Job Description
Package Mechanical Design Engineer
Cisco
• Perform advanced finite element analysis (FEA) to evaluate thermomechanical reliability of ASIC packages and board-level assemblies • Lead solder joint reliability simulations, including thermal cycling, mechanical shock, and vibration • Develop lifetime prediction models based on industry methodologies (e.g., Coffin-Manson, Darveaux) • Model and analyze time-dependent material behavior, including creep, viscoplasticity, and fatigue • Drive board-level reliability (BLR) assessments, including PCB–package interactions and SMT effects • Correlate simulation results with reliability testing data to improve model accuracy • Develop and automate simulation workflows using Python, Fortran, or similar tools • Provide design recommendations and reliability sign-off guidance to cross-functional teams • Document methodologies, assumptions, and results clearly to support engineering reviews
Job Requirements
- Bachelors + 7 years, or Masters + 4 years, or PhD + 1+ years in mechanical engineering or related field
- Hands-on experience in thermomechanical simulation of semiconductor packages and board-level assemblies
- Proven experience in solder joint reliability analysis, including fatigue and/or creep modeling
- Strong experience with FEA tools such as ABAQUS or ANSYS, including nonlinear material modeling
- Familiarity with CAD tools (e.g., Creo) and GD&T
- Ability to collaborate across global teams.

• Lead mechanical engineering work for nuclear facility, power, or complex industrial projects. • Develop and review calculations, drawings, specifications, reports, and technical design documents. • Support design of piping systems, mechanical equipment, thermal systems, and related plant components. • Perform or review engineering analysis involving stress, pressure, heat transfer, flow, equipment loads, and system performance. • Coordinate with civil, structural, electrical, I&C, project management, procurement, and construction teams. • Ensure designs meet applicable codes, standards, client requirements, and project specifications. • Provide technical guidance to junior engineers and designers. • Support design reviews, client meetings, field questions, RFIs, submittals, and engineering change activities. • Identify technical risks, resolve design issues, and maintain quality across engineering deliverables.
• Own the design of our API and integrations areas end to end — from developer-facing API surfaces and documentation experiences to the in-product flows users rely on to connect their tools; • Partner with product and research to shape strategy for these surfaces — staying close to how the market and the audience are shifting as the barrier to working with APIs and MCP falls, and translating that into how we design for a broader, evolving set of users; • Design and prototype AI-native patterns for our API — including our ChatGPT app, Claude connector, and MCP integration — surfaces where PandaDoc meets AI assistants and agentic workflows; • Shape how integrations feel across the product, with intent around two questions in particular: how our core CRM integrations (Salesforce, HubSpot) need to adapt for an agentic world, and how we balance the integrations we build ourselves against the connections customers orchestrate for themselves in surfaces like Claude via MCP — when each makes sense, when a hybrid is right, and how to design an experience that intentionally guides customers to the best option for them; • Prototype ideas in code, fast. Take a concept from Figma or an LLM conversation to a working production-grade React component in days, owning layout, interaction, accessibility, and performance; • Trailblaze the Design Engineer function at PandaDoc. Own work end to end, from problem framing to launch, and shape how this role operates as the first hire in it; • As the only Design Engineer on the Embedded Agreements team, bring your technical perspective into the design process — sharing patterns, pairing on prototypes, and helping the designers around you improve their technical skills over time; • Work AI-first in Cursor and Claude Code, and bring strong opinions on how to get high-quality output from these tools.
