Senior Software Engineer I

About This Opportunity

We are representing a confidential energy technology client seeking a Senior Software Engineer I to join their Client Engineering team in Paris. This is a hybrid role requiring an existing right to work in France—visa sponsorship is not available at this time.

Our client is working at the intersection of clean energy and intelligent software, building platform solutions that coordinate energy systems at scale. You'll be contributing to production systems used by major enterprise clients across Europe.

Responsibilities

• Hands-on Development: Write clean, well-tested TypeScript code to build and extend platform features for enterprise clients, taking ownership from conception through deployment.
• Cloud-Native Architecture: Build and maintain highly scalable applications on AWS Serverless (Lambda, API Gateway, DynamoDB) and design event-driven microservices with real-time data streaming via Kafka.
• AI Integration: Identify and implement opportunities to embed AI into the platform and development lifecycle—including LLM-powered automation, intelligent decision support, and AI-assisted workflows. Act as an AI knowledge carrier, sharing learnings across teams.
• Technical Leadership: Champion engineering best practices through thorough code reviews and mentor junior engineers on TypeScript, serverless patterns, and AI development approaches.
• Cross-Functional Collaboration: Work closely with Product Managers and Engineering Managers to refine features, estimate tasks, and deliver value predictably.

What We're Looking For

Core Requirements:

• TypeScript Expertise: Strong professional experience building scalable, production-grade applications using TypeScript and Node.js, including AWS Serverless architectures and event-driven systems such as Kafka.
• AI Mindset: Practical approach to AI as an engineering tool—curious about possibilities, focused on production-ready solutions, and motivated to enable colleagues.
• Problem-Solving Track Record: Demonstrated ability to deliver team-level technical expertise on complex application workflows.
• Agile Practices: Solid grasp of CI/CD pipelines, software development fundamentals, and Agile/Lean methodologies.
• Communication Skills: Excellent ability to collaborate cross-functionally and explain technical concepts to non-technical stakeholders.
• Right to Work: Existing authorization to work in France (visa sponsorship not available).

Differentiators:

• LLM Integration Experience: Hands-on experience integrating large language models into production applications via APIs (OpenAI, Anthropic, AWS Bedrock) or open-source models, with understanding of prompt engineering and evaluation.
• AI Tooling Advocacy: Track record of introducing AI-assisted developer tooling (Copilot, Cursor, Claude) into teams and upskilling colleagues.
• Enterprise Domain Knowledge: Background with large enterprise applications involving billing, ledger tooling, payments integration, or energy-related data systems.
• Client-Facing Experience: Previous work on consulting, SaaS onboarding, or client-delivery technical projects.
