  • Collaborate with cross-functional teams to understand business requirements and deliver high-quality technical solutions.
  • Develop AI systems that meet privacy, security, and regulatory requirements.
  • Integrate machine learning solutions into existing platforms, infrastructure, and business workflows.
  • Troubleshoot technical, data, and deployment issues across the ML lifecycle.
  • Contribute to engineering best practices, reusable frameworks, internal tooling, and MLOps processes.
  • Communicate technical concepts, trade-offs, and project progress to both technical and non-technical stakeholders.
  • Stay up to date with advancements in AI, machine learning, and software engineering, applying new technologies where appropriate.
  • Senior Engineers: Provide technical leadership, mentor team members, contribute to solution architecture, and drive engineering excellence across projects.

What We’re Looking For

Required Qualifications

  • Bachelor’s or Master’s degree in Computer Science, Mathematics, Statistics, Engineering, Physics, or a related STEM discipline (or equivalent practical experience).
  • Mid-Level: 3+ years of experience in Machine Learning, Artificial Intelligence, Data Science, or Software Engineering.
  • Senior: 5+ years of relevant industry experience with demonstrated ownership of production AI/ML systems.
  • Strong Python development skills with a focus on writing clean, maintainable, well-tested, and well-documented code.
  • Experience developing and deploying machine learning or AI solutions in production or near-production environments.
  • Experience building applications powered by Large Language Models (LLMs), Generative AI, or AI evaluation frameworks.
  • Experience with cloud platforms and modern MLOps practices, including model deployment and monitoring.
  • Strong knowledge of Linux, Docker, Git, CI/CD pipelines, and containerized application deployment.
  • Experience across the complete ML lifecycle, from experimentation and prototyping to production deployment.
  • Experience building data pipelines, APIs, or AI-enabled applications.
  • Strong analytical and problem-solving skills with the ability to work in dynamic, collaborative environments.
  • Excellent communication skills and the ability to explain technical concepts to both technical and non-technical stakeholders.

Nice to Have

  • Experience working in privacy-focused, secure, or compliance-sensitive environments.
  • Experience delivering AI solutions within regulated industries such as financial services, insurance, healthcare, or the public sector.
  • Experience collaborating with external partners, research organizations, or academic institutions.
  • Familiarity with agentic AI architectures, Model Context Protocol (MCP), Agent-to-Agent (A2A) communication, or inference-time privacy techniques.
  • Experience using AI-assisted development tools such as GitHub Copilot, Claude, Claude Code, Cursor, or similar developer productivity tools.
