Full Job Description
đź“‹ Description
- • This is a backend and infrastructure engineering role at an early-stage B2B SaaS company in the commercial battery storage and renewable energy space.
- • The platform runs physics-based simulations that help installers, wholesalers, and distributors size, plan, and sell large-scale battery projects — replacing manual spreadsheet work with precise, data-driven proposals covering peak shaving, arbitrage, grid services, and more.
- • Each simulation compares hundreds of battery configurations across multiple application scenarios, producing millions of data points per run.
- • Compute demand is growing on three axes simultaneously: more users, higher usage per user, and increasingly complex simulations.
- • The company is operating in a market doubling year-over-year, with customers across six European countries — and the goal is to scale the customer base by at least 100x.
- • You will be the owner of the entire backend and infrastructure.
- • This is a high-autonomy, high-ownership role at a company that moves fast, minimises meetings, and makes real architectural decisions.
- • The role involves owning and evolving the full backend and infrastructure stack end-to-end.
- • Ensuring service reliability, security hardening, and robust monitoring across all production systems.
- • Scaling compute-heavy simulation workloads to support a rapidly growing user base.
- • Designing and implementing backend architecture for high-throughput, numerically intensive applications.
- • Managing containers, orchestration, queues, and cost control as the system scales.
- • Optimising performance and compute costs continuously, balancing engineering correctness with shipping speed.
- • Making and owning architectural decisions — including whether the current Python-based engine should be rewritten in another language.
- • Supporting new product features and new types of battery application scenarios as the product roadmap expands.
🎯 Requirements
- • 5+ years of experience owning and scaling production backend systems under real-world load.
- • Hands-on experience with web application infrastructure scaling: containers, orchestration, queues, monitoring, performance optimisation, and cost control.
- • Proficiency in Python, or a strong willingness to work in Python while driving architectural decisions (including potential rewrites).
- • Experience designing backend architectures for compute-heavy, numerically intensive applications.
- • Proven ability to work independently, own projects end-to-end, and make sound architectural decisions with incomplete information.
- • Experience with service reliability, security, and production monitoring.
- • Comfort with the pace and ambiguity of an early-stage startup environment.
- • Fully integrated use of AI tools in your development workflow — with the ability to debug and reason independently when needed.
🏖️ Benefits
- • Base salary: €110,000 – €150,000 per year.
- • Equity: 0.5–2.5%, standard 4-year vesting with a 1-year cliff.
