Now, here's what we're building, and where you come in.

We're looking for an Associate Software Engineer to join our Embedded Development team. This is a small, high-performance team within a fast-growing organization where you'll have real ownership and responsibility from day one. You'll ramp up quickly, work across a broad and interesting tech stack, and have a direct impact on hundreds of thousands of physical devices in the hands of frontline workers.

Our technology spans cellular communication, embedded systems, voice processing, Linux, AOSP, app development, and AI - giving you broad exposure that's rare at the associate level. This is a great opportunity for someone early in their career who's genuinely excited about how hardware and software come together, and who wants to solve real problems for real people.

• Collaborate closely with device, QA, platform suppliers, external companies, and third-party contractors to identify and resolve hardware and software issues.
• Build and maintain tooling to isolate and reproduce common application issues, accelerating debugging across internal and external teams.
• Work with a team to bring up new embedded products.
• Improve the efficiency of test and development processes across the organization.
• Write and execute black-box tests against both hardware and software systems.
• Work across a wide range of technologies and programming languages as the product evolves.

• B.S. in Computer Science, Mathematics, Physics, or a related field.
• Familiarity with Linux and embedded systems environments.
• A self-starter mindset with a genuine curiosity about how hardware and software systems work - and fail.
• Strong organizational skills and the ability to manage your own workload with minimal oversight.
• Clear, effective communication skills - including the ability to translate complex technical concepts for non-technical stakeholders - and a collaborative approach to working across teams. 

• Experience with Android development or familiarity with AOSP.
• Exposure to cellular technologies or mobile network protocols.
• Familiarity with scripting languages (Python, Bash, or similar) for test automation.
• Experience writing or executing test cases for embedded or hardware systems.
• Prior work with any version control or CI/CD tools (Git, Jenkins, etc.).
