About Hark
Hark is an artificial intelligence company building advanced, personalized intelligence. One that is proactive, multimodal, and capable of interacting with the world through speech, text, vision, and persistent memory.
We're pairing that intelligence with next-generation hardware to create a universal interface between humans and machines. While today's AI largely operates through chat boxes and decade-old devices, Hark is focused on what comes next: agentic systems that interact naturally with people and the real world.
To get there, we're developing multimodal models and next-generation AI hardware together - designed from the ground up as a single, unified interface for a new era of intelligent systems.
About the Role
We are looking for a hands-on System Validation Engineer to join our growing team. In this role, you will be a key contributor in our hardware lab, rigorously characterizing our system's performance, flagging issues early, and building the automated test infrastructure that will help us scale.
As a System Validation Engineer, you will be the critical bridge between our hardware and software. You will champion the end-user experience by ensuring our systems work flawlessly together.
Responsibilities
- Define, measure, and document key system performance metrics, with a strong focus on power consumption, system latency, and overall stability.
- Rigorously test iterative hardware and software releases, tracking regressions and validating performance improvements over time.
- Ensure Hark's hardware designs integrate seamlessly with software. Proactively test real-world use cases to identify, expose, and document system-level bottlenecks before they reach the user.
- Design, build, and maintain automated test setups to streamline repetitive testing processes, improve reliability, and increase overall test coverage.
- Meticulously track and document bugs. Work closely with the design team to triage issues, diagnose root causes at the system level, and verify fixes.
- Partner effectively with diverse teams across the company—including Wireless, Audio, and UX—to validate holistic system performance and ensure product excellence.
Requirements
- Proven hands-on experience in system-level hardware/software validation. You must be comfortable profiling power, diagnosing latency bottlenecks, and troubleshooting complex system interactions.
- Comfortable reading and working with hardware schematics. Hands on with common hardware lab tools. Working knowledge with Qualcomm chipsets and platforms.
- Solid background in firmware bring-up and experience working within RTOS, Linux, or Android environments.
- Strong programming skills in Python, C++, or LabVIEW. You should be able to write scripts to control standard laboratory test equipment, and/or build simple test jigs.
Bonus Qualifications
- Expertise in one of the following subsystems: camera and optical sensor, capacitive sensor, audio, wireless.
- Familiarity with Agile development processes, bug tracking tools (e.g., Jira), and version control.
Compensation
The US base salary range for this full-time position is between $120,000 - $300,000 annually.
The pay offered for this position may vary based on several individual factors, including job-related knowledge, skills, and experience. The total compensation package may also include additional components/benefits depending on the specific role. This information will be shared if an employment offer is extended.

Integration Engineer Jobs in California: Frequently Asked Questions
How do you become a integration engineer in California?
Most integration engineer roles in California require a bachelor's degree in computer science, information systems, or systems engineering, followed by hands-on experience with integration platforms and APIs. California does not issue a state license specific to integration engineering, so hiring decisions focus on demonstrated technical skills and recognized certifications from vendors such as MuleSoft, AWS, or Microsoft Azure. Building a portfolio of integration projects and targeting associate or junior integration developer roles at California technology companies or large healthcare systems is the most direct entry path.
How much do integration engineers make in California?
Integration engineers in California earn a median of about $130,850 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $74,950 for the lowest 10% to over $212,130 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire integration engineers in California?
Employers hiring integration engineers in California right now include Apple, Tesla, and Northrop Grumman, based on current listings on Migrate Mate as of November 2026. California's concentration of enterprise software companies, large healthcare networks, and aerospace and defense contractors means steady integration engineering demand well beyond the major tech campuses.
Which California cities have the most integration engineer jobs?
San Diego, Palo Alto, and El Segundo have the most integration engineer openings in California. The Bay Area's density of enterprise software and cloud companies drives the largest share of postings, while Los Angeles draws demand from media, healthcare, and defense contractors, and San Diego's biotech and defense sectors anchor hiring in the south.
Are there remote integration engineer jobs in California?
Yes, and more than most technical fields. About 48% of integration engineer openings tied to California are remote or hybrid as of November 2026, reflecting how much of this work involves configuring cloud platforms and writing API logic rather than being on-site. The roles most likely to stay fully remote are cloud integration and iPaaS implementation work, while on-premise ERP and industrial system integration typically require a physical presence.
How can I get hired as a integration engineer in California with little or no experience?
The most realistic entry path is targeting junior integration developer or systems analyst roles at California technology companies or large health systems such as Sutter Health or Dignity Health, which run associate and new-graduate technical programs. Building hands-on experience with free-tier MuleSoft Anypoint or Dell Boomi environments and completing a vendor certification strengthens applications significantly. Adjacent roles in QA automation, ETL development, or IT business analysis at California employers also offer a lateral move into integration engineering with transferable skills.
Where can I find and apply to integration engineer jobs in California?
You can find and apply to integration engineer jobs in California on Migrate Mate, which lists current California openings from employers across the state. Find the roles that fit your experience and specialization, then apply directly through the listing.
