It is building the Polygon Open Money Stack, an open and integrated stack of services and technologies to instantly and reliably move money anywhere, and put it to work. Its infrastructure has facilitated trillions of dollars in onchain value transfer and supported millions of transactions daily for some of the globe's largest banks, fintechs, enterprises, and consumer applications.\nAI Platform Engineer\nAbout the Role\nWe are hiring an AI Platform Engineer to help build the platform that powers every agent at Polygon Labs. Polygon is a cryptocurrency company focused on on-chain payments infrastructure. As we shift to having agents manage the majority of work across engineering, business development, compliance, support, and finance, people will supervise and guide those agents while making key decisions.\nYou will join a small, flat Platform Team reporting to the AI Platform Lead. This team owns the entire AI platform, including the agent runtime, MCP servers, guardrails, evaluations, observability, and spend tracking. The team proactively identifies opportunities where AI can accelerate, improve, or automate work company-wide-including tasks that haven’t yet been automated.\nOur internal customers are Operators: domain experts in every function who manage fleets of agents and define standards of quality. This is a hands-on IC role, where you will write code, ship to production, and take ownership of your deliverables.\nYour Responsibilities\nMove agentic workflows into production, taking prototypes to robust systems for real users and owners, with SLAs (e.g. spec-to-PR agents, AI code review, incident triage, KYB review).\n\nBuild and manage MCP servers, including system design, hosting, security, authentication (e.g. per-user OAuth), and keeping a clean connector inventory for Slack, GitHub, Jira, HubSpot, and internal services.\n\nDevelop autonomous agents that act and plan across tools through trust stages: shadow, suggest, execute, and autonomous.\n\nEmbed guardrails into the platform, providing each agent its own identity, scoped credentials, audit logs, CI checks, approval gates, allowlists, and least-privilege access.\n\nBuild evaluation frameworks (test sets, regression suites, live scoring in production) so every agent releases with quality metrics tied to business outcomes.\n\nInstrument agents for observability: tracing, logging, latency, cost, drift detection, and daily dashboards for Operators.\n\nTrack AI spend across providers (Anthropic, OpenAI, OpenRouter), setting budgets, alerts, and spend attribution to teams, agents, and workflows.\n\nSupport Operators by developing features from their requests, writing documentation, running enablement sessions, and building self-service tools.\n\nCreate skills and plugins centralizing company knowledge (processes, standards, security, brand), versioning and reviewing these to ensure consistent, repeatable agent output.\n\nProactively find and automate manual, repetitive processes across the company, measuring outcomes and iterating rapidly.\n\nWhat You'll Need\n5+ years as a software, platform, or infrastructure engineer, including experience prior to AI coding tools. Solid grasp of system design, data modeling, testing, debugging, and code review.\n\n6-12 months shipping LLM-based systems to production, with agentic workflows in use by real end users.\n\nDaily, hands-on experience with AI coding agents like Claude Code and Codex to write, test, and review production code.\n\nExperience building autonomous or multi-step agents with tool use (Claude Agent SDK, Anthropic/OpenAI APIs, or similar).\n\nMCP server experience (OAuth flows, scoped tokens, user-level access control).\n\nIdentity and access experience: Okta (or similar IdP), SSO (SAML/OIDC), SCIM provisioning, group-based and device policies.\n\nCreating automated system identities (GitHub Apps, service accounts, API keys, secret managers like 1Password).\n\nDesigning guardrails: least-privilege, audit logs, CI checks, approval gates, allowlists, and policy-as-code.\n\nCreating evals for LLM systems: test sets, rubrics, CI regression, release gates, and live production scoring.\n\nInstrumenting production system observability: tracing, metrics, alerting, dashboards (OpenTelemetry, Grafana, Datadog, Langfuse, LangSmith, Braintrust).\n\nTracking AI spend across vendors: per-key limits, cost centers, budgets, actionable alerts.\n\nStrong in at least one of TypeScript, Python, Go; working knowledge of CI/CD (GitHub Actions/etc), cloud infrastructure.\n\nTrack record of independently identifying and automating manual processes (two or three concrete examples).\n\nClear, concise written communication (specs, runbooks, RFCs).\n\nPreferred Qualifications\nCryptocurrency, blockchain, payments, or fintech experience (regulated industry/audit a plus).\n\nExperience writing agent skills, plugins, or shared prompt libraries for organizational reuse.\n\nFamiliarity with model gateways (OpenRouter, LiteLLM, Portkey): key management, routing, fallback.\n\nExperience extending open-source coding agents (OpenCode, Pi).\n\nAwareness of emerging agent identity standards (MCP enterprise-managed auth, Okta Cross App Access).\n\nContext/retrieval engineering: vector stores, agent memory, permissioned retrievals.\n\nML engineering: model evaluation, fine-tuning, model routing.\n\nExperience with agent runtimes/sandboxes (Modal, n8n, containerized environments).\n\nPublic technical work: open-source tools, servers, blog posts, talks about agent production experience.\n\nHow You’ll Work\nTreat Operators as the customer-supporting engineers and non-engineers in every business function.\n\nListen to needs, refine vague asks into actionable requirements, and communicate technical concepts plainly to executives or subject matter experts.\n\nAssertively but diplomatically push back on unsafe or low-value requests, suggesting alternatives.\n\nOperate autonomously: write specs, break down projects, ship and iterate independently, and communicate progress asynchronously across time zones.\n\nUse judgment to distinguish critical automations from temporary demos, and validate changes with affected users.\n\nOwn outcomes post-merge: pilot, monitor, fix, and iterate as needed.\n\nWork transparently in public channels, tickets, written docs, and runbooks.\n\nCreate reusable assets (skills, plugins, templates, tools) from frequent learnings or solutions, making them broadly accessible across the company.\n\nSuccess in 90 Days\n30 days: Ship production changes to a live system (e.g. AI SDLC pipeline, code review, or spend analytics). Gain familiarity with agent runtime, MCP servers, spend tracking.\n\n60 days: Take end-to-end ownership of a platform area, publishing a spec and meeting with relevant Operators.\n\n90 days: Ship an agent with live-scored eval suite and Operator dashboard; complete an Operator request independently; propose and launch at least one unsolicited automation.\n\nPolygon Labs Perks\nThe goal of the Polygon Labs total rewards program is to support the health and well-being of you and your family.
