Full-Stack Software Engineering Intern

The Role

We are hiring a Full Stack Software Engineer Intern to work on real, high‑impact problems within our software and operations team. You will contribute directly to building internal tools and systems that support the engineering, construction, and operation of critical infrastructure.

This role is designed to provide hands‑on experience shipping production‑quality software. You will work closely with engineers and cross‑functional stakeholders to build systems that solve real operational problems — not just prototypes or isolated features.

• Own a defined project with clear deliverables by the end of the internship
• Build full‑stack features across frontend (React or similar) and backend services
• Develop and maintain APIs, services, and data integrations
  
  Work with internal stakeholders to understand workflows and translate them into software
• Contribute to internal tools that improve efficiency of engineering and operations teams
• Integrate with third‑party tools and systems (APIs, data pipelines, etc.)
• Collaborate with ML engineers to support data pipelines or ML‑powered features where relevant
• Test, debug, and iterate on production systems
• Present your work, impact, and learnings at the end of the internship

• Currently pursuing a degree in Computer Science, Software Engineering, or related field
• Strong programming fundamentals (Python, JavaScript/Type Script, or similar)
• Familiarity with web development (frontend frameworks and backend basics)
• Hands‑on experience through projects, coursework, or internships
• Ability to break down problems and build end‑to‑end solutions
• Comfortable working in ambiguous environments and learning quickly
• Clear communication skills and willingness to collaborate across teams
