• Comfortable with early-stage chaos and ambiguity
• Strong communication skills (clear, concise, proactive)
• A mindset that says: “If it’s broken, I fix it.”
• Comfortable overlapping with US hours

Nice-to-Have (or willingness to learn)

• Elixir, Phoenix, Ecto, Oban
• OTP fundamentals (GenServers, Supervisors)
• Event-driven thinking
• Fintech/payments/ledger experience
• AWS experience
• Typescript
• React native
• Tailwind/css
   

Mindset We Expect

Let’s be upfront:

This is not a role for someone who wants:

• low pressure
• slow pace
• heavy process
• “assignments” waiting for them every morning
• perfect specs
• or a 9-to-5 corporate comfort zone

This is a role for someone who:

• thrives in high-ownership environments
• enjoys solving problems without hand-holding
• does not cop out when things get tough
• treats the product like their own
• wants to build something meaningful and challenging
• understands that early-stage startups require real commitment
• wants to grow into a senior/product/lead role fast

We are building for real customers.

This requires focus, discipline, and hustle.

If you’re not comfortable with that — this isn’t for you.

If you are — you will absolutely love working with us.

Why Join Us

• Work directly with founders (no layers of management)
• Build real product that ships weekly
• Ownership of architecture and systems
• Autonomy + trust (but also expectations)
• Modern, enjoyable stack
• Competitive USD-based compensation
• A place where ambitious engineers grow fast
• Your work actually matters

🔹 Solid understanding of async programming, REST APIs, microservices, and testing — enough to read, review, and validate implementations, not just write them yourself.
🔹Hands-on experience with AI coding tools (Claude Code, Cursor, Codex, GitHub Copilot, or similar) and building AI-native workflows, with the ability to review, challenge, and improve AI-generated output rather than relying on it blindly.
🔹Strong hands-on experience with PostgreSQL and relational databases — proven experience configuring, managing, and optimizing large-scale databases, working with high volumes of data, and ensuring performance, scalability, and reliability in production environments.
🔹 Strong product mindset — able to balance technical and business priorities, thrive in ambiguous, fast-moving environments, and take full ownership of outcomes.
🔹 Exceptional communication skills and high proficiency in English (Upper-Intermediate or higher) — you’ll partner directly
with Product and own the technical execution.

Will be plus:

🔹Understanding of CI/CD pipelines and IaC tools (Terraform, Helm) — enough to decide what the system needs and evaluate what an agent produces.
🔹Familiarity with Celery orchestration, event-driven architectures, or streaming frameworks (RabbitMQ).
🔹Exposure to modern frontend, QA automation, or full-stack environments.
🔹Experience working in product companies or startups.

What you will do:

🔹Own features end-to-end, from initial requirements to production and monitoring.
🔹Partner with Product to turn requirements into clear execution plans — Product owns the what, you own the how.
🔹Orchestrate AI agents across development, QA, and automation.
🔹Review, validate, and improve AI-generated code and solutions.
🔹Make architectural decisions, define data models, and optimize system performance.
🔹Ensure high quality throughout the entire delivery lifecycle.
🔹Own a feature area while contributing across other areas when needed.
🔹Collaborate directly with engineering and product teams to continuously improve delivery
