The role requires sound judgment, composure, strong relationship skills, cross-functional coordination, and effective use of AI tools. It also contributes to team morale, culture, and executive effectiveness in a fast-paced environment.

Hardware systems engineering intern supporting system design, validation, testing, prototyping, troubleshooting, and preparation of electro-mechanical products for mass production. The role involves building test setups, using lab equipment and CAD tools, collaborating with firmware and product design teams, and analyzing system performance. Candidates should be pursuing or have completed an engineering degree and understand manufacturing processes, material selection, rapid prototyping, and 3D CAD.

Own Mill’s paid customer acquisition engine across consumer and commercial business lines. Manage channel strategy, budgets, bidding, pacing, attribution, CAC/LTV modeling, experimentation, creative testing, conversion optimization, and lead generation. Partner with Growth, Analytics, Creative, Sales, Product, and Operations to improve efficiency, diversify channels, hit performance targets, and build a repeatable growth playbook.

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.

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.

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.
