Job description

Soldera is the "Stripe for Renewable Energy." We are an AI-native metalayer automating the fragmented, €13B European renewable energy certificate market.

The Traction: In 2025, we executed a breakout year: revenue scaled from €13k to €1M with consistent 30% MoM growth. We are backed by Lifeline Ventures, Lemonade Stand, and a fresh €1.6M deep-tech grant to unify Europe's energy registries. We serve Fortune 500s and manage 4,000+ power plants.

The Mission: We are not just building a dashboard. We are building the autonomous infrastructure that buys, sells, and retires green energy certificates across 30+ disconnected national registries. We need a Senior Engineer who combines product intuition with deep AI engineering skills to build the "brain" that makes this happen.

The Role: AI-Native Engineering

We believe the future of software engineering is AI-augmented. We care about how fast you can ship reliable, scalable value by leveraging AI.

If you are a purist who refuses to use Copilot or Cursor, this role is not for you.If you are a pragmatic builder who uses LLMs to multiply your output by 10x, welcome home.

What You Will Build:

• Autonomous Trading Agents: Design and ship AI agents that navigate legacy government portals (some typically require Excel/Email) to execute trades autonomously.
• Unstructured Data Pipelines: Build resilient systems that ingest messy data (PDFs, scanned docs, varied API formats) from 30+ countries and normalize it into a pristine global standard using LLMs and OCR.
• The Metalayer API: Architect the single API that allows a global asset manager to trade in 15 regions instantly.
• Product Velocity: Work directly with the founders to prototype, ship, and iterate on features weekly.

What We Need

• Senior Engineering Chops: 5+ years of shipping production software (TypeScript, Node.js, Python, PostgreSQL). You know how to structure a codebase that survives scaling.
• AI Implementation Experience: You have moved beyond "calling the OpenAI API." You understand RAG, structured outputs, agentic workflows (LangChain/LangGraph), and prompt engineering as a discipline.
• Product-First Mindset: You don't wait for a ticket. You understand the business goal (e.g., "reduce onboarding time by 50%") and you figure out the technical solution.
• Tooling Obsessed: You are fluent in AI coding tools (Cursor, GitHub Copilot, v0, etc.). You view coding as "architecting logic," not typing syntax.
• High Agency: We are a small, elite team of 11. There is no bureaucracy. You see a problem, you fix it.

The Tech Stack

• Core: TypeScript, Python, Vue, Flask
• AI/Data: OpenAI/Anthropic APIs/Gemini, LangChain, Vector Databases
• Infrastructure: AWS/GCP, Docker, Terraform

Why Join Soldera?

• The "PayPal Mafia" Effect: Work alongside ex-Bolt, Wise, LHV, and Sixfold talent. We are building the next Estonian unicorn, and the early team is the most critical.
• Freedom & Responsibility: We don't track hours. We track shipping. You have the autonomy to choose the best tools for the job.
• Significant Upside: We offer a competitive senior salary and a significant equity package. We are capturing an $80B market; your options are designed to be life-changing.
• Impact: You are literally building the digital infrastructure that accelerates Europe’s transition to renewable energy and increases energy security.
