  • Build secure, compliant, and responsible AI solutions ready for production scale.
  • Contribute to a culture of continuous learning, experimentation, and engineering excellence.
  • Mentor and grow the energetic, diverse, and driven team with a good mix of senior, mid-level, and entry talent.

Preferred Qualifications
  • 6+ years of professional software engineering experience with hands-on coding in languages such as C#, Java, Python, or React.
  • Proficiency in AI-native development - working within Agent Harnesses (GitHub Copilot CLI, Coding Agents), authoring Markdown specs/ADRs and YAML configs as Agent-consumable inputs, orchestrating multi-step Agentic workflows across the SDLC, and reviewing Agent-generated code and PRs with production-grade rigor.
  • Fundamentals in data structures, algorithms, object-oriented design, and scalable systems.
  • Experience building, testing, debugging, and maintaining production-quality software, following established engineering practices as well as leveraging large language models (LLMs).
  • Problem-solving and technical judgment skills, with the ability to design scoped solutions, debug complex issues, and improve service performance.
  • Experience in driving AI (LLM/ML) based engineering solution.
  • Experience with cloud platforms and distributed/service-oriented architecture.
  • Familiarity with reliability, monitoring, and performance optimization practices.
