Job Description

CommanderAI is building the go-to revenue engine for the $100B+ waste and recycling industry. We help haulers find, win, and keep more business using AI-driven data, automation, and a sales workflow built specifically for this market.

We are looking for a high-impact Data Science & Backend Engineer with 2-3+ years of experience to join us onsite at our corporate office in Marina Del Rey, CA. You will own core systems work - data modeling, API design, and infrastructure - while also bringing hands-on data science chops to the table. This is a role where backend engineering and applied data science meet.

What you'll do

  • Architect Core Systems: Design and maintain complex data models - including schema design, relationships, indexing, and query performance - to identify and remove friction points.
  • Build & Optimize: Develop APIs and work closely with AI/ML pipelines to ensure seamless lead-to-revenue tracking.
  • Lead Data Science Experiments: Get your hands dirty building models, running experiments, and turning raw data into production features.
  • Own the Lifecycle: Manage the full path from raw data to production feature, partnering with Product and Sales to ensure high-quality outcomes.
  • Collaborate & Scale: Work on a product where the problem space is evolving weekly and your code ships fast to drive real-world ROI.
  • Bring the Market Inside: Relay technical feedback and feature requests to leadership to help shape the product roadmap.

What we're looking for

  • Experience: 2-3+ years of backend development experience (Python, Ruby/Rails, or Node.js), including 2+ years experience building data science learning models.
  • Data Modeling Expert: Strong skills in schema design, relationships, indexing, and query performance.
  • Applied Data Science: Hands-on experience building, training, and evaluating models - regression, classification, clustering, or similar - not just consuming APIs.
  • Technical Stack: Proficiency with Python data science tooling (pandas, scikit-learn, NumPy, or similar) and solid experience with PostgreSQL or similar relational databases.
  • Systems Minded: Comfort with REST API design and building services that other teams depend on.
  • Infrastructure: Familiarity with cloud infrastructure (GCP, AWS, or similar) and keeping data clean.
  • Rapid Self-Starter: You don't need hand-holding; you show up prepared and run your area like a business.
  • Strong Communicator: Ability to simplify complex AI tech into practical terms for the business.

Nice to have

  • Experience with NLP, embeddings, or LLM-based workflows.
  • Exposure to vector databases or ML serving infrastructure.
  • Background in multi-tenant SaaS architecture.
  • Experience deploying models into production (not just notebooks).

Why CommanderAI

  • Category Momentum: Waste and recycling is modernizing fast, and you'll help build the dominant platform in the space.
  • Real-World Impact: You're helping haulers win business, grow routes, and create jobs through applied AI.
  • Ground-Floor Seat: Join a tight, high-caliber, fast-paced team early, help shape the playbook, and grow as we scale.
