We’re Tovala, a food-tech company reinventing home cooking through hardware, software, and fresh food delivery
We’re hiring a Senior Firmware Engineer to help raise the bar on the connected oven at the heart of every Tovala kitchen
You’ll partner with our firmware lead (5+ years on the team) as a true peer and own meaningful slices of the fleet end-to-end
We run two oven fleets in parallel: a mature legacy fleet, built on the Electric Imp stack coded in Squirrel powering most of our installed base, and a new fleet built on our in-house IoT stack, utilizing ESP32, C and AWS
You’ll focus on keeping the legacy fleet healthy and de-risking changes, while contributing to the new fleet as it grows
AI-assisted development is reshaping how our team works, and we expect the same on firmware
You should have hands-on experience with tools like Claude Code, Cursor, or Copilot and strong opinions on applying them well in embedded contexts where the constraints differ from typical web/backend work
Design, build, test, and ship firmware for our connected ovens — starting with the Electric Imp / Squirrel fleet that serves the majority of our customers today, and contributing to our new ESP32 based platform as it scales
Own bug fixes, feature additions, and performance/efficiency improvements end-to-end — from scoping through lab testing, staged fleet rollout, and production monitoring
Write, monitor and maintain automated firmware test pipelines
Design and execute test plans on the bench and on real fleet subsets. We push firmware to tens of thousands of ovens in customers’ kitchens, and we take that seriously
Use AI-assisted development tools as a core part of how you work — for code generation, debugging, test scaffolding, log analysis, and documentation — while applying the judgment that embedded work demands
Collaborate closely with our thermal, mechanical, and quality engineers, our manufacturing and ops partners, and our backend team to root-cause issues that span the full stack — firmware, hardware, cloud, and the factory floor
Help evolve our firmware development practices: code review standards, test infrastructure, release processes, and how we incorporate AI tooling responsibly
Document and communicate clearly so your work is durable, your tradeoffs are visible, and your teammates can build on top of what you ship
Preferred experience
Comfort working with (or willingness to quickly learn) the Squirrel programming language and the Electric Imp platform
Experience with common embedded interfaces and protocols: I2C, SPI, UART, and the network stacks (BLE, Wi-Fi, TLS, MQTT/HTTPS) that connected products depend on
Strong fundamentals in C/C++ and embedded systems — RTOS, memory, timing, interrupts, real-time constraints, and the discipline that comes with code running on devices you can’t easily reach
Solution-Minded: You focus on outcomes, not output. You want to understand the customer problem before you start writing firmware, and you’re not precious about your approach if a better one emerges
Curious and Adaptive: You stay current on hardware, firmware, and AI tooling, and you have a favorite microprocessor brand — maybe even a favorite oscilloscope brand
Experience working in Python, Bash for build tooling as well as testing automation
A degree in computer engineering, computer science, electrical engineering, or commensurate experience
AI-Forward: You see AI tools as a fundamental shift in how software — firmware included — gets built. You’re already using them daily and have thoughts on how teams should adopt them in safety-conscious, hardware-adjacent contexts
Experience with CICD and automated test workflows, ideally Github automations and workflows.
Strong problem-solving instincts — you dig into root causes, think about second-order effects, and find pragmatic solutions in messy real-world systems
Cross-Functional Collaborator: You thrive working alongside hardware, thermal, quality, manufacturing, ops, and backend teammates. You communicate clearly and care about the end-to-end product experience
Excellent communication skills. You can explain technical decisions and tradeoffs clearly to engineers, hardware partners, and non-technical stakeholders, and you write things down
5+ years of professional firmware or embedded software engineering experience, including shipping firmware to a fleet of internet-connected devices in production
Startup Mindset: You’re comfortable in an environment where priorities evolve and where your work has direct, visible impact on customers’ kitchens
Demonstrated, hands-on experience with AI-assisted software development. You’ve integrated AI tools into your daily workflow and can speak concretely about how they’ve changed the way you build, test, and debug firmware
Manufacturing and factory tooling: Experience building or supporting the systems that flash, provision, and verify firmware on the production line, and debugging them remotely with overseas manufacturing partners across time zones
Familiarity with web technologies both front end and back end as well as databases — Typescript, React, Flask, Go, SQL
Experience with ESP32 and modern embedded toolchains (ESP-IDF, FreeRTOS)
Direct experience with Electric Imp OS and Squirrel
Experience with cloud IoT infrastructure — AWS IoT Core, device shadows, OTA pipelines, telemetry ingestion — even at a contributing rather than owning level
Experience working in a connected consumer product or food-tech company
Hardware-adjacent skills: For example, ability to read schematics and PCB layouts, comfort on a bench with an oscilloscope and logic analyzer, ability to spec an alternate component, basic familiarity with switch-mode power supplies
