Job description

Position Overview
We are partnering with an innovative, data-driven technology company to find a Senior Full Stack Engineer with a heavy emphasis on backend architecture, APIs, and cloud systems. As a key hands-on technical contributor, you will help build and scale an analytical platform during a major expansion phase. This role requires strong systems thinking and a focus on data-intensive applications, backend stability, and modern cloud deployment.
(Note: This is an individual contributor, hands-on role without direct reports, offering a hybrid work model with an on-site requirement in Oakland, CA from Tuesday through Thursday).
Key Responsibilities
  • Design, develop, and maintain robust, scalable, and secure backend systems, data pipelines, and high-performance APIs using Python and FastAPI.
  • Own data migration initiatives (utilizing tools like Dagster and DuckDB) while maintaining system reliability and operational continuity.
  • Architect and manage cloud infrastructure on Microsoft Azure, supporting containerized services and data-intensive workflows.
  • Integrate advanced capabilities, including AI-hosted chatbots and LLM-driven tools, into cloud-native analytical systems.
  • Partner closely with Product and Delivery teams to translate business needs into robust, production-ready features.
  • Drive long-term technical architecture, manage system versioning, and actively minimize technical debt.
Qualifications & Requirements
  • Education: Bachelor's or Master's degree in Computer Engineering, Computer Science, or a related technical field.
  • Experience: 5 to 7 years of professional full-time software engineering experience.
  • Core Tech Stack:
    • Strong, non-negotiable proficiency in Python and backend development (FastAPI).
    • Solid database experience with PostgreSQL.
    • Cloud computing proficiency (Azure preferred, or AWS/GCP) along with containerization (Docker).
    • Experience building and deploying high-performance APIs.
  • Systems Mindset: Proven track record of system design, data-intensive architecture, and managing complex migrations.
  • Bonus / Preferred Experience:
    • Background in energy systems, carbon analytics, sustainability, or healthcare.
    • Early-stage startup or new venture experience building products from scratch.
    • Familiarity with Dagster, DuckDB, Infrastructure as Code (Terraform/Bicep), and AI/LLM integrations.
Work Environment & Logistics
  • Location / Schedule: Hybrid model based in Oakland, CA, requiring on-site presence from Tuesday through Thursday.
  • Role Type: Full-time, hands-on individual contributor position.
