Agentic Systems Engineer
"About The Role"
About This Role
Unlimit is a global fintech ecosystem dismantling the financial borders that hold businesses back — fusing payment processing, multi-currency accounts, BaaS, and crypto gateways into one intelligent platform. With 17 offices worldwide, we're transforming from human-operated fintech into a distributed, AI-driven system where smart contracts, autonomous agents, and machine-to-machine integrations power a decentralized global economy. This is a rare opportunity to work at the intersection of blockchain, web3, and agentic AI — shaping infrastructure for a future where our users aren't only humans, but AI agents acting on their behalf.
What You'll Be Doing
Design and build the agentic backend layer that powers Unlimit's distributed financial platform, using deep Java/Kotlin expertise
Architect AI agents capable of generating, operating, validating, and monitoring backend services autonomously
Build systems that evolve continuously through intelligent automation rather than static deployment cycles
Collaborate across teams to integrate crypto gateways, smart contracts, and decentralized payment rails into agent-driven workflows
Establish frameworks for Human + AI co-creation, paving the way toward AI-to-AI collaboration
Monitor and refine agent-generated code to ensure reliability across a high-capacity financial network
What We're Looking For
Senior-level Java/Kotlin engineering experience with strong backend architecture skills
Proven track record designing scalable, distributed systems in fintech, blockchain, or web3 environments
Familiarity with crypto infrastructure, decentralized platforms, or DeFi protocols
Strong understanding of AI/LLM-driven development workflows and agentic design patterns
Excellent problem-solving skills and comfort operating in ambiguous, rapidly evolving technical territory
Strong communication skills to collaborate across global, cross-functional teams
Bonus Points
Experience building or integrating smart contracts
Exposure to agent orchestration frameworks or autonomous AI systems
Background in payment processing or BaaS infrastructure
Contributions to open-source blockchain or AI tooling projects
Why Join Us
Competitive compensation with growth potential tied to a rapidly scaling fintech ecosystem
Flexible, high-trust work culture across a globally distributed team
Direct impact on the infrastructure powering the next generation of decentralized finance
Unmatched learning opportunities at the frontier of AI-native systems and web3 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.
