About The Position

Bandwidth is a global software company that helps enterprises deliver exceptional experiences through voice, messaging, and emergency services. We are seeking a Sr. Software Developer (Infrastructure) to help build the platform and tools that enable Bandwidth engineers to ship better software, faster. This role is crucial in making Bandwidth an AI-first engineering organization. The Software Infrastructure team owns the "paved road" – the platform, tools, and systems that allow every Bandwidth engineer to build and ship with confidence. This position will play a key role in advancing that mission, with a focus on leveraging AI as a platform for development.

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: ability to close the loop, ship, and measure.
• Bachelor's degree or equivalent experience.

Nice To Haves

• Experience building or operating an LLM proxy, AI gateway, or model routing layer.
• Experience working on a Developer Experience or Software Platform team.
• Experience writing infrastructure as code (Terraform, CDK, CloudFormation).
• Experience building MCP servers or integrating AI tools with internal systems like Jira, Slack, or GitHub.
• Experience building tools or services other developers use (open source experience counts).
• Experience working in a startup or high-ambiguity environment where requirements needed to be defined.

Responsibilities

• Design and operate Bandwidth's AI infrastructure layer, including our LLM gateway, model routing, and cost controls, to enable safe and cost-effective AI tool experimentation by all engineering teams.
• Build and maintain the "paved road" of developer tooling and platform services to 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.
• Connect AI to existing engineer systems (Jira, Confluence, Slack, GitHub) to ensure context flows seamlessly.
• Measure key metrics such as engineer velocity, build times, reversion rates, and actual shipping outcomes, focusing on impactful results over vanity metrics.
• Stay ahead of the curve on agentic workflows, guiding teams to evolve from manual coding to orchestrating AI systems for complex tasks.

Benefits

• 100% company-paid Medical, Vision, & Dental coverage for you and your family with low deductibles and low out-of-pocket expenses.
• Four weeks of PTO for all new hires.
• PTO Embargo: No work interruptions during time off.
• Additional PTO earned through volunteer hours and Bandwidth challenges.
• "Mahalo moments" program for significant life events.
• 90-Minute Workout Lunches.
• Unlimited meetings with a nutritionist.
