Jobbeschreibung

Your role

Most energy companies are still running on spreadsheets and phone calls. At Cloover we're building the infrastructure that replaces all of that — and we need engineers who want to own real problems, not tickets. We're looking for a Senior Software Engineer to join our Berlin team and take full ownership of core features and infrastructure across our platform, working at the intersection of product, operations, and finance to ship things that reach thousands of installer partners directly.

You'll collaborate closely with cross-functional teams, integrate secure authentication flows, and use AI tools to raise your output without lowering your standards. If you enjoy autonomy, shipping frequently, and tackling challenges across the entire stack — including occasional no-code and low-code systems — you'll feel at home here.

You'll report to our CTO and work within a cross-functional squad. From your first week, your work will be in production.

Your mission

• Own features end-to-end across frontend and backend using modern JavaScript and TypeScript frameworks — from scoping and architecture to shipping and maintaining in production.
• Design, implement, and maintain APIs that are scalable, secure, and documented well enough that the next engineer doesn't need to ask questions.
• Model, optimise, and operate databases — SQL and NoSQL — for performance and reliability at scale, including schema design, indexing, and query optimisation.
• Architect and manage cloud infrastructure on Google Cloud Platform, applying infrastructure-as-code via Terraform to keep environments consistent and auditable.
• Integrate authentication and authorisation flows — OAuth, SSO, session and token management — that are secure, smooth, and don't create friction for end users.
• Use AI coding tools as a natural part of how you work — for productivity, code suggestions, and debugging — while reviewing and owning every line that ships.
• Collaborate daily with Product, Ops, Finance, and Design to translate cross-functional requirements into well-scoped, reliably shipped features.
• Set and uphold high standards for testing, code quality, and maintainability — raise the bar, don't just clear it.

Your profile

We care more about how you think and what you've built than where you've been. Here's what will set you up for success in this role:

• 8–10 years of professional software engineering experience, with strong JavaScript and TypeScript skills across both frontend and backend.
• Strong cloud infrastructure experience, ideally on Google Cloud Platform, with hands‑on Terraform or equivalent IaC practice.
• Database expertise across SQL and NoSQL — schema design, indexing, and query optimisation at production scale.
• Proven API development experience across REST and GraphQL, with a track record of building APIs others can rely on.
• Works independently in a fast-moving environment, takes cross-functional ownership, and moves without waiting to be directed.
• Based in Berlin and energised by being in the room. We're intentionally office-first — decisions get made in real time, prototypes get stress‑tested over lunch, and the founding team is ten metres away. If that's how you thrive, you'll feel at home here.
• Fluent in English.

Nice to have (but not required):

• Knowledge of auth protocols beyond the basics: OAuth, OpenID Connect, SSO, session management.
• Familiarity with no‑code and low‑code platforms — Bubble.io specifically, as parts of our stack use it.

We hire for potential and perspective — credentials are a starting point, not a ceiling.

How we hire

We keep things transparent and respect your time. Most go from first call to offer in under three weeks.

• Intro call (30 min) — We want to understand what you're looking for, not just screen your CV.
• Hiring manager interview (30 min) — We go deep: your experience, your thinking, how you approach problems.
• Case study (1 hour) — You get the brief in advance. We care about your approach — not whether you land on the right answer.
• Offer & signed contract.

Need any adjustments at any stage? Just let us know.

Why us?

• Performance pay. Strong base and a bonus tied to outcomes, recognised when it happens rather than locked behind annual cycles.
• AI-first & unthrottled. Unlimited enterprise-grade AI, no caps, no approval process. Every role, every team. The grunt work disappears so you can focus on what actually requires human judgement.
• Real ownership on a real mission. From day one you're shaping decisions that impact thousands of installers. We're not just building software. We're powering the energy transition across Europe.
• Grow faster than anywhere else. You'll work directly alongside the founding team and world-class investors. If you're building toward your own venture one day, there's no better room to be in.
• WHOOP Peak, covered. After six months with us, we cover your WHOOP Peak membership in full.
• The basics, done well. Prenzlauer Berg office with the latest Apple hardware. Free breakfast and dinner, stocked kitchen, regular team events, 25 days vacation, a fully covered Deutschlandticket, Urban Sports Club (M), and company discounts.
