Senior Platform Engineer - Climate-Tech SaaS- Germany
We’re FIDgate, a Berlin-based climate-tech startup building a decision platform that helps renewable energy teams design and finance better projects — faster and with more confidence.
FIDgate
We are currently transitioning from pilot execution toward scalable productization through a major German EXIST-backed startup program.
IMPORTANT NOTE: ? EXIST eligibility requirement: Candidates must have obtained their most recent university degree (BSc or MSc) within the last 5 years and a valid work permit. . This is a formal requirement of the EXIST scholarship program — not a reflection of the seniority or experience level we're looking for.
The Role
We are looking for a Senior Platform Engineer to own the platform layer of the company:
- APIs and backend systems
- Simulation orchestration infrastructure
- Authentication, user management, and permissions
- Cloud-native infrastructure and deployment workflows
- Web application backend systems
- AI-assisted workflow infrastructure
- Technical foundations for SaaS scaling
This is a senior, high-autonomy role on the company's critical path. You will work directly with the founder and modelling team to transform advanced engineering workflows into a reliable, scalable SaaS platform used by renewable energy developers, investors, and infrastructure stakeholders.
You are joining a platform with working foundations — optimization engine, authentication, cloud infrastructure — and taking it from MVP to production-grade. This is not a greenfield role, but it is a high-ownership one.
The platform is built on a modern Python and TypeScript stack, running on cloud infrastructure across AWS and GCP. You will work with async processing pipelines, a scientific compute layer, and a structured API-first architecture. Specific stack details are shared during the interview process.
Technical:
- Strong Python backend engineering — you have built and shipped production APIs
- FastAPI or equivalent modern Python frameworks
- Cloud-native architectures (AWS, GCP, or Azure)
- Async processing and orchestration pipelines
- PostgreSQL and data-intensive systems
- Docker and container-based deployment
- Infrastructure design for technical or scientific applications
Mindset:
- Senior individual contributor — high ownership, high autonomy
- Strong systems thinker who sees the whole, not just the ticket
- Pragmatic builder capable of balancing speed and robustness
- Comfortable operating in ambiguous, fast-moving environments
- Interested in climate infrastructure, optimization systems, or deep-tech products
- Require highly structured corporate environments
- Prefer narrowly scoped ticket execution
- Are uncomfortable working close to evolving product and technical requirements
- Have no interest in the energy transition or scientific computing domains
- ?? Strategic headquarters in Berlin
- ? Technical and scientific team presence in Argentina
- ? International and interdisciplinary team across energy, engineering, AI, and infrastructure
- ? Connected to the German renewable energy and startup ecosystem, including networks linked to TU Berlin and AHK-Argentina
- Backed by a major German EXIST startup program with 12-month funded runway
- Full-time dedication required — this is a critical path role
- Berlin-based required — the EXIST program requires physical presence in Berlin
- Start ASAP preferred
- Funded through the EXIST program : €2,500 to €3,000/month depending on profile
- Meaningful long-term equity and ownership potential
- High technical influence on platform architecture and product direction
- Introductory conversation
- Technical deep-dive discussion
- Practical architecture and collaboration exercise
- Final mutual fit conversation
