Experience with HIL/SIL/EOL test architectures required. * Production & safety context: demonstrated experience building automation used in factory or safety-critical environments and delivering to production schedules and quality targets. * Measurable delivery record: examples of shipped systems with quantified impact (throughput, yield, defect reduction, reliability improvements) and first-6-to-12-month outcomes you drove. * Operating expectations: comfortable with high-impact deadlines, on-call rotations, and occasional site travel to support installations or production ramps. This is primarily onsite in South San Francisco; you must be able to work from the office regularly. * Authority & collaboration: able to drive cross-functional technical decisions, write clear acceptance criteria, and escalate to program leads when necessary. * Work authorization: Zipline can sponsor visas; candidates should discuss needs during process. ## Description * Own end-to-end delivery of test systems (SIL, HIL, EOLT, bench rigs) from prototype through production deployment and field sustainment. You are the technical owner accountable for schedules, acceptance criteria, and production readiness. * Ship measurable improvements: define and meet targets such as test coverage %, mean time to detect (MTTD) critical failures, reduction in test cycle time (targeted improvements set in first 90 days), and defect escape rate reductions tied to your systems. * Architect, implement, and maintain software that runs and orchestrates test sequences, data capture, analysis, and reporting. Build automation and dashboards used by manufacturing engineers and test operators. * Integrate software with hardware under test: board bring-up, sensor calibration, motion systems, power systems, and DAQ instruments. Validate against datasheets and representative hardware in lab and factory settings. * Lead investigations and root-cause analysis for failures discovered in test or production, produce corrective plans, and drive fixes to closure with engineering and operations stakeholders. * Define and enforce test standards, pass/fail criteria, and validation protocols used across products and production lines. Own CI/validation pipelines that gate changes to flight or manufacturing systems. * Work cross-functionally with embedded firmware, hardware, manufacturing engineering, supply chain, and field ops to deploy test systems at scale; coordinate vendor hardware and field installation when required. * Support on-call and production escalation cadence for systems you own (expect regular production-support rotations and periodic urgent in-factory or field troubleshooting). Travel to manufacturing or distribution sites as required (typical travel up to 20% first year; may spike during launches or product transitions). ## Related Videos - [Code to Road in < 12 hours](https://www.wearedevelopers.com/videos/1082-code-to-road-in-12-hours) - [Mutation Testing and Fuzzing in C#](https://www.wearedevelopers.com/videos/703-mutation-testing-and-fuzzing-in-c) - [How a Small Team Shrank a Microsoft Monorepo by 94%](https://www.wearedevelopers.com/videos/1236-how-a-small-team-shrank-a-microsoft-monorepo-by-94) - [Trunk-Based Development at Scale: Real-World Insights from a High-Traffic Luxury E-Commerce Platform](https://www.wearedevelopers.com/videos/1435-trunk-based-development-at-scale-real-world-insights-from-a-high-traffic-luxury-e-commerce-platform) - [Test-reduction - Doing more with less](https://www.wearedevelopers.com/videos/977-test-reduction-doing-more-with-less) - [Git for Code Reviews](https://www.wearedevelopers.com/videos/429-git-for-code-reviews) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers)
