Bandwidth • Raleigh, NC

About The Position

Bandwidth is a global software company that helps enterprises deliver exceptional experiences through voice, messaging, and emergency services. The Software Infrastructure team owns the "paved road" - the platform, tools, and systems that let every Bandwidth engineer build and ship with confidence. This role will play a key part in making Bandwidth an AI-first engineering organization by designing and operating the AI infrastructure layer, including LLM gateway, model routing, and cost controls. The goal is to enable every engineering team to experiment with AI tools safely and cheaply, while also building and maintaining developer tooling and platform services to help engineers ship faster with less friction. The role also involves driving adoption of AI coding tools, connecting AI to existing systems, measuring key engineering metrics, and staying ahead of agentic workflows.

Requirements

• 5+ years of experience building and operating web services in production
• Hands-on experience with cloud infrastructure, especially AWS
• Strong coding skills in Python, Go, TypeScript, or similar
• Experience with platform services: CI/CD, secrets management, developer portals, internal tooling
• Familiarity with LLM APIs and the tradeoffs involved in model routing, token cost management, and AI observability
• Experience building tools or services that other engineers depend on day-to-day
• A results-driven mindset. You close the loop, you ship, you measure.
• Bachelor's degree or equivalent experience

Nice To Haves

• You've built or operated an LLM proxy, AI gateway, or model routing layer
• You've worked on a Developer Experience or Software Platform team before
• You've written infrastructure as code (Terraform, CDK, CloudFormation)
• You've built MCP servers or integrated AI tools with internal systems like Jira, Slack, or GitHub
• You've built tools or services other developers actually use (open source counts)
• You've worked in a startup or high-ambiguity environment where you had to define the requirements yourself

Responsibilities

• Design and operate Bandwidth's AI infrastructure layer, including our LLM gateway, model routing, and cost controls, so every engineering team can experiment with AI tools safely and cheaply.
• Build and maintain the "paved road" of developer tooling and platform services that help engineers ship faster with less friction.
• Drive adoption of AI coding tools (Claude Code, Copilot, and others) by building enablement systems, prompt libraries, MCP server integrations, and internal tooling that make AI feel obvious, not optional.
• Connect AI to the systems engineers already use (Jira, Confluence, Slack, GitHub) so context flows to wherever work happens.
• Measure what actually matters: engineer velocity, build times, reversion rates, and real shipping outcomes. Not vanity metrics.
• Stay ahead of the curve on agentic workflows, helping teams evolve from writing every line of code to orchestrating AI systems that handle the toil.

Benefits

• 100% company-paid Medical, Vision, & Dental coverage for you and your family with low deductibles and low out-of-pocket expenses.
• All new hires receive four weeks of PTO.
• PTO Embargo. When you take time off (of any kind!) you’re embargoed from working. Bandmates and managers are not allowed to interrupt your PTO – not even with email.
• Additional PTO can be earned throughout the year through volunteer hours and Bandwidth challenges.
• “Mahalo moments” program grants additional time off for life’s most important moments like graduations, buying a first home, getting married, wedding anniversaries (every five years), and the birth of a grandchild.
• 90-Minute Workout Lunches and unlimited meetings with our very own nutritionist.
