the lottery is wage-weighted — each level is one more entry
$29,355 more — $194,355 — moves this role to Level IV and 4 lottery entries. That figure is inside the range the employer already advertised.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $194,355 would place this position at wage Level IV. That figure is within the posted range, and I'd like to target it. This role classifies under "Engineers, All Other" for prevailing-wage purposes.
DOL prevailing wage, 2026-27 wage year · Engineers, All Other (17-2199) · San Francisco-Oakland-Fremont, CA. Wage level is derived by USCIS from the offered wage, occupation and worksite; the occupation shown is inferred from the job title.

About the role
- This includes test automation frameworks, CI pipelines, aerosol science instruments, electromechanical fixtures, and the software that ties it all together.
- If you're equally comfortable writing a Python test harness and assembling a precision fixture, you'll fit right in.
- Team Snapshot - Small team, real ownership.
Responsibilities
- Work cross-functionally with Firmware, Product Design, Chemistry, and Regulatory teams to translate program needs into reliable, well-documented tooling.
- Design and develop test systems and automation tooling. This includes software frameworks, electromechanical fixtures, and instrumentation.
- Contribute to the team's CI/firmware testing infrastructure by developing modular, maintainable test platform components in close collaboration with the firmware engineering team.
- Consistently produce clear, thorough documentation that enables peers and stakeholders to self-serve and build on your work.
- Actively leverage AI coding assistants and LLMs as a first-order productivity multiplier for code generation, debugging, documentation, data analysis, and design iteration.
- Small team, real ownership. You won't just be assigned a slice of someone else's project; you'll own yours from kickoff to deployment, with the trust and visibility that comes with it.
- Broad by design. The work spans mechanical design, electronics, embedded systems, instrumentation, and software. You're expected to be useful across all of them.
- What you build, people use. Firmware engineers, aerosol scientists, and regulatory teams depend on this team's output. You'll always know exactly who you're building for and why it matters.
- AI-first, for real. Between test data, automation pipelines, and embedded tooling, there's no shortage of places to apply it. We're actively building that culture and this hire will help drive it.
- The Internal Tools team builds the infrastructure that Juul's hardware and firmware programs run on.
