MMIC Designer

Location: Redwood City, CA | Onsite (Entry–Mid Level) / Remote Considered (Senior–Fellow Level) Employment Type: Direct Hire Compensation: $75,000 – $275,000/year (commensurate with level and experience) Travel: Minimal Start: ASAP Open Role Due To: Company growth and expansion About the Role Our client, a global leader in high-frequency RF and millimeter-wave semiconductor technology, is seeking a MMIC Design Engineer to support advanced chip design using compound semiconductor technologies. Founded by industry pioneers with decades of compound semiconductor expertise, the company is known for delivering some of the highest-linearity mmWave products available today — partnering with the world's top semiconductor foundries to do it. This is not a conventional IC design role. You will work on complex, high-performance MMIC products deployed across the most demanding applications in the industry. The team is lean, moves fast, and expects every engineer to own their work from concept through bench validation. This role focuses on designing and delivering MMIC solutions for mission-critical systems across: Satellites Aerospace and defense systems Radar and drone detection Hypersonic technologies Wireless infrastructure Instrumentation You will work hands-on across design, testing, and debugging, contributing directly to real hardware in a fast-moving environment. What You'll Do Design and develop high-performance MMICs using compound semiconductor processes Own designs end-to-end — from architecture and simulation through layout, tape‑out, and characterization Perform hands‑on bench testing, debugging, and validation of your own designs Collaborate directly with hardware, test, and leadership teams in a flat, fast‑moving environment Tackle novel technical challenges independently — reasoning from fundamentals and deriving solutions without a prescribed playbook Why This Role Stands Out Work on genuinely cutting‑edge advanced RF systems used in real‑world applications High ownership — engineers build, test, and debug their own work Strong emphasis on hands‑on execution and initiative Opportunity to grow across levels in a focused technical domain Direct visibility with company leadership, including the CEO, from day one Rare opportunity to grow within a selective, high‑impact organization Competitive compensation across a wide band, with real upside for senior and fellow‑level engineers What We're Looking For Strong MMIC design experience in high‑frequency RF / mmWave domain Experience working with compound semiconductor technologies Deep understanding of RF circuit design and chip architecture Hands‑on experience with testing, debugging, and measurement Startup or small‑team mindset — Hands‑on experience with testing, debugging, and measurement Self‑directed, curious, and comfortable operating in ambiguous, fast‑moving environments #J-18808-Ljbffr Semiconect
