Principal Software Engineer – Applied AI & Agentic Systems

Join us as our Principal AI Software Engineer and help turn Matrix42sAI Your Wayvision into secure reliable and useful product capabilities.

This is a principal-level hands-on software engineering role. You will spend most of your time designing coding testing and operating production software. You will also be a technical multiplier: working alongside developers when the problems are difficult turning working experiments into reusable components and helping product squads make sound architectural decisions.

You will connect real customer and product needs with the right combination of software data and AI. Sometimes that means a deterministic workflow; sometimes retrieval tool calling or an agentic system. Your job is to choose pragmatically prove value early and build a path from the first working vertical slice to a scalable product capability.

Your key responsibilities would be:

• Own selected AI capabilities end to endfrom problem discovery and technical design through implementation evaluation release production monitoring and continuous improvement.
• Write and review production code across AI servicesAI harnessesAPIs connectors background services MCP-compatible tools data pipelines and the product surfaces needed to deliver a complete workflow.
• Design agentic systems using the simplest architecture that works including retrieval and grounding structured outputs tool execution state and context model routing approval flows fallbacks and graceful degradation.
• Translate each use case into concrete data and platform requirements. Work with APIs event streams ingestion and transformation data quality and alignment metadata storage observability and governance so that AI results are trustworthy.
• Create results early: build focused end-to-end prototypes with small teams validate them against real workflows and evolve successful patterns into secure maintainable multi-tenant product capabilities.
• Make evaluation part of engineering. Build representative datasets automated and human-reviewed evaluations trace analysis regression gates and telemetry for quality task completion latency safety and cost.
• Engineer for enterprise trust through tenant isolation least-privilege tool access identity and authorization auditability data minimization prompt-injection defenses human approval for consequential actions feature flags and safe rollback.
• Collaborate closely with Product Design Architecture Security Support Customer Success and engineering teams. Turn customer problems into measurable outcomes unblock developers contribute reusable libraries and reference implementations and raise applied-AI engineering practices across Matrix42.

At Matrix42 you will work on AI that operates inside real service-management workflowshelping employees service agents administrators and AI leaders resolve work faster and move from reactive support toward proactive service delivery.

You will have the scope to build new AI-native capabilities while solving the harder engineering challenge: integrating them securely into a mature multi-product enterprise platform and creating a credible migration path for existing customers.

We already embrace agentic AI tools as a core part of how we build this role you will go further: shaping how we engineer evaluate secure and operate AI-powered product capabilities across Matrix42. This is technical influence through working software sound judgment and shared engineering patternsnot formal people management.

We could tell you about flexible hours and that hybrid and remote work are part of the deal. But honestly Thats just standard.

What you can expect at Matrix42 includes:

• A flexible work model that combines office and home.
• Personalized learning journeys mentorship and clear opportunities for professional growth.
• Time and support to learn experiment and improve how we build.
• A paid Social Day to give back to your community or support a cause you care about.
• Regular opportunities to connect share knowledge and build relationships across our European teams.
• A competitive location-specific benefits package.
