You will design AI agents that generate, operate, validate, monitor, and evolve backend services.\nThis role is for engineers who understand that the future of software is Human + AI co-creation, and soon - AI-to-AI collaboration.\nWhat You’ll Be Doing\nAt Unlimit, backend engineering is evolving into agent engineering.\nYou 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.\nYour 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.\nAnd 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.\nYou 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.\nThe outcome is simple but transformative: your code will not only serve production. It will serve the agents that run production.\nQualifications You Will Bring\nA 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.\nProven experience integrating LLMs, MCP servers, and multi-agent systems into real engineering workflows - not experiments, but production-oriented pipelines.\nHands-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.\n 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.\n 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.\n4+ years of strong Java (Spring/Spring Boot) or Kotlin experience in production environments - enabling you to validate, constrain, and refine what AI agents generate.\nDeep understanding of distributed systems and scalable backend architectures in high-throughput, low-latency environments.\nExperience designing resilient microservices capable of operating under financial-grade reliability and regulatory requirements.\nComfort building observable, introspectable, automation-friendly systems - because agents cannot safely operate opaque services.\n Strong communication skills to collaborate effectively in a global AI-first organization where engineering, data, compliance, and product intersect.\nNice to have:\nExperience in fintech, payments, or banking systems.\nExperience working with AWS services and infrastructure.\nFamiliarity with containerized deployments (Docker, Kubernetes) and CI/CD pipelines.\nExposure to AI-enabled systems or interest in integrating intelligence into applications.\nBackground in event-driven architectures and message-based systems (Kafka, RabbitMQ).\nWhy This Role Exists:\nSoftware developers will not disappear. But software development as we know it will.\nWe are transforming Unlimit into an AI-first, agent-native fintech platform.This role sits at the center of that transformation.\nIf you want to:\nBuild financial infrastructure for AI agents\nReplace manual engineering with autonomous systems\nDesign platforms where machines are first-class users\nWork at the frontier of fintech + AI\nThen this is your role.","description_format":"text","description_chars":4683,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Cards & Card Issuing","Financial Software & Embedded Finance","Payment Processing & Gateways","Currency Exchange & FX Payments"],"lifecycle":[{"event":"open","at":"2025-10-14T20:21:53Z"}],"visa":[],"liveness":{"score":13,"band":"cold","label":"Long shot","p_open":1,"p_active":0.467,"p_room":0.28,"age_days":366,"expected_fill_days":103,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/unlimit-agentic-systems-engineer","json_url":"https://alion.io/job/unlimit-agentic-systems-engineer.json","meta":{"generated_at":"2026-10-16T10:19:24Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":8666,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":5441},"rest":"https://alion.io/mcp/rest/get_company?id=5441"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Funlimit-agentic-systems-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Funlimit-agentic-systems-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Funlimit-agentic-systems-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/unlimit-agentic-systems-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Funlimit-agentic-systems-engineer"}]}
