Senior Elixir Developer

About the role

Agentic Contracts are legally binding agreements that automate financial flows, structure compliance, and capture verifiable evidence directly from the contract itself. Our platform is used by enterprises, law firms, and financial institutions in regulated markets such as alternative investments, corporate debt, maritime finance, and eGovernment.

Responsibilities

• Designing and building OTP-based services that orchestrate contract execution, scheduled obligations, and counterparty workflows
• Integrating with open banking APIs, sanctions/KYC providers, and external data feeds (interest rates, IoT telemetry, asset registries)
• Building robust event sourcing and audit trails that meet regulatory-grade evidence standards
• Phoenix / LiveView interfaces for contract authoring, monitoring, and human-in-the-loop sign-off steps
• Collaborating with our legal, compliance, and product teams to translate clauses into reliable executable behavior
• Contributing to architectural decisions around messaging, persistence, and integration with our Web3 layer (Stellar / Hyperledger)

Requirements

• 4+ years of professional backend experience, with at least 2 years writing production Elixir
• A strong grasp of OTP, including supervisors, GenServers, process design, and fault tolerance
• Solid experience with Phoenix and Ecto, PostgreSQL, and designing well-bounded service APIs (REST and/or GraphQL)
• Comfortable with testing discipline (ExUnit, property-based testing welcome)
• Fluent English (our team and customers are international)

Qualifications

• Nice to have: LiveView in production, background in fintech, legaltech, regulated industries, or anywhere correctness and auditability matter, experience with event sourcing, CQRS, or distributed systems patterns, exposure to Web3 / smart contract platforms (Stellar, Hyperledger, or similar), Erlang, Rust NIFs or other BEAM-adjacent skills
