Job description

Senior Technical Systems Analyst / Systems Engineer

Overview

Join a high-impact technology team developing cloud-native software platforms within a complex automotive environment. As a Senior Technical Systems Analyst / Systems Engineer, you will serve as a key technical bridge between Product Management, Software Engineering, and Project Management—transforming product vision into precise technical requirements, scalable system designs, and execution-ready delivery plans.

You will evaluate technical feasibility, author Technical Requirement Documents, define API contracts, map system dependencies, investigate integration issues, and support delivery through structured engineering processes and formal verification gates. This opportunity is ideal for a technically fluent systems professional who excels at turning ambiguity into actionable direction and guiding cross-functional teams from initial requirements through delivery.

Key Responsibilities

• Translate product requirements into detailed Technical Requirement Documents, technical specifications, and execution plans.
• Define and review API specifications and contracts using REST, GraphQL, gRPC, OpenAPI 3.0, and Swagger.
• Create sequence diagrams, document system interactions, and map cross-module software dependencies.
• Evaluate technical feasibility, identify scope gaps, and surface assumptions, edge cases, and error scenarios before development begins.
• Collaborate with Product Managers to clarify requirements and align technical direction.
• Partner with Software Engineering teams on Agile planning, backlog execution, effort estimation, and delivery scheduling.
• Investigate integration test failures and system anomalies using logs, performance traces, and observability data.
• Support root-cause analysis and resolution efforts with backend and engineering teams.
• Help align software development activities with structured engineering processes and formal verification gates.
• Organize test results, verification artifacts, and evidence packages required for evaluation and release readiness.
• Maintain clear, accurate technical documentation throughout the software development lifecycle.

Required Skills and Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Systems Engineering, or a related technical field.
• At least five years of hands-on experience as a Systems Engineer, Technical Business Analyst, Solution Architect, Technical Program Manager, or similar professional supporting cloud-native software.
• Proven ability to translate product requirements into detailed technical specifications and Technical Requirement Documents.
• Strong knowledge of API specifications and integrations, including REST, GraphQL, and gRPC.
• Experience creating or reviewing API contracts using OpenAPI 3.0 and Swagger.
• Ability to create sequence diagrams, define system interactions, and map software dependencies.
• Experience conducting technical feasibility analysis and identifying scope ambiguities, assumptions, edge cases, and error conditions.
• Hands-on experience troubleshooting integration issues using logs, performance traces, and observability platforms such as DataDog and AWS CloudWatch.
• Experience with Jira, Confluence, Postman, Swagger, Jama Software, and AWS CloudWatch.
• Strong understanding of software development lifecycles, requirements management, testing, and release readiness.
• Strong analytical, documentation, communication, and problem‑solving skills.
• Business English fluency, both written and verbal.
• Ability to collaborate effectively with Product Management, Software Engineering, Project Management, and other cross‑functional stakeholders.

Nice-to-Have Skills

• Japanese language proficiency at JLPT N2 level or equivalent.
• Experience working with automotive software platforms or connected-vehicle technologies.
• Experience with ASPICE lifecycle processes, V-Model compliance, or other high-reliability software development frameworks.
• Familiarity with ASPICE SYS.1–SYS.5 and SWE.1–SWE.6 process areas.
• Experience working within ISO 26262 or another functional safety framework.
• Experience supporting Agile sprint planning, backlog refinement, and delivery execution.
• Experience gathering engineering estimates and developing project schedules.
• Experience preparing verification artifacts, test documentation, and evidence packages for formal evaluation gates.
• Experience analyzing system performance, integration failures, and backend service behavior.
• Experience collaborating with distributed or cross‑regional engineering teams.

Preferred Education and Experience

• Bachelor’s degree in Computer Science, Software Engineering, Systems Engineering, or a related technical discipline.
• Five or more years of relevant professional experience in cloud-native software, systems engineering, technical analysis, solution architecture, or technical program delivery.
• Professional experience in automotive or another highly structured software development environment.
• Experience supporting requirements, architecture, integration, testing, and release activities across the software development lifecycle.

Other Requirements

• Work arrangement: 100% onsite in Mountain View, California.
• Schedule: Monday through Friday, 10:00 AM–7:00 PM Pacific Time.
• Engagement: Contract-to-hire with an initial six-month contract.
• Candidates must be able to work onsite five days per week during the required schedule.
• Japanese language proficiency is highly valued for cross‑regional collaboration.
• Candidates must be comfortable organizing technical information, communicating across disciplines, documenting system decisions, and maintaining accurate delivery and verification records throughout the software development lifecycle.
