Sr. Software Engineer (AI Voice & Messaging Agents)

• Engineering Fundamentals Are Non-Negotiable: 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.
• Product Shipping Experience: You've built and launched products that real customers use — ideally in a startup or high-growth environment. Prototypes and POCs don't count.
• AI as a Force Multiplier, Not a Crutch: 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.
• Deep Instincts Over Blind Trust: When AI generates code, you know whether it's good — and more importantly, you know when it's subtly wrong.
• Full-Stack Fearlessness: 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.

• →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.

Comfortable in Ambiguity: Requirements are evolving, priorities shift weekly, and the roadmap is measured in weeks, not quarters. That energizes you.Entrepreneurial Instinct: You think about the product, not just the code. You care whether what you built actually moves the business forward.Pragmatic over Clever: You prefer boring technology that scales over shiny technology that breaks. You build guardrails and observability — then move fast inside them.Low Ego, High Ownership: You're here to ship a product, not to be the smartest person in the room. You'll pick up whatever task moves the team forward, whether it's glamorous or not.

• 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

• A real product, not a demo: A deployable, sellable platform with paying customers.
• Weekly improvement loops: Shipping and learning from real partner and customer feedback every week.
• Operational confidence: Clear dashboards, measurable quality, fast incident response, and releases you can trust.
• Scale trajectory: A system designed to grow into tens of thousands of agents without collapsing under its own complexity.

Startup pace and ownership — without building distribution from scratch.A serious communications backbone (global network + deep telephony expertise) already underneath you.A team that's ready to shift from "the concept works" to "customers pay."
