Lead Software Engineer

About this role
As a Senior Full-Stack Software Engineer, you will be a foundational hire at a pivotal moment in the company''s growth. You will take direct ownership of significant product and infrastructure work-streams, with a clear path to leading the engineers who follow you.

Responsibilities:

• Platform development – You will work across our real-time voice platform, customer dashboard, agent runtime, and analytics pipeline. Current projects include scaling our telephony infrastructure to handle billions of calls annually, building outbound calls management and reporting capabilities, and expanding self-serve functionality within the customer UI to support enterprise operations at scale.
• Feature ownership – You will own entire product lines end to end, from scoping and architecture through to delivery and iteration. Each work-stream you take on represents a minimum of $1M in ARR that is ready to be unlocked; your output will have a direct and measurable impact on the company''s growth and fundraising trajectory. Projects include collections agents, OCR document processing flows, permission systems, and outbound automation.
• Software architecture – You will design and build systems against strict performance and reliability constraints. This means understanding where the current architecture needs to evolve, making principled decisions under ambiguity, and building things correctly from the outset – the foundations you lay will underpin a multi-million-dollar platform.
• Forward deployment – Senior engineers work closely with customers. You will attend customer meetings, develop a deep understanding of how the product is used in practice, and translate that directly into product decisions. The best ratio of impact to effort comes from engineers who are as close to the problem as possible.
• Leadership – You will join as an individual contributor with the expectation of growing into a leadership role. The intention is for the engineers hired now to lead the next wave of fifteen or more engineers joining by the end of the year. Hiring, delegation, and mentorship will become a meaningful part of the role as the team scales.
