About the job

Why Nuclearn.ai

Nuclearn.ai builds AI-powered software for the nuclear and utility industries—tools that keep critical infrastructure reliable, efficient, and safe. Our software integrates AI-driven workflow, documentation, and research automation, and is already used at 60+ nuclear reactors across North America. You'll ship production code operators and engineers rely on every day.

We're growing quickly, expanding our team and our Phoenix HQ. The work is consequential: what you build helps real plants run safer and smarter.

Eligibility: U.S. citizenship or permanent residency (green card) is required due to DOE export compliance.

What You'll Do

• Implement, test, and maintain API-based integrations between the Nuclearn platform and client systems.
• Serve as the primary technical point of contact for clients during integration projects.
• Translate client requirements into actionable technical solutions.
• Support and troubleshoot integration pipelines, ensuring reliability and scalability.
• Document integration processes and create clear client-facing technical guides.
• Develop and maintain out-of-the-box integration solutions for CAP-AI customers to accelerate adoption and reduce custom setup effort.

Examples of problems you might own in your first 90 days

• Build a DevonWay → CAP-AI connector that ingests event data in tabular form, validates against our schemas, and supports safe reprocessing.
• Add a “simulate, then apply” workflow for CAP automations (human-in-the-loop gates, dry-run diffs, full audit trails, easy rollbacks).
• Package and release an out-of-the-box integration template for new CAP-AI customers.

What Makes You a Great Fit

• Degree in CS or related field or equivalent practical experience.
• Proficiency in Python, SQL.
• Strong experience with REST APIs and integration workflows.
• Familiarity with Linux environments and containerization (e.g., Docker).
• Excellent communication skills; able to explain technical concepts clearly to clients.

Nice To Have (not Required)

• AI/ML or data-pipeline experience (prompting, retrieval, feature stores, vector search).
• Prior startup experience.
• Exposure to nuclear/utility or other safety-critical domains (aviation, med-device, rail, etc.).

Impact You'll Have (near-term roadmap)

• CAP-AI “toward 100% automation”: design safe guardrails (review gates, audit, simulation modes).
• Data connectors: unstructured PDFs, structured feeds; resilient syncs with Maximo/DevonWay; M365 integrations.
• Performance & reliability: fewer flakes, faster jobs, clearer dashboards, calmer alerts.

How We Hire (fast, respectful, practical)

1. 20-min intro with the founder/hiring manager to trade context and assess mutual fit
2. Practical work sample (60–90 min; a real task in our stack)
3. Team meet + peer programming (system design + collaboration)
   We aim to move from first chat to decision quickly.
