Job Summary:
Bandwidth Inc. is a global software company that delivers exceptional experiences through voice, messaging, and emergency services. They are seeking a Senior Software Engineer to develop an AI voice agent platform into a revenue-generating SaaS product, focusing on building and shipping code that meets customer needs.
Responsibilities:
• Ship the Product: Build the SaaS platform layer that turns our AI voice agent into a multi-tenant, revenue-generating product — tenant management, partner APIs, configuration workflows, onboarding UX, operational dashboards, and the glue that holds it all together.
• Work Everywhere in the Stack: Backend services, frontend, infrastructure, AI pipeline — you go where the highest-priority work is. Role boundaries slow teams down; you ignore them.
• Close the Loop: Get features in front of real partners and real SMBs fast. You measure your work by what users do with it, not by what got merged.
• Lead Through Craft: You earn influence through code quality, smart trade-offs, and velocity — not title or tenure. You raise the bar through code review, design discussions, and pairing.
• Automate the Bottlenecks: When something in the dev cycle is slow or repetitive, your instinct is to script it, agent it, or eliminate it. You don't just build the product — you accelerate the system that builds it.
Qualifications:
Required:
• You understand software design, system architecture, and why things break at scale — not because you read about it, but because you've built through it.
• You've built and launched products that real customers use — ideally in a startup or high-growth environment. Prototypes and POCs don't count.
• You've embraced AI development tools as a core part of how you work. You use AI to move faster while your experience and judgment ensure the output is sound.
• When AI generates code, you know whether it's good — and more importantly, you know when it's subtly wrong.
• When you hit an unfamiliar domain, your instinct is to pick it up and move fast — using AI to operate across the full stack without sacrificing quality.
• Build the SaaS platform layer that turns our AI voice agent into a multi-tenant, revenue-generating product — tenant management, partner APIs, configuration workflows, onboarding UX, operational dashboards, and the glue that holds it all together.
• Backend services, frontend, infrastructure, AI pipeline — you go where the highest-priority work is. Role boundaries slow teams down; you ignore them.
• Get features in front of real partners and real SMBs fast. You measure your work by what users do with it, not by what got merged.
• You earn influence through code quality, smart trade-offs, and velocity — not title or tenure. You raise the bar through code review, design discussions, and pairing.
• When something in the dev cycle is slow or repetitive, your instinct is to script it, agent it, or eliminate it.
Preferred:
• Experience with real-time systems, voice/telephony, or conversational AI
• Hands-on experience with LLMs, agentic AI, prompt engineering, or model fine-tuning
• Experience building multi-tenant SaaS platforms or B2B2B products
