🌊🌊Help Scale Climate IoT — Electrical & Embedded Systems Engineer (Contractor) 🌊🌊
Remote (U.S.) · 10–20 hrs/week
About Subtidal
Subtidal, a Woods Hole Oceanographic Institution (WHOI) spin-out, provides turnkey marine & freshwater sensing integrated with cloud analytics. We envision a future where our oceans and waterways become a powerful ally in reversing climate change—enabled by real-time data to scale carbon removal, support human climate adaptation, and protect ecosystems worldwide. Subtidal is backed by leaders including NOAA, the National Science Foundation, the Department of Energy, and Schmidt Marine Technology Partners.
Why This Role Matters
Build core technology that directly advances climate mitigation, community resilience, and nature protection. You’ll inherit a clean, scalable Rust firmware codebase and modern electrical design—recently refactored by a world-class IoT firm—and extend it to support new marine, freshwater, and optical sensors and product features. This role is ideal for a high-drive engineer who enjoys taking ownership of both firmware and electrical design—from embedded code to PCB schematics—and who has experience engineering and scaling consumer IoT products. You’ll thrive here if you’re excited to build innovative solutions for climate resilience and nature, all within a flexible, side-project-friendly cadence.
How to Apply:
We will only be reviewing candidates who email us directly.
Please send your resume and a brief note (a short cover letter or paragraph is fine) about your relevant experience, availability, and why this role excites you to hiring@subtidal.com.
What This Role Offers
- Impact with autonomy: Own firmware + electrical engineering projects end-to-end that ship to production and field deployments, directly advancing climate resilience and ecosystem health.
- Flexible cadence: Variable hours with predictable weekly touchpoints; designed to pair well with a full-time role.
- Modern stack: Production Rust with Embassy (firmware), KiCad schematic and layout, STM32 MCU, Blues Wireless connectivity, low-power IoT design, sensor integrations, field reliability.
- Mission alignment: Your work directly supports climate action and the health of our oceans, rivers, lakes, and ecosystems.
Key Responsibilities
- Maintain and evolve embedded firmware (primarily Rust) and electrical systems to add sensors/features.
- Design, modify, and review PCB schematics & layouts; lead bring-up, validation, and DFM reviews with an eye toward manufacturability and scale.
- Engineer electrical systems for scalability, ensuring smooth transition from a handful of pilot projects to thousands of cloud-connected buoy deployments.
- Integrate marine, freshwater, and optical sensors; collaborate with science & hardware teams on requirements and testing.
- Troubleshoot and harden systems for reliability, low power, and field robustness; write clear documentation.
What We’re Looking For
Requirements:
- U.S.-based, with availability for ~10–20 hours/week (variable).
- 3+ years of experience in embedded systems development and PCB design (IoT and/or sensor platforms strongly preferred).
- Strong proficiency with microcontrollers, digital/analog circuits, and firmware development (C/C++ or Rust).
- Schematic design and PCB layout.
- Experience with hardware bring-up, debugging tools, and version control (Git).
- Ability to work independently in a contractor setting, manage priorities, and communicate clearly.
- Proven track record owning end-to-end delivery of scaled consumer IoT or connected products.
Nice to Have:
- Rust for embedded (or enthusiasm to ramp).
- Field deployments in harsh environments; familiarity with marine, freshwater, and optical sensors.
- Interest in water quality, climate tech, and ocean/marine systems.
