Agentic Systems Engineer
"About The Role"
About This Role
Unlimit is transforming from traditional human-operated fintech into intelligent, self-evolving financial infrastructure — where APIs are consumed by machines, smart contracts and automated workflows negotiate integrations, and backend systems continuously improve through machine intelligence. As a Senior AI Agent Engineer with strong Java/Kotlin expertise, you'll architect the agentic backend layer powering a platform spanning payment processing, multi-currency accounts, BaaS, and crypto gateways across 17 global offices. This isn't incremental engineering — it's building the nervous system for a new era of distributed, autonomous finance.
What You'll Be Doing
Design and build AI agents capable of generating, deploying, and validating backend services autonomously
Architect robust Java/Kotlin systems that integrate seamlessly with blockchain-based payment rails and crypto gateways
Develop monitoring and self-healing mechanisms that allow agentic systems to detect anomalies and evolve without constant human oversight
Collaborate with cross-functional teams to embed decentralized finance (DeFi) principles into core infrastructure
Build frameworks enabling AI-to-AI negotiation and integration across distributed ledger-powered financial services
Continuously refine agent behavior models to improve reliability, scalability, and security across the platform
What We're Looking For
Deep, hands-on expertise in Java and Kotlin for building high-performance backend systems
Proven experience designing distributed systems, ideally within fintech, blockchain, or web3 environments
Strong understanding of API architecture, microservices, and automated integration patterns
Familiarity with smart contracts, crypto payment infrastructure, or decentralized protocols
Comfort working at the intersection of AI/ML systems and traditional software engineering
A mindset oriented toward experimentation, autonomy, and building systems that "think" and adapt
Bonus Points
Experience designing or deploying AI agents in production environments
Background contributing to open-source blockchain or DeFi projects
Knowledge of multi-agent orchestration frameworks
Exposure to BaaS platforms or cross-border payment systems
Why Join Us
Competitive compensation with performance-based growth opportunities
Work alongside a globally distributed team shaping the future of AI-native finance
Direct influence over infrastructure powering a borderless, decentralized economy
Access to cutting-edge tools, autonomy, and continuous learning in blockchain and AI innovation
Requirements
What You’ll Be Doing At Unlimit, backend engineering is evolving into agent engineering. You won’t simply write Java or Kotlin services. You will design and implement AI agents that build, refactor, test, and optimize those services — agents that actively participate in the software lifecycle rather than passively assisting it. Instead of creating microservices only for human consumption, you will architect systems that are self-describing, agent-consumable, and machine-operable by design. Your APIs will not just be called — they will be reasoned about. AI systems will understand their contracts, constraints, and behaviors. You will help construct a full pipeline from requirements to deployment, where validation agents automatically enforce PCI-DSS rules, regulatory constraints, scalability requirements, and architectural standards. Compliance will not be a checklist at the end — it will be continuously verified by intelligent systems embedded in the flow. And it won’t stop at build-time automation. You will develop autonomous monitoring agents capable of detecting anomalies, diagnosing root causes, and triggering corrective workflows in production environments operating at global financial scale. Traditional microservices will be redesigned into agent-ready execution units — modular, observable, introspectable components that machines can safely evolve. You will collaborate closely with DevOps, Data, and AI teams who are building their own agents, uniting these systems into a coordinated multi-agent ecosystem that powers our financial infrastructure. The outcome is simple but transformative: your code will not only serve production. It will serve the agents that run production. Qualifications You Will Bring A mindset that sees AI not as a tool, but as a new execution layer. You design systems where agents act, validate, and evolve software — not just assist humans. Proven experience integrating LLMs, MCP servers, and multi-agent systems into real engineering workflows — not experiments, but production-oriented pipelines. Hands-on work with frontier models such as Claude Opus 4.x, GPT-5.x Codex or similar — using them for structured reasoning, code generation, validation, orchestration, and system design. Strong understanding of context engineering and token economics — including prompt architecture, reusable memory patterns, retrieval layers (RAG), persistent state management, and optimizing token consumption for long-horizon agent workflows. Ability to design guardrails for autonomous systems — validation layers, policy enforcement, compliance checks, circuit breakers, and architectural constraints that keep AI-driven systems stable and safe. 4+ years of strong Java (Spring/Spring Boot) or Kotlin experience in production environments — enabling you to validate, constrain, and refine what AI agents generate. Deep understanding of distributed systems and scalable backend architectures in high-throughput, low-latency environments. Experience designing resilient microservices capable of operating under financial-grade reliability and regulatory requirements. Comfort building observable, introspectable, automation-friendly systems — because agents cannot safely operate opaque services. Strong communication skills to collaborate effectively in a global AI-first organization where engineering, data, compliance, and product intersect. Nice to have: Experience in fintech, payments, or banking systems. Experience working with AWS services and infrastructure. Familiarity with containerized deployments (Docker, Kubernetes) and CI/CD pipelines. Exposure to AI-enabled systems or interest in integrating intelligence into applications. Background in event-driven architectures and message-based systems (Kafka, RabbitMQ). Why This Role Exists: Software developers will not disappear. But software development as we know it will. We are transforming Unlimit into an AI-first, agent-native fintech platform.This role sits at the center of that transformation. If you want to: Build financial infrastructure for AI agents Replace manual engineering with autonomous systems Design platforms where machines are first-class users Work at the frontier of fintech + AI Then this is your role.
