About Telnyx
Telnyx is an industry leader that's not just imagining the future of global connectivity—we're building it. From architecting and amplifying the reach of a private, global, multi-cloud IP network, to bringing hyperlocal edge technology right to your fingertips through intuitive APIs, we're shaping a new era of seamless interconnection between people, devices, and applications.
We're driven by a desire to transform and modernize what's antiquated, automate the manual, and solve real-world problems through innovative connectivity solutions. As a testament to our success, we're proud to stand as a financially stable and profitable company. Our robust profitability allows us not only to invest in pioneering technologies but also to foster an environment of continuous learning and growth for our team.
Our collective vision is a world where borderless connectivity fuels limitless innovation. By joining us, you can be part of laying the foundations for this interconnected future. We're currently seeking passionate individuals who are excited about the opportunity to contribute to an industry-shaping company while growing their own skills and careers.
Telnyx Edge Compute is our serverless platform — it lets developers deploy Go, Python, and Java functions directly onto Telnyx's global network, running application logic milliseconds away from end users. It's how our customers handle webhooks, voice and messaging events, and AI inference at the edge, without touching a server.
We're looking for a Go engineer to join the Edge Compute squad and help us build the platform behind it. You'll be working on the runtime, the deployment pipeline, the CLI, and the control plane that makes "write a function, deploy it globally" feel effortless. The systems you build will be used by every developer on Telnyx — so the bar for reliability, performance, and developer experience is high.
What you'll do
- Design and build the Go services that power our serverless runtime, function deployment pipeline, and global control plane.
- Make the platform feel great to use — clean APIs, a sharp CLI, predictable behaviour, useful error messages. Developer experience is a feature, not an afterthought.
- Diagnose and fix latency, throughput, and reliability issues across a system that spans data centres around the world.
- Build automation and tooling that lets us operate the platform safely at scale.
- Participate in on-call for the systems you build.
What we're looking for
- 2-5 years of professional backend software development experience.
- Proficiency in Go, or strong experience in a comparable backend language (Rust, Java, C++) with a real interest in writing Go day-to-day.
- Solid grounding in distributed systems — you've debugged a service-to-service problem in production and know what kinds of things go wrong at the edges.
- Experience running services in a high-availability environment, including being on-call.
- Comfort designing APIs that other engineers (internal or external) will actually use.
- Working knowledge of relational databases — when to reach for one, and when not to.
Bonus points for
- Experience building developer tools, platforms, runtimes, or anything where your users are other engineers.
- Familiarity with serverless or edge-compute platforms (Cloudflare Workers, Fastly Compute, Lambda, Fly.io, Deno Deploy, etc.).
- Experience with our stack: Docker, Kubernetes, Consul, Prometheus, RabbitMQ, Jenkins.
- Experience operating systems across multiple regions or data centres.
- Open source contributions, particularly in the Go ecosystem.

- Collaborate with cross-functional teams — including ML researchers, product, and platform engineers — to translate agentic product requirements into robust runtime infrastructure.
- Develop and optimize real-time distributed systems, microservices, and event-driven architectures powering agentic task execution.
- Design and implement sandboxed execution environments for safe agent use of tools, code execution, and external API calls.
- Implement and maintain monitoring, alerting, and performance metrics covering agent run success rates, token consumption, latency, and cost attribution.
- Evaluate and integrate emerging agentic frameworks, LLM APIs, and tooling ecosystems to continuously improve platform capabilities.
- Write clean, modular, and well-tested code while following best engineering practices in a rapidly evolving problem space.
- Participate in code reviews to ensure the quality, maintainability, and scalability of runtime components.
- Provide mentorship and technical guidance to junior engineers navigating the unique challenges of agentic systems.
Skills you’ll bring
- 3–6 years of experience in distributed systems, platform engineering, or ML infrastructure, with exposure to LLM-based or agentic systems strongly preferred.
- Strong understanding of agent architectures, including ReAct, plan-and-execute, and multi-agent coordination patterns.
- Deep knowledge of context management, prompt lifecycle, tool-call protocols (e.g., function calling, MCP), and agent memory strategies (short-term, episodic, and long-term).
- Experience integrating and managing external tool ecosystems, including web search, code interpreters, databases, and third-party APIs.
- Familiarity with retrieval-augmented generation (RAG) and how retrieval fits into broader agentic pipelines.
- Understanding of LLM output reliability challenges — hallucination, non-determinism, and retry/fallback strategies at runtime.
- Proficiency in Go and Python 3 (experience with Rust or TypeScript is a plus).
- Strong understanding of distributed systems, microservices, and event-driven architectures suited to long-running agent tasks.
- Passion for real-time performance optimization, including streaming responses, async execution, and parallel tool invocation.
- Experience with API design using OpenAPI, Swagger, or equivalent, with an eye toward agentic interaction patterns.
- Knowledge of gRPC or equivalent RPC protocols for inter-service communication within agent runtimes.
- Experience with Docker and Kubernetes, including managing long-running or stateful agent workloads in containerized environments.
- Familiarity with cloud platforms (GCP preferred, AWS/Azure optional), including managed services relevant to agentic workloads such as queuing, secrets management, and compute autoscaling.
- Hands-on experience with Infrastructure as Code tools like Terraform or Ansible.
- Knowledge of CI/CD frameworks and continuous delivery practices, with comfort shipping infrastructure in a fast-moving research-adjacent environment.
