Descripción del empleo

Obsidiam is hiring a Lead Software Architect to own the technical foundation of a regulated cross-border payments platform serving Latin America — serious money movement, built to a regulated standard, in a fast-growing market.

You'll turn an ambitious product vision into a concrete architecture, decide what we build versus integrate, and shape the engineering team around it.

WHAT YOU'LL DO

• Translate our product and business vision into a clear technical blueprint.
• Design the overall system architecture for a secure, regulated, multi-jurisdiction payments platform.
• Own the build-vs-buy and technology decisions across the stack — custody/wallet infrastructure, liquidity, banking and local payment rails, FX, the API layer, and reconciliation.
• Architect for compliance and security from day one — AML and the controls a regulated payments business requires.
• Define the team we need: estimate headcount and the specialties required (backend, frontend, DevOps/SRE, security, data engineering, AI).
• Build the development roadmap and milestones; set engineering standards and CI/CD.
• Identify and mitigate technical and security risks — key management, transaction integrity, custody — before significant capital is committed.

WHAT WE'RE LOOKING FOR

• Senior/principal-level experience as a software architect or staff+ engineer, ideally including a from-scratch (0→1) build.
• Deep, hands-on expertise in AI, machine learning, and operations research and optimization (OR) systems — this is central to the role, not peripheral.
• Strong background in payments, fintech, or digital-asset infrastructure, including stablecoin, treasury, or cross-border FX.
• Deep distributed-systems and API-design expertise; event-driven, cloud-native architectures (Kubernetes, GitOps).
• Security-first mindset and experience designing for regulated environments.
• Hands-on with one or more of: wallet/custody infrastructure, liquidity/trading integrations, banking-as-a-service or local payment rails.
• Excellent English; Spanish and/or Portuguese a plus.

LOCATION & SETUP

We're based in San José, Costa Rica — and we're deliberately hiring beyond it.

• The first month is on-site in San José with the founding team: full immersion in the product and the architecture. We support travel and accommodation.
• After that, the role is primarily remote — but not guaranteed fully remote. You should be ready to spend time in Costa Rica on a recurring basis and to travel frequently whenever the project calls for it.
• We need genuine commitment to being on the ground when it matters, with working-hours overlap across the Americas.
• Open to candidates across Latin America and internationally who can commit to that.
