Senior Software Engineer

• Design, build, and ship features across Voice, Messaging, and Platform Services systems (APIs, routing logic, carrier integrations, messaging pipelines)
• Use AI coding assistants (Claude Code, Codex, GitHub Copilot, Cursor, or similar) as a core part of your daily workflow, and help less experienced teammates build the same fluency
• Evaluate, pilot, and recommend AI development tools and workflows for the broader engineering team; help set internal best practices and guardrails
• Design, build, and run AI agents to automate real engineering and operational work (testing, monitoring, incident triage, code migration, documentation) with appropriate guardrails and human review
• Partner with the team to integrate AI-assisted development into CI/CD, code review, and QA without compromising reliability or security
• Support production systems handling real-time voice and messaging traffic, including a weekly on-call rotation
• Collaborate directly with product management on technical scoping, estimation, and tradeoffs
• Write clear technical documentation, including for internal tooling and AI-assisted workflows adopted by the team

• 6+ years of professional software engineering experience, ideally including backend/API work, telecom/CPaaS, or high-reliability distributed systems
• Deep, hands-on daily fluency with AI coding tools: you can speak to specific workflows, prompting techniques, and where these tools genuinely help versus where they fall short
• Strong fundamentals: you evaluate and correct AI-generated code rather than accepting it, with solid grounding in data structures, system design, testing, and security
• Practical experience building and operating AI agents (orchestrating multi-step or tool-using agents via frameworks or APIs such as Claude Agent SDK, LangChain, or similar), not just single-shot prompting
• Experience with a modern backend language/framework (Node.js, Python, Go, or Java) and RESTful API design; this team is primarily Node with some Python
• Excellent written communication skills, with the ability to document decisions and workflows clearly for a distributed team
• Able to be in the Raleigh, NC office Wednesdays and Thursdays each week; unfortunately, this role is not able to sponsor work visas
• Bonus: experience with telecom protocols (SIP, SMPP), messaging standards (SMS/MMS/RCS), or carrier integrations
• Bonus: experience deploying agents into production systems (not just prototypes), including handling failure modes, cost and latency tradeoffs, and safety guardrails

• Work on infrastructure that's genuinely mission-critical: real calls, real texts, real customers, at scale
• Be part of a thriving company at the center of the rapidly growing CPaaS industry
• Join a small, senior team with real ownership and visibility into the product roadmap
• Shape how the entire engineering org adopts AI-assisted development, not just use the tools, but define how they're used
• Your future path here is wide open, with real room for professional growth
• Hybrid schedule based in Raleigh, NC (in-office Wednesdays and Thursdays)

• Comprehensive health coverage: medical, dental, and vision for you and your family
• Generous PTO plus 10+ paid company holidays
• 401(k) with a 4% company match
• Competitive compensation
• A fun, collaborative culture with team-building events and company-wide volunteer days
