How much do harness engineer jobs pay per hour?

As of Sep 5, 2026, the average hourly pay for harness engineer in the United States is $49.97, according to ZipRecruiter salary data. Most workers in this role earn between $40.87 and $57.21 per hour, depending on experience, location, and employer.

What is a harness engineer?

Harness engineers are professionals who design, develop, and maintain wiring harness systems used to connect electrical and electronic components in vehicles, machinery, or equipment. They are responsible for creating detailed schematics, selecting appropriate materials, and ensuring compliance with industry standards and safety regulations. Harness engineers work closely with other engineering teams to ensure the wiring harnesses meet the specific functional and environmental requirements of the product. Their work is crucial in industries such as automotive, aerospace, and industrial manufacturing.

What are some typical challenges a harness engineer faces when collaborating with cross-functional teams?

Harness Engineers often work closely with design, manufacturing, and testing teams to ensure wiring systems are integrated seamlessly into complex products. A common challenge is managing communication between departments, as design changes can impact harness routing or specifications. Additionally, ensuring that harness designs meet both electrical and mechanical requirements while adhering to tight project timelines can be demanding. Strong organizational and interpersonal skills are crucial for navigating these challenges and delivering effective solutions.

What are the key skills and qualifications needed to thrive as a harness engineer, and why are they important?

To thrive as a Harness Engineer, you need a solid background in electrical engineering principles, experience with wire harness design, and typically a relevant engineering degree. Familiarity with CAD software (such as CATIA or AutoCAD), wiring diagram tools, and industry standards like IPC/WHMA-A-620 is essential. Strong problem-solving skills, attention to detail, and effective teamwork are crucial soft skills for this role. These abilities ensure reliable, safe, and compliant harness designs critical for performance in industries like automotive and aerospace.

What is the difference between Harness Engineer vs Electrical Engineer?

AspectHarness EngineerElectrical Engineer
Required CredentialsBachelor's in Electrical/Electronic Engineering or related field; certifications like IPC/WHMA-A-620Bachelor's or higher in Electrical Engineering; Professional Engineer (PE) license often preferred
Work EnvironmentDesigning and testing wiring harnesses, working in manufacturing or automotive settingsDesigning electrical systems, working in various industries including power, electronics, and manufacturing
Employer & Industry UsageAutomotive, aerospace, electronics manufacturingPower generation, electronics, telecommunications, manufacturing

While both roles require electrical knowledge, Harness Engineers focus on designing and testing wiring harnesses for specific applications like automotive or aerospace, whereas Electrical Engineers work on broader electrical systems and circuitry across multiple industries.

Job description

Harness Engineer
Location: San Francisco (in-person, in-office, full-time ONLY)
Compensation: $150k-$250k base + top of market equity
About Virio
Virio is solving an unsolved problem: how do you write perfect content? The best human strategist researches the space, finds the angle, and knows your goals and constraints - but they're capped by the hours in a day and one human career's worth of expertise. An agent isn't.
Crafting "perfect" content has three components:
1. Research: to identify and collect the best inputs
2. Synthesis: to devise the strategy and execute on it
3. Verification: RL verification of content quality and efficacy
We're backed by operators from LinkedIn, YouTube, HubSpot, Rippling, and Google. The team is almost 100% ex-founders and VCs from Yale, UC Berkeley, Stripe, and more. And we've consecutively added $1M ARR/mo because everyone and their co-founder wants what we're selling.
This problem doesn't have a playbook. We're looking for a Harness Engineer to obsess over AI-for-writing and own that layer end to end: the data feedback loop, evals, and harness design that turn a subjective judgment into something we can measure and improve - so day by day, we can get ever closer to solving content.
What You'll Do
As a Harness Engineer, you'll own the intelligence layer that sits between our AI models and product-the system prompts, tool definitions, context management, and evaluation framework that makes agents actually work in production.
Specifically:
  • Build and refine the system prompts, tool integrations, and context windows that shape how our models behave across our platform-you'll see how small prompt tweaks cascade into measurable product impact. (Nice to have: background in English, literature, creative writing, or humanities)
  • Design the evaluation framework (LLM-as-judge evals, deterministic tests, production monitoring) that lets us ship with confidence. You'll define what success looks like and build the metrics to measure it.
  • Architect the abstraction layer between our product (file systems, artifacts, skills) and the model's capabilities-making complex multi-step workflows feel natural to the model and reliable to users.
  • Own prompt versioning, experimentation, and iteration. You'll A/B test prompt variations, measure their impact on agent quality, and ship improvements across our production system.
  • Collaborate with product and engineering to identify signal-where our agents are failing, where users are stuck-and translate that into prompt and architecture improvements.
What Success Looks Like
  • After 30 days: You understand our agent stack-the system prompts, available tools, context window strategy, and current failure modes. You've shipped your first prompt improvement and measured its impact.
  • After 90 days: You've designed and implemented our core evaluation framework. Our team uses it as the source of truth for agent quality. You've shipped 2-3 meaningful prompt iterations that improved measurable outputs, and you're comfortable making architecture trade-offs.
  • After 6 months: You own the harness layer end-to-end. You've architected improvements that reduced hallucination, improved context retention, or increased model reliability. You're driving architectural decisions about how we expose capabilities to the product team. You're writing technical content about how we've solved these problems-attracting the next generation of harness engineers to the company.

Traits That Thrive at Virio
  • High agency & self-direction - Acts without waiting for requirements or detailed instructions
  • Small-team intensity comfort - Comfortable working intensely and closely with a small, high-output team
  • Unorthodox problem solving - Sees non-obvious paths forward and challenges conventional approaches
  • Quality-driven execution - Detail-oriented with high standards for correctness and quality
  • Low ego & accountability - Takes full ownership and accountability for outcomes

Benefits
  • Work directly with the founders
  • Competitive total compensation aligned to impact and ownership
  • Meaningful equity upside as part of the founding team
  • Medical, dental, and vision insurance
  • 401(k) plan
  • All working meals covered
  • Relocation support for San Francisco
  • Company-wide annual off-site
  • High ownership, high trust, and fast career progression alongside world-class client partners
  • In-person culture with deep commitment to excellence

This is a full-time, on-site role based in San Francisco. We do not offer hybrid or remote positions.
