Posted on behalf of Future Energy Enterprises.


Future Energy Enterprises is seeking a highly motivated and detail-oriented Software Developer to join our growing team. This role is focused on deepening expertise within an established enterprise platform, the California eTRM, and is ideal for a junior/early-career engineer who excels at learning complex systems and mastering backend development. The successful candidate will receive dedicated mentorship and will be put through a technical onboarding program focused on accelerated learning.

This position will support the development and management of the electronic Technical Reference Manual, California's central database for energy efficiency measures.

This role is best suited for someone who enjoys diving deep into existing code and learning the backend architecture thoroughly.


 Responsibilities:

  • Take ownership of the eTRM codebase, focusing on developing, testing, and maintaining features primarily on the backend using Python, Django, and AWS.
  • Quickly learn and become proficient with the enterprise codebase, contributing to platform reliability, security, and performance.
  • Support the development of new eTRM features or eTRM-related products, with a focus on backend architecture and implementation.
  • Collaborate with team members, internal stakeholders, and vendors to translate requirements into high-quality technical solutions, following Agile-Scrum best practices.

  • Contribute to continuous improvement through code reviews, automated testing, and CI/CD practices.


Qualifications:

  • Experience: 3+ years of professional or significant project experience in software development, particularly working with existing, complex codebases (enterprise experience is a plus). We value demonstrated capability and growth potential over years of service.
  • Education: Bachelor’s Degree in Computer Science, Engineering, or a related field (or equivalent practical experience).
  • Back-End Mastery:
    • 3+ years of strong proficiency in Python/Django or other backend frameworks/ORM.
    • 3+ years of deep knowledge of database systems, particularly Postgres DB SQL.
    • 2+ years of experience with REST API design and development.
  • Architecture Foundation: Foundational knowledge of software architecture principles.
  • Full Stack Awareness: Familiarity with full-stack concepts, including React or Next.js.


Preferred Qualifications:

  • Backend & DevOps: Docker, AWS (RDS, S3), CI/CD (Github Actions), Cloudwatch, Celery, Authentication/Authorization (JWT, OAuth2, RBAC), Redis (caching), and an interest in GenAI-assisted development.
  • Testing:
    • Familiarity with Unit tests (Jest, React Testing Library)
    • High-level knowledge of E2E tests (Playwright or similar framework)
  • Additional Technologies: Typescript/JS, CSS.
  • Industry Experience: Energy efficiency or utility industry experience.
