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.

- Lead the design, architecture, and development of native Windows desktop applications using Windows App SDK, WinUI (or related UI frameworks), C#, XAML, and — when needed — C++.
- Define and enforce best-practices for Windows desktop development across the codebase: code architecture, performance, memory usage, responsive UI, cross-version compatibility (Windows 10/11+), and maintainability.
- Drive accessibility efforts: integrate and validate support for accessibility APIs (e.g. Microsoft UI Automation or other relevant Windows accessibility frameworks), ensure UI controls, focus management, keyboard navigation, screen-reader support, and usability for users with disabilities.
- Collaborate closely with product designers, UX researchers, QA, and other stakeholders to shape feature planning, UI/UX architecture, and long-term roadmap for the Windows platform.
- Take ownership of full lifecycle of features: conception → design → implementation → testing → release → maintenance. Ensure quality, reliability, and consistency across releases.
- Identify, diagnose, and resolve complex bugs, performance bottlenecks, memory leaks, rendering issues, or compatibility problems — and propose robust architectural or design solutions.
Required:
- 3+ in Windows desktop application development using Windows App SDK, WinUI (or similar), C#, XAML — and ideally additional experience with native Windows code (C++, Win32/WinRT/COM).
- Deep understanding of Windows application architecture, including interop between managed code (.NET) and native code.
- Proven track record of designing, building, and shipping production-quality desktop applications, with an emphasis on reliability, performance, scalability, and maintainability.
- Strong experience with accessibility APIs on Windows (e.g. Microsoft UI Automation or similar), and a dedication to building accessible and inclusive software.
- Excellent software engineering fundamentals: OOP, design patterns, data structures, algorithms, memory management, multi-threading or asynchronous programming (where relevant).
- Experience leading technical design, mentoring other engineers, conducting code reviews, and making architecture-level decisions.
- Strong communication skills; ability to articulate tradeoffs, collaborate with cross-functional teams, and drive consensus.
- A user-centric mindset: focus on building polished, intuitive, and accessible experiences for end users.
Preferred / Bonus:
- Experience with writing automated tests for UI — unit tests, integration tests, UI automation tests; familiarity with relevant testing frameworks.
- Experience with performance optimization for desktop apps (memory usage, startup time, rendering performance, high-DPI support, responsiveness under load).
- Experience with localization/globalization, right-to-left UI support, internationalization, accessibility for multiple regions.
- Familiarity with telemetry, analytics, crash reporting, logging, and error monitoring in desktop applications.
- Previous experience in shaping CI/CD workflows, release pipelines, and deployment strategies for desktop applications.
- Demonstrated ability to take ownership of feature areas or modules and drive them long-term, including maintenance, refactoring, and technical debt management.
What we offer
- A high-impact role: you will define architecture, shape the future of our Windows product, and directly influence what millions of users see and experience.
- A collaborative, flat-structure engineering culture — you are not just a coder, but a builder and a decision-maker.
- Opportunities to lead — mentor others, steer technical direction, and grow into broader technical leadership (e.g. Tech Lead, Architect).
- Flexibility, autonomy, and responsibility: you define how to solve problems, own features end-to-end, and contribute to long-term product vision.
- A purpose-driven mission: building software that’s reliable, accessible, and user-centered — making a real difference for people.
