Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Staff-level engineer - **Company:** Kirshenbaum Bond Senecal & Partners LLC - **Location:** San Francisco, CA, United States - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Computer-Aided Design, Abaqus, SolidWorks (CAD), Hardware Design, Python (Programming Language), MATLAB, Reliability Engineering - **Published:** September 23, 2026 - **Apply:** https://startup.jobs/staff-cae-engineer-li-me-10157353 ## About the Role * Education: MSc in Mechanical Engineering (or a related engineering discipline), or equivalent practical experience. * Experience: 10+ years of CAE simulation and mechanical design experience on commercialized products. Proven portfolio in advanced structural optimization, non-linear analysis, and mechanism design. * Engineering Fundamentals: Deep, first-principles understanding of solid mechanics, materials, elasticity, plasticity, fatigue, and weldment/fracture mechanics. * Advanced CAE Expertise: Mastery of Multibody Dynamics (MBD), explicit vs. implicit solvers, non-linear transient mechanics, and random vibration (NVH) analysis. * Software Toolkit: Advanced proficiency in Abaqus (highly preferred), SIMULIA suites (Fe-Safe, Tosca, iSight), or equivalent high-end solvers, alongside 3D CAD software (SolidWorks preferred). * Simulation Automation: Proven ability to build simulation automation workflows for efficient model processing using Python or MATLAB. * Pragmatic Mindset: Highly autonomous problem solver who knows how to translate raw simulation data into actionable design directives and knows when to simulate versus when to physically prototype. * Material Expertise: Aluminum metallurgy (6000 series), advanced manufacturing (HPDC casting, forging, extrusion), heat treatment (T4/T6), fatigue & fracture mechanics (S-N Curves, crack propagation), and weldment analysis. Preferred Experience: * Prior engineering experience within the automotive, bicycle, or adjacent micro-mobility industries. ## Description Lime is looking for a Staff CAE Engineer to lead the structural integrity, safety, and weight optimization of our next-generation shared micro-mobility vehicles and infrastructure. In this role, you will act as a technical authority autonomously identifying, scoping, and solving the thorniest hardware challenges across our global vehicle platforms. As a Staff-level engineer you work in conjunction with the mechanical engineering team to provide timely results in alignment with our Product Development Process. By delivering high-fidelity simulation data before design freezes, you will prevent engineering bottlenecks and eliminate late-stage development risks. You bring the pragmatic judgment required to balance digital engineering with physical realities, confidently determining when a problem warrants complex simulation versus when it is faster and cheaper to just build and test. This is a hybrid role requiring 2 days per week in our San Francisco Hardware Development Lab for collaboration, prototyping, and testing. Interview Note: We love to see engineering portfolios. Be prepared to walk us through a case study showing a complex structural failure or optimization challenge, your model correlation methodology, and the final design solution you delivered. What You'll Do: * Locking Mechanism & Overload Analysis: Own the advanced simulation of our complex electro-mechanical locking ecosystem (including battery, hub, helmet, lock-to, and docking modules). Utilize Multibody Dynamics (MBD) and non-linear transient analysis to ensure these assets withstand extreme real-world impact and intentional vandalism before committing to production tooling. * Structural Weight Optimization: Drive the optimization of vehicle frames and weldments early in the design cycle. Use precise fatigue and weldment simulations to safely strip away conservative margins, lowering per-unit manufacturing costs and vehicle weight before designs are locked for tooling. * Dynamic & Environmental Simulation: Lead high-fidelity explicit dynamics simulations for severe, short-duration impact events (drops, sidefalls, curb strikes) alongside random vibration analysis to replicate aggressive road testing virtually. * Test & Field Correlation: Partner closely with the Reliability engineering team to correlate analytical CAE models with lab tests and actual field failure data, continuously elevating Lime's predictive engineering capabilities. * Global Collaboration & Manufacturing Support: Partner cross-functionally with internal engineering units and external suppliers globally. Support vehicle builds directly at our Asian Contract Manufacturers (CMs), which includes international travel approximately 2-3 times per year. ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Quantum Computing - The tiny and the big challenges](https://www.wearedevelopers.com/videos/934-quantum-computing-the-tiny-and-the-big-challenges) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [The future of automotive mobility: Upcoming E/E architectures, V2X and its challenges](https://www.wearedevelopers.com/videos/374-the-future-of-automotive-mobility-upcoming-e-e-architectures-v2x-and-its-challenges) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) ## Related Articles - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [What Jobs Can You Get with a Software Engineering Degree?](https://www.wearedevelopers.com/magazine/398-what-jobs-can-you-get-with-a-software-engineering-degree)
