Senior IC Packaging Engineer

Key Responsibilities

• Serve as technical authority for IC and SiP packaging across multiple products and programs.
• Own package architecture and technology roadmap, aligned with product, cost, and scalability goals.
• Lead chiplet-based packaging strategies, including UCIe, silicon interposers, and advanced RDL.
• Perform and guide hands-on package design and physical layout, including critical structures for High-speed SerDes/PHY (PCIe, CXL), LPDDR5, UCIe, and Other multi-gigabit interfaces.
• Define substrate stack-ups, materials, bump/RDL architectures, and DFM guidelines for advanced nodes.
• Drive SI/PI, thermal, mechanical, and reliability trade-offs at the system and package levels.
• Lead external engagement with OSATs, foundries, and key suppliers for technology development and manufacturing readiness.
• Influence product roadmap, risk management, and investment decisions through technical insight.
• Establish scalable design methodologies, best practices, and reusable packaging flows.

Required Experience

• Technical leadership of multiple end-to-end packaging programs, from early architecture through high-volume production.
• Proven experience with high-speed SerDes package development, including PCIe Gen5, LPDDR5 / LPDDR5X, USB 3.x or 10G interfaces
• Experience defining die-to-die and chiplet based RDL/bump architecture.
• Direct collaboration with OSATs, foundries, and substrate suppliers for co-development and ramp.
• Strong cross-functional leadership across design, product, test, operations, reliability, and customer teams.
• Clear understanding of cost, yield, schedule, and risk trade-offs at a product and portfolio level.
• Tools & Preferred Skills
• Cadence Allegro Package Designer (APD) or equivalent EDA tools.
• Strong background in flip-chip BGA package design and layout.
• SI/PI expertise preferred, including S-parameter extraction and PDN optimization using HFSS, SIwave, or Ansys Designer.
• Experience building new packaging methodologies or platforms from scratch.
• Axiado is committed to attracting, developing, and retaining the highest caliber talent in a diverse and multifaceted environment. We are headquartered in the heart of Silicon Valley, with access to the world's leading research, technology and talent.
• We are building an exceptional team to secure every node on the internet. For us, solving real-world problems takes precedence over purely theoretical problems. As a result, we prefer individuals with persistence, intelligence and high curiosity over pedigree alone. Working hard and smart, continuous learning and mutual support are all part of who we are.
