Software Architect — Government AI Platform

Software Architect — Government AI Platform

Location: Remote (Europe)
Type: Full-time • Stock Options Included

Our client is a next-generation Government Tech & AI startup on a mission to bring transparency and accountability to global public procurement systems.

Founded in 2024 and headquartered in Lisbon (soon to be incorporated in Dubai), the company is building AI-powered procurement transparency solutions for governments worldwide — think Palantir, but built for multiple governments and open ecosystems rather than for a single national structure.

Their vision: to replace opaque, corruption-prone government procurement with data-driven, AI-enabled transparency that any government can adopt.

The Role

We’re looking for a Software Architect to lead the complete rebuild and modernization of the company’s AI-driven government procurement platform.

You’ll take ownership of the system’s architecture — designing and implementing a secure, enterprise-grade foundation to replace the current MVP, which requires a full re-engineering effort.

This is a strategic and hands-on technical leadership role, responsible for transforming a startup product into a scalable, production-ready platform capable of serving governments and large enterprises globally.

Key Responsibilities

  • Lead the complete architectural redesign of the current MVP into a scalable, secure enterprise-grade platform

  • Design AI agent orchestration architecture integrating multiple LLMs (GPT-4, Grok, Anthropic, Gemini, OpenAI, etc.)

  • Define and enforce enterprise-level security and compliance standards for government integrations

  • Optimize database architecture for large-scale procurement data (currently using Neo4j)

  • Collaborate closely with leadership on technical vision, scalability, and roadmap planning

  • Build and mentor a technical team as the platform scales internationally

  • Report directly to the company’s leadership team

Technical Requirements

  • Senior-level experience in software architecture for complex, enterprise-grade systems

  • Strong background in AI/ML infrastructure and multi-LLM system integration

  • Proven expertise in database design and optimization (preferably graph or hybrid systems like Neo4j)

  • Experience with enterprise security, government compliance, or regulated environments

  • Demonstrated success in rebuilding large-scale or legacy systems from scratch

  • Experience in technical leadership and team building within a startup or fast-scaling environment

What We Offer

  • A strategic technical leadership role with hands-on implementation ownership

  • Above-market compensation and a high-upside equity package

  • Freedom to shape the technical stack and architecture according to your expertise

  • Fully remote role within Europe, with flexibility and autonomy

  • Opportunity to make a global impact on government transparency and accountability
