Engineering Manager/Director

Job Description

Help Build the Future of Semiconductor Technology — From the Ground Up

Join a fast-growing startup that’s shaping the future of photonics and AI—right from a beautiful campus in Vancouver, Washington. At YST, innovation isn’t just a buzzword—it’s a way of life. As a key engineering leader, you'll not only help design cutting-edge laser chip testing and packaging systems—you’ll also help build the very labs they run in. From equipment installation to cleanroom expansion, you’ll work side-by-side with our facility team to scale a world-class semiconductor operation from the ground up.

About YST

YST is a high-growth startup revolutionizing the semiconductor space with next-generation DFB and EML laser chips and high-speed photodiodes. Our chips power the backbone of modern connectivity—data centers, fiber-to-the-home (FTTH), wireless networks, and AI compute engines.

We combine deep technical expertise with startup agility, and we’re looking for passionate people who are ready to build, lead, and grow with us.

What You’ll Do

As our Engineering Manager/Director of Testing & Packaging, you’ll be a hands-on leader who thrives on innovation, teamwork, and rolling up your sleeves to build something extraordinary.

In this role, you will:

Lead Testing & Packaging Operations: Oversee all aspects of laser chip testing and packaging, driving performance, yield, and reliability for cutting-edge products.

Own Equipment Strategy & Setup: Work closely with the facility team to lead equipment installation, calibration, and layout planning—including support for ongoing cleanroom expansion.

Optimize Processes: Improve throughput, automation, and efficiency across all testing and packaging stages, enabling scalable high-volume production.

Build & Lead Your Team: Hire, train, and mentor engineers—including early-career talent with no prior semiconductor experience.

Develop Future Leaders: Implement mentorship and growth pathways to develop junior engineers into industry experts.

Collaborate Cross-Functionally: Align with design, QA, manufacturing, and facilities teams to bring new products and processes to life.

Maintain Safety & Compliance: Ensure adherence to industry standards, safety protocols, and best practices.

Stay on the Cutting Edge: Monitor industry trends and emerging tech to keep YST one step ahead.

Who You Are

Experienced: 7+ years in semiconductor testing/packaging, including 3+ years with laser chips (DFB, EML).

A Proven Leader: 3+ years managing engineering teams and technical projects.

Technically Sharp: Strong hands-on experience with testing tools, wire/die bonding, optical coating, and process optimization.

Startup-Ready: Comfortable in a fast-paced, dynamic environment where you’ll wear many hats and help shape infrastructure and team culture.

A Great Collaborator: Able to work closely with both engineering and facilities teams to execute complex installations and lab upgrades.

A Mentor at Heart: Committed to teaching and developing the next generation of engineers.

Bonus If You Bring:

Experience with photonics, optical communication standards (IEEE, Telcordia), or AI infrastructure.

Familiarity with ISO 9001, JEDEC, or other semiconductor manufacturing standards.

Experience building or delivering training programs for new engineers.

Why You’ll Love YST

Inspiring Environment: Work on a serene Vancouver campus with walking paths, a cafeteria, and a gym—all steps from your desk.

Startup Energy: Make a big impact in a fast-growing company with a collaborative, hands-on culture.

Build It From Scratch: Be part of cleanroom and facility expansion, not just process development.

Tech with Purpose: Work on laser chips that are powering the next wave of global innovation.

Solid Benefits: Competitive compensation, full benefits, and endless opportunities for growth.
