Join us for exciting professional challenges, working on projects ranging from innovative startups to globally recognized brands. Our positions are full-time, remote, and offer competitive compensation in USD.\nWe are seeking a Senior Backend Engineer to join a team building a shared AI agent platform. The platform provides the contracts, identity and access controls, runtime capabilities, and evaluation and release workflows that other teams use to build and operate agents.\nThe broader roadmap includes Slack and voice integrations, data ingestion, file exchange, multi-agent orchestration, scheduled and event-driven execution, dynamic skill loading, and controls for handling sensitive data.\nYou will own a technical area end to end: design and implement it, align directly with SRE, DevOps, and security teams, and document it so other engineers can build on your work.\nResponsibilities:\nDesign and evolve versioned agent contracts and validators, including permissions, approval modes, and mappings between agent capabilities and infrastructure access.\n\nBuild reliable APIs and streaming interfaces for agent invocation, discovery, and interoperability, including JSON-RPC, server-sent events, and protocols such as A2A.\n\nImplement secure authentication and authorization flows, including token verification, audience validation, token exchange, and identity propagation to downstream tools.\n\nBuild automated evaluations and release gates for non-deterministic systems, covering expected behavior, required refusals, and meaningful regressions.\n\nExpand reusable platform capabilities across integrations, agent workflows, data ingestion, file exchange, orchestration, and scheduled or event-driven execution.\n\nHarden the runtime with restrictive tool policies, resource and cost limits, timeouts, reliable health checks, and graceful shutdown.\n\nContribute to secure CI/CD workflows and infrastructure across AWS, Kubernetes, and Terraform.\n\nImplement sensitive-data controls in collaboration with security and infrastructure teams.\n\nHelp other teams adopt the platform through clear interfaces, documentation, examples, and reusable development workflows.\n\nWrite technical specifications and architecture decision records, making scope, trade-offs, and operational expectations explicit.\n\nRequirements:\n5+ years of Backend Engineering experience.\n\nStrong Python skills, including asynchronous execution, concurrency, debugging, and reliability under load.\n\nExperience designing APIs and working with streaming or asynchronous communication.\n\nUse of AI-assisted development tools such as Claude Code, Cursor, or equivalent, including reviewing, testing, and debugging generated code.\n\nExperience automating repetitive engineering work to improve development speed and reliability.\n\nExperience integrating LLMs into production systems, including agents that call tools.\n\nFamiliarity with agent frameworks or protocols such as LangChain, LangGraph, MCP, or A2A.\n\nExperience evaluating LLM-based systems through automated tests, evaluation datasets, or other systematic quality checks.\n\nPractical understanding of OAuth 2.0, OIDC, token verification, and authorization.\n\nHands-on experience with cloud infrastructure and containerized services, preferably AWS and Kubernetes.\n\nStrong English communication skills - Minimum B2 level proficiency.\n\nSend your application and CV in English (mandatory).\n\nBased in Latin America.\n\nBenefits:\nRemote work\n\nFlexible schedule\n\nCollaboration with international clients\n\nUSD compensation\n\nPaid Holidays and Vacations\n\nPaid family and sick leaves\n\nEnglish classes\n\nEducational and wellness bonus\n\nStructured career plan with regular salary reviews\n\nEmphasis on personal growth and mentorship\n\nAre you ready to be part of the ioet journey?\nGet your CV in English and Apply Now.\nIf you are curious to know more about our culture, technologies, and blogs, visit
