[Remote] Software Engineer, GTM AI - Python

Note: The job is a remote job and is open to candidates in USA. Telnyx is an industry leader in global connectivity, and they are seeking a Software Engineer to build and operate AI-native backend systems for their go-to-market motion. The role involves designing multi-agent architectures, integrating complex business systems, and managing services from prototype to production.ResponsibilitiesDesign and build multi-agent AI systems in Python that handle complex, multi-step business workflows - qualification, email generation, routing, enrichment, and outbound orchestrationArchitect model-agnostic abstraction layers that decouple business logic from LLM providers, enabling flexibility across Claude, GPT, and open-source modelsBuild and operate backend services (FastAPI/Flask) deployed on Kubernetes with CI/CD, managing the full lifecycle from deployment configuration to production reliabilityDesign tool-use patterns for AI agents - structured function calling, multi-step reasoning, state management across conversation turns, and graceful handling of model failuresBuild integrations across external systems (CRM, enrichment APIs, outreach platforms, Slack) with proper error handling, retries, rate limiting, and data contractsInstrument and monitor AI systems in production — build observability into agent behavior, track success rates, detect regressions, and debug non-deterministic failuresDesign and run experiments (A/B tests, prompt variations, model comparisons) with proper evaluation infrastructure to measure what's actually workingSkills2+ years of software engineering experience building backend services in PythonProduction experience building multi-step AI agent systems — stateful workflows where models make decisions, call tools, and operate across multiple turns, not single-shot API wrappersStrong understanding of LLM internals as they affect system design: context window management, token budgets, cost/latency/capability tradeoffs across models, structured outputs, and strategies for handling hallucination and refusalsExperience testing and evaluating non-deterministic AI systems — you understand that assert output == expected doesn't work and have built or used alternativesSolid software architecture fundamentals: API design, state management, fault tolerance, and graceful degradation when upstream services failProduction experience with containerized deployments (Docker, Kubernetes) and CI/CD pipelinesExperience integrating with external APIs at scale — auth flows, rate limiting, retries, data normalization, and managing the operational complexity of multiple third-party dependenciesProficiency with SQL and data systems for building targeting, enrichment, and analytics pipelinesBuilt observability into production systems — structured logging, tracing, alerting, and monitoring that you actually use to debug issuesHigh ownership: you deploy your own code, investigate your own incidents, and close the loop between what you shipped and how it performsExperience with specific GTM/RevOps systems (Salesforce, Apollo, Lusha, enrichment providers) or similar complex business platformsBackground in growth engineering, marketing automation, or revenue operations toolingExperience with Slack bot development or conversational AI interfacesContributions to or experience with open-source AI agent frameworksFamiliarity with ArgoCD, StatefulSets, or Kubernetes operations beyond basic deploymentsCompany OverviewYour one-stop shop for infrastructure at the edge.
