Job description

Overview

Lattice is a worldwide community of engineers, designers, and manufacturing operations specialists in partnership with world‑class sales, marketing, and support teams. We are developing programmable logic solutions that are changing the industry. Our focus is on R&D, product innovation, and customer service, and we bring total commitment and a keenly sharp competitive personality. Energy feeds on energy. If you flourish in a fast‑paced, results‑oriented environment and can contribute to a demanding yet collegial atmosphere, Lattice may be just what you’re looking for.

Job Responsibilities

As a technical leader, provide applications support for DDR (e.g., DDR4 / DDR5 / LPDDR, High‑Speed IOs, interfaces such as PCIe, SerDes, Ethernet). Support customer design‑ins, including interface configuration, signal integrity guidance, board‑level considerations, and system optimization. Analyze issues using oscilloscopes, logic analyzers, protocol analyzers, and BERTs; provide clear root‑cause and corrective action plans. Provide customer feedback to internal teams to influence product requirements, feature prioritization, and roadmap decisions. Support FAE, sales, and marketing teams with technical guidance, value propositions, and contribute to best practices for DDR and HSIO system design and debug. Stay current on JEDEC standards, protocol specifications, and industry trends related to memory and high‑speed interfaces.

Required Skills

• Solid understanding of DDR memory architectures and protocols (DDR4/DDR5 and/or LPDDR).
• Hands‑on experience supporting silicon products (SoCs, PHYs, controllers, memory interfaces).
• Strong knowledge of High Speed Serial and Parallel IO fundamentals, including signal integrity, timing, jitter, noise, power integrity, eye diagrams, timing budgets, and channel modeling.
• Experience with high‑speed lab equipment (oscilloscopes, protocol analyzers, BERTs).
• Familiarity with PCB design considerations for high‑speed interfaces (stack‑ups, routing, termination).
• Ability to explain complex technical topics clearly to both technical and non‑technical audiences.
• Strong problem‑solving and analytical mindset.
• Familiarity with memory training, calibration flows, and PHY tuning.

Compensation & Benefits

In addition to base pay, this role may be eligible for variable/incentive compensation and/or equity. The position also offers a comprehensive, competitive benefits package which may include healthcare and retirement plans, paid time off, and more.
