Compensation: $150K – $175K • Offers Equity

Employment Type: FullTime

We are seeking a talented Backend Software Engineer to join our core engineering team. The ideal candidate is a product-minded builder who can own features end-to-end — from scalable backend APIs to beautiful, high-performance interfaces — contribute to architecture and design decisions, and mentor other engineers as we scale a deeply technical product at the intersection of AI and logistics. We’ve found a ton of value and upside in spending time together, so our team works from our SF and NYC offices three days a week.

Key Responsibilities

• Design and build end-to-end features across the stack, integrating backend services and frontend interfaces.

• Develop robust APIs using Python (FastAPI), Go/Rust, integrating with time series data (TimescaleDB), multimodal streaming data (video) and databases (Postgres).

• Collaborate with product, design, and domain experts to prototype, validate, and ship new features rapidly.

• Optimize application performance and observability across backend.

• Contribute to our component libraries, design system, and development best practices.

• Participate in architectural decisions and code reviews to support engineering excellence.

Required Qualifications

• Proven backend experience with Python and Go or Rust in production systems.

• 5+ years of professional experience building scalable, user-facing applications.

• Strong understanding of API design, state management, and asynchronous data flows.

• Proficiency with web frameworks like FastAPI or Flask.

• Experience with relational databases like PostgreSQL (bonus for time-series extensions such as TimescaleDB).

• Experience with developing and deploying in containers (e.g. Docker)

• Familiarity with cloud infrastructure, especially GCP or platform / infrastructure (e.g. k8s, terraform)

• Experience with large-scale video data processing or streaming media services

• Comfortable navigating ambiguous problems and driving projects from 0 → 1.

• Excellent collaboration and communication skills in cross-functional environments.

Preferred Qualifications

• Experience with real-time data visualizations or interfaces tied to robotics, ML, or logistics systems (WMS, TMS, ERP).

• Familiarity with frontend performance tuning, component architecture, and modern styling systems (e.g., Tailwind).

• Experience working in early-stage startups or small teams.

• Exposure to observability stacks (e.g., Grafana, Prometheus, OpenTelemetry).

• Strong design sensibility and product thinking.
