How You’ll Make An Impact

• Help shape and deliver the platform that underpins Siemens Energy’s agentic software development lifecycle by translating delivery teams’ needs into reusable services, APIs, and self‑service capabilities.
• Implement essential capabilities such as token budgets, consumption tracking, automated onboarding, LLM routing, and management of agent personas and skills.
• Support forward‑deployed engagements by embedding with software engineering teams, configuring tooling, coding agents and guardrails, and building proofs of concept under the guidance of senior engineers.
• Advance harness engineering through context, tool integrations, execution environments, evaluations, and feedback loops that enable agents to operate reliably within defined boundaries.
• Write, review, test, and ship production code using AI coding tools like Cursor and Claude Code, ensuring the correct application of guardrails and supporting reliable platform operation.
• Capture lessons from real projects to enhance the platform, blueprint, and developer experience while developing your ability to scope and run engagements independently.

What You Bring

• A master’s degree in computer science or a related field, with at least 5 years of professional experience in full‑stack software engineering and a minimum of 2 years in AI‑assisted/agentic software engineering.
• Strong programming fundamentals with flexibility across languages; experience with a statically typed language such as C#, Java, or TypeScript, as well as CI/CD and cloud‑native development, is a plus.
• Practical integration experience connecting systems through APIs or data pipelines, with an understanding of challenges beyond your own code, including authentication, dependencies, and error handling.
• A systems understanding and curiosity about design trade‑offs, such as message queues versus synchronous APIs or relational versus NoSQL databases, along with an interest in reusable platform capabilities and developer tooling.
• Curiosity about and hands‑on experience with AI‑assisted development tools like Cursor, Claude Code, or Copilot, and an interest in agent workflows, context, skills, and evaluations.
• A willingness to embed with teams, learn quickly, and deliver in short cycles, complemented by a collaborative, hands‑on attitude, good communication skills, and growing ownership; fluent English is required, with Spanish being a plus.
• Must be based in Portugal or Spain (mandatory).
