Senior Software Engineer - Python

Job SummaryCONVO is seeking a Senior Software Engineer - Python to build the shared runtime, orchestration, tool registry, and SDK powering its agentic platform. You’ll develop asynchronous, distributed backend services using Python, FastAPI, and graph-based orchestration, while working with vector/graph databases, MCP-compatible tools, and robust workflow management. You’ll focus on scalable agent execution, reliable tool integration, observability, failure handling, and developer-friendly SDKs that enable teams to build and operate domain agents efficiently.Technical missionDesign and implement the shared runtime, planner, tool registry and SDK that other teams use to build and operate domain agents.Key ResponsibilitiesImplement asynchronous orchestration and planning services that translate intents into executable agent workflows.Build and maintain the tool registry, tool-call contracts, agent SDK and runtime APIs.Integrate graph and vector persistence for workflow state, memory and retrieval.Implement MCP-compatible interfaces and adapters for internal and external tools.Design failure handling, retries, idempotency, timeouts, tracing and deterministic replay where applicable.Create developer documentation, reference implementations and automated tests for consuming teams.Required Technical CapabilitiesMinimum experience: 6+ years in backend or distributed-systems engineering, including 2+ years with workflow orchestration, LLM applications or agent runtimes.Advanced Python, including asyncio/concurrency and production FastAPI services.Experience with workflow or agent orchestration, preferably LangGraph or an equivalent graph-based runtime.Practical use of graph databases and/or vector databases in production systems.Strong API and SDK design, schema versioning and backward-compatibility discipline.Understanding of MCP, structured tool calls and secure tool execution.Automated testing of distributed, asynchronous and failure-prone workflows.Preferred ExperienceAgent memory, multi-agent coordination or planner/executor patterns.OpenTelemetry tracing and evaluation telemetry for agent workflows.Sandboxing, policy enforcement and tenant-aware runtime design.Expected deliverables / acceptance evidenceVersioned agent runtime and orchestrator services.Tool registry and MCP-compatible contract layer.Documented agent SDK with reference agents and integration tests.Operational telemetry and failure-management mechanisms.Primary InterfacesWorks with all pod engineering teams, the Architecture Office, Agentic Governance and QA/evaluation roles.What We Have For YouGreat compensation package, medical benefit for you and your family, free lunch, annual performance-tied increments & performance recognition awards and a great lean and agile work culture!Convo endorses a culture of diversity in all aspects and aims to build a diverse team of amazing individuals!
