Job description

About u-blox u-blox is a global leader in automotive, industrial, and consumer markets, driving innovation through our cutting-edge positioning and short-range communication technologies. We are the pioneers behind high-precision technologies, providing smart and reliable solutions that enable people, vehicles, and machines to determine their precise position and communicate wirelessly. With headquarters in Thalwil, Switzerland, and offices across Europe, Asia, and the USA, we are making a global impact.

Job Description

As a System Architect, you play a leading technical role in the development of advanced positioning solutions. Leveraging your deep expertise in GNSS technologies, you derive system architectures and technical solution concepts from stakeholder and product requirements.

You define system structures, interfaces, requirements, and technical concepts across disciplines and collaborate with component architects to ensure a coherent overall system architecture. You facilitate architectural decisions, evaluate technical trade-offs, and ensure alignment between business objectives, customer requirements, and implementation constraints.

Throughout development, integration, and verification, you provide technical guidance and ensure consistency between requirements, architecture, and delivered functionality.

You ensure that system-level architecture concepts are grounded in GNSS application needs and positioning use cases, so that hardware, software, and platform decisions deliver clear product value.

As the System Architect with focus on APNT and defense, you own the end-to-end architecture and technology roadmap for resilient positioning solutions spanning GNSS receivers, sensor fusion, antenna and CRPA technologies, anti-jamming, anti-spoofing, and APNT capabilities for defense and mission-critical applications.

Acting as the technical authority for positioning resilience, you translate customer needs, operational use cases, market developments, and competitive insights into differentiated platform capabilities that enhance robustness, integrity, and PNT performance in contested, degraded, and GNSS-denied environments. You work closely with product teams, product strategists, and engineering organizations to define future platform requirements, drive resilience strategies, and guide technology development activities.

This position reports to the director of platform system architecture.

Your Responsibilities:

• Derive system requirements from stakeholder and product requirements
• Lead and contribute to the creation, evaluation, and maintenance of technical solution concepts and system architectures.
• Define system‑level requirements, interfaces, and performance budgets
• Conduct trade‑off analyses and technical feasibility assessments
• Align architectural decisions with stakeholders and development teams
• Guide component architects and ensure architectural consistency across subsystems
• Support implementation, integration, verification, and validation activities
• Identify technical risks and propose mitigation strategies
• Maintain architecture documentation

Additional responsibilities for role focus:

• Define platform‑level resilience requirements covering anti‑jamming, anti‑spoofing, signal authentication, APNT, sensor fusion, and interference mitigation technologies
• Drive resilience strategy and guide product and technology development teams in resilience‑related architectural decisions
• Define and evaluate technical concepts for operation in contested, degraded, and GNSS‑denied environments
• Translate customer needs, operational use cases, market trends, and competitive insights into platform capabilities and product requirements
• Act as the primary technical interface for resilience‑related topics towards internal product teams, product strategists, and key customers
• Evaluate emerging technologies in GNSS resilience, APNT, CRPA, sensor fusion, and navigation warfare applications

Secondary Responsibilities:

• Contribute to long‑term resilience and APNT technology roadmaps
• Monitor market trends, defense requirements, and competitive developments related to resilient PNT
