Job description

We believe that communication belongs to everyone. TextNow is redefining how people connect by combining simplicity, intelligence, and accessibility. We’re a team of curious builders using technology to make communication more affordable and powerful for millions of users every day.
As a Software Developer - Backend, you won’t just build services—you’ll shape the systems, architecture, and tooling that make them possible. At TextNow, Members of Technical Staff combine leadership and hands-on coding to enable the highest leverage opportunities possible. Being able to operate strategically, as well as diving into the lowest-level details, is a must. You’ll take technical ownership of key backend domains and work across mobile, web, and data to create faster, smarter, more reliable systems.
AI and automation are at the core of how we build. You’ll use them to accelerate development, improve performance, detect and resolve issues faster, and continuously raise the bar for backend development excellence.
We’re hiring Members of Technical Staff across multiple levels (intermediate/senior/staff+). Whether you’re an experienced developer looking to lead complex systems, or an early-career developer eager to grow, we’ll align your title and scope based on experience and impact.
This role is about impact at scale. You’ll shape how TextNow builds and operates its backend systems—using AI and automation to make development faster, decisions smarter, and experiences more seamless for millions of users worldwide.

What You'll Do

  • Design, develop, and sustain high-performance, scalable backend services using Go microservices and modern cloud-native tooling.
  • Lead architectural modernization and modularization to improve scalability, observability, and developer velocity.
  • Define and own the entire lifecycle of your systems: API design, data modeling, deployment (CI/CD), live-traffic monitoring, integration and load testing, telemetry & data analysis, experiment design (A/B tests), and continuous iteration.
  • Influence and evolve our architecture: propose and lead initiatives to decompose monoliths, migrate legacy code, build shared frameworks and reusable service components; evaluate new backend technologies and lead their adoption.
  • Apply AI-driven tools and automation frameworks to speed up development, code analysis, testing, and reliability.
  • Leverage intelligent telemetry, analytics, and optimization pipelines to improve service performance and resilience.
  • Define observability standards, telemetry pipelines, and fault-tolerance strategies for production-grade distributed systems.
  • Partner closely with product, mobile, and data teams to deliver seamless, high-quality experiences across all platforms.
  • Drive technical discussions, mentor developers, and influence strategic direction across backend and infrastructure domains.

Who You Are

  • A technical leader with the ability to create and lead roadmaps/initiatives that align to high-level business objectives.
  • Deep expertise in Go, with additional experience in PHP for legacy systems is a bonus
  • Proven track record of architecting modular, maintainable, and high-performance microservices.
  • Strong background in system design, observability, and performance optimization.
  • Experience with AWS, Kubernetes, Argo CD, Protobuf, CI/CD pipelines, and auto-scaling architectures.
  • Experience using AI and automation to improve developer velocity, reliability, or system intelligence.
  • A collaborative technical leader who thrives in fast-moving environments and mentors others to excel.
  • Passionate about building resilient, intelligent, and highly scalable backend systems that serve millions of users.
  • You architect for observability, reliability, and production-readiness: you understand instrumentation, SLOs/SLIs, fault-tolerance, runbooks, incident triage, scalable telemetry pipelines, and production diagnostics for backend systems.
  • You have been a technical leader (not just an individual contributor): you’ve influenced roadmap decisions, contributed to multi-team initiatives, mentored/led developers, driven culture/process improvements, and interfaced with senior developer/product leadership.
