Senior Model Jobs in Berkeley, CA (NOW HIRING)

We are looking for a Senior Model-Based Systems Engineer – Integration, Verification & Validation (IV&V) to own interface management and the full system verification and validation program across Rondo’s products. This role is responsible for planning, defining, and reporting on all integration and V&V activities, from requirements through final evidence packages. 

What You’ll Do 

Interface Management 

• Own all interface boundary definitions and configuration control; author and maintain Interface Control Documents (ICDs), delegating responsibility to subsystem leads where appropriate to ensure 100% interface coverage and oversight. 

• Use interface analysis methods — context diagrams, N2 diagrams, functional analysis, FMEA/STPA, etc. — to identify interactions, assess risks, and define requirements; maintain bidirectional traceability to the system architecture and V&V artifacts. 

• Plan and define interface verification activities; coordinate cross-functional review and approval of interface changes; ensure every change triggers an impact assessment. 

• Verify that discipline engineers are performing clash detection, envelope compliance, and tolerance stack-up checks correctly in a federated CAD/PLM model. 

V&V Planning and Definition 

• For every requirement, define the V&V success criteria, strategy, and method across a combination of model-based simulation and physical testing. 

• Develop V&V plans for system, subsystems, and system elements; author procedures; schedule verification events and enforce a logical bottom-up integration sequence. 

• Work in close collaboration with subsystem and functional to confirm plans are comprehensive. 

• Collect evidence from execution teams, review for correctness and completeness, manage discrepancies and noncompliance through to closure, and assemble the final compliance summary. 

• Plan and define V&V for all phases of on-site commissioning. 

Toolchain Integration and Workflow Automation 

• Build and maintain automated workflows in an AI-powered systems engineering platform to connect requirements, interfaces, simulations, verification status, interface changes, and traceability into a live, continuously updated picture of program health. 

• Author AI skills to automate repetitive SE tasks: requirements quality checks, coverage gap detection, interface impact analysis, and verification status roll-ups. 

Reporting and Compliance 

• Maintain end-to-end bidirectional traceability from stakeholder needs through requirements, interfaces, risks, and verification evidence. 

• Present verification readiness and evidence status at program reviews; produce compliance summaries and requests for variance or concessions where needed. 

• Ensure functional safety (IEC 61511), cybersecurity (IEC 62443), and other regulatory requirements are fully evidenced; apply risk-based prioritization. 

What You Bring 

• 7+ years in systems, integration, or verification engineering on complex multi-disciplinary, software-intensive systems (energy storage, industrial, aerospace, automotive, robotics, or similar); 3+ years in a model-based engineering environment. 

• Hands-on interface management experience. 

• Demonstrated experience writing system-level V&V plans and defining verification strategies in a model-based simulation environment. 

• Experience with requirements management tools (Jama, Flow) and bidirectional traceability. 

• Comfortable with SolidWorks or equivalent PLM/CAD environments. 

• Familiarity with CFD and reduced-order modeling tools (Ansys, MATLAB/Simulink) sufficient to define and validate toolchain integrations. 

• Comfort working with AI-powered tools and building automation workflows; hands-on experience with Claude and MCP server development is a strong asset. 

• Working knowledge of SysML and at least one MBSE tool (Catia Magic/Cameo, Rhapsody, Capella); experience defining V&V attributes and traceability inside the model. 

• Familiarity with safety and risk analysis methods (FMEA, FTA, STPA) and their connection to verification planning. 

• Familiarity with top-down SE processes (ISO 15288, INCOSE) and MBSE methods. 

• Strong communication, able to teach, influence, and lead across functional design teams. 

Bonus Points 

• Experience with model-based product line engineering and/or product variant management. 

• Familiarity with digital twins, model correlation, or early-stage virtual verification. 

• On-site commissioning experience, ideally on first-of-a-kind (FOAK) or early-commercial systems in energy storage, industrial, or infrastructure sectors. 

• Acceptance testing experience (FAT, SAT, or equivalent). 

• INCOSE ASEP or CSEP certification. 

What We Offer:

• Comprehensive Medical Benefits
• Dental & Vision Benefits
• Life Insurance and ADD
• Up to 13 paid holidays per year, in addition to a company week-long holiday in December
• Flexible time off policy
• Catered lunches on-site
• 401(k) plan with company match
• Rondo HQ is close to Oakland airport - one block from the Bay - and has stunning Bay views!

This role necessitates being on-site at our Alameda HQ several times per week.
