The posting

Responsibilities

  • Agent platform and orchestrationBuild and improve agent harnesses, including model and tool execution loops, context management, and structured outputs. Implement multi-step workflows with clear execution boundaries, task state, asynchronous dispatch, and human approval where needed.
  • Enterprise systems and integrationsDevelop reusable tools and connectors for enterprise APIs, webhooks, and services, with clear input and output contracts. Handle data mapping, user authorization, rate limits, and integration errors; document dependencies with system owners.
  • Full-stack product deliveryDesign Python backend services, secure REST APIs, and PostgreSQL data models for agent and workflow features. Build responsive web interfaces for task progress, user confirmations, and results using TypeScript and modern frontend frameworks.
  • Security and reliabilityProtect credentials, preserve user access boundaries across systems, and apply appropriate execution isolation and audit logging. Improve concurrency control, retries, idempotency, cancellation, and recovery; trace failures across model calls, tools, and workers.
  • Quality and collaborationMaintain automated and integration tests, CI/CD, and agent evaluations covering task success, output quality, latency, and cost.

Work with product, design, IT, SRE, and business system owners; contribute code reviews, documentation, and technical guidance.

Qualifications

  • 5+ years of professional software development experience, including delivery of production applications across backend and frontend.
  • Strong Python skills with FastAPI or similar frameworks, asynchronous programming, REST APIs, SQLAlchemy/Pydantic or equivalent tooling, and PostgreSQL data modeling.
  • Hands-on experience with LLM tool calling, agent execution, or workflow orchestration; practical examples explaining design decisions, context and state management, and failure handling.
  • Experience integrating enterprise or third-party systems, including API contracts, data mapping, pagination, rate limits, and retries.
  • Understanding of OAuth 2.0/OIDC, authorization, role-based access control, and secure credential handling in applications.
  • Ability to build reliable asynchronous workflows using task state, concurrency control, idempotency, and recovery from partial failures.
  • Proficiency in TypeScript and Vue or React, including routing, state management, and reusable components. Vue 3 is preferred; willingness to adapt is essential.
  • Experience with automated and integration testing, Git, CI/CD, and Docker; ability to troubleshoot using logs and metrics and evaluate agents against representative tasks.
  • Clear communication with global, cross-functional teams and the ability to explain technical tradeoffs to non-technical stakeholders.

Nice to have

  • Experience extending agent harnesses, SDKs, or orchestration frameworks such as LangGraph, LangChain, or custom implementations.
  • Development of MCP servers, connectors, plugins, or SDKs; integrations with Microsoft Graph, Teams, SharePoint, Jira, ERP, or similar systems.
  • Experience with long-running workflows, human approval, durable task state, recovery, or agent evaluation frameworks.
  • Hands-on cloud deployment and operations experience, preferably AWS; familiarity with caching, queues, NoSQL databases, or vector search.
  • Electron development or plugins for desktop and productivity applications.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
