• Partner with business and product stakeholders to translate ambiguous requirements into technical solutions
• Own technical delivery from design through deployment, release management, and post-production support
• Drive automation initiatives that reduce manual processes and operational overhead
• Mentor engineers and influence engineering standards, architecture decisions, and development practices

Qualifications

• Ability to thrive in ambiguous, fast-moving environments

Preferred Skills

• Experience with Temporal, Cadence, AWS Step Functions, or similar workflow orchestration platforms
• Experience building and deploying AI workloads on GCP, including Vertex AI, Gemini, Cloud Run, or GKE
• Experience developing modern web or mobile applications using React, Next.js, React Native, or Expo
• Familiarity with AI observability and evaluation tools such as Langfuse or OpenTelemetry
• Experience with MongoDB, PostgreSQL, vector databases, embeddings, or search technologies
