Lead technical design and delivery of full‑stack web applications. Write and maintain high‑quality code across frontend and backend, design scalable APIs, use AI‑assisted development tools, mentor junior engineers, run code reviews, champion testing and CI/CD, and collaborate with product and hardware teams to troubleshoot and optimize production systems.

Build and maintain scalable production data pipelines, infrastructure, warehouse models, analytics platforms, and data-quality systems. Partner with software engineers to instrument product features and ensure reliable event data. Support Hex and Snowflake self-serve analytics, maintain business metrics and data logic, and develop monitoring, validation, alerting, and observability tooling. The role also collaborates with product, analytics, marketing, and engineering teams, with potential future exposure to recommendation and LLM-based product work.

As a Product Design Engineering intern, you'll support design and testing of new products, develop prototypes, and work on CAD documentation.

Own modeling and training infrastructure for commercial food-waste CV: train/evaluate segmentation, classification, and mass-estimation models; optimize and deploy edge models; build eval harnesses, annotation tooling, and dataset workflows; analyze failure cases and partner with MLOps/edge engineers to productionize models.

Manage operational accounting and reporting, including GL reconciliations, inventory and fleet accounting, equity and stock‑based compensation, AP and accruals. Draft technical accounting memos, strengthen internal controls, liaise with auditors and cross‑functional teams, and build out the accounting team and automated reporting processes.

Technical individual contributor leading full-stack project architecture and delivery. Write and review code across frontend and backend, design scalable serverless/microservice systems, optimize APIs and databases, use AI-assisted tooling daily, mentor engineers, partner with product, and champion testing, CI/CD, performance, and security best practices.

Design, build, and maintain scalable data pipelines and a customer-facing recommendation engine (including LLM logic). Manage data warehouse, data quality monitoring, CI/CD for pipelines, and partner with product, analytics, engineering, and marketing to ensure consistent metrics and observability.

The Hardware Systems Engineer will lead interdisciplinary projects on the development and optimization of Mill's food recycling technology, focusing on system performance and collaboration with various engineering teams.

Lead and grow a small firmware team while contributing hands-on to MCU firmware design and implementation. Develop wireless connectivity, OTA, sensor integration, and communication stacks. Debug, test, and optimize low-level code and hardware interfaces (GPIO, I2C, SPI, UART). Collaborate with cloud, mobile, product, and hardware teams to ensure production readiness and reliability; recruit, review code, and set technical roadmaps.

Lead the commercial hardware product roadmap from development through launch and post-launch iterations. Define requirements, prioritize tradeoffs, coordinate Engineering, Ops, Design, and Sales, synthesize field and customer feedback, track metrics, and drive product decisions to ensure cost, reliability, serviceability, and user experience goals are met.
