Our AI agents learn from your best human agents and improve with every interaction, helping organizations understand their customers, deliver better experiences, increase operational efficiencies, and build a lasting competitive advantage.

Our AI agents and human agents operate on a single platform with shared context, allowing Agentic AI to resolve issues, advance deals, and eliminate busywork through automation while seamlessly handing conversations to humans when needed, with full context preserved.

Market-leading brands, including Randstad, Motorola Solutions, Netflix, the San Diego Padres, the Colorado Rockies Baseball Club, and Cal Athletics, trust the company. the company is backed by Andreessen Horowitz, GV, ICONIQ Capital, and T-Mobile.

Being a Dialer

At the company, AI isn’t just a feature; it’s how our teams do their best work every day. We put powerful AI tools in every employee’s hands so they can move faster, think bigger, and achieve more.

We believe every conversation matters. And we’ve built the platform that turns those conversations into insight and action, for our customers and ourselves.

We look for people who are intensely curious and hold themselves to a high bar. Our ambition is significant, and achieving it requires a team that operates at the highest level. We seek individuals who embody our core traits: Scrappy, Curious, Optimistic, Persistent, and Empathetic.

Your role

As a Sr. Software Engineer on the Developer Platform team, you will lead the design and development of the APIs, events, and frameworks that empower external developers to build integrations and plug‑ins for the company. This platform is central to scaling the company's integration ecosystem, ensuring third‑party developers have the robust tools they need to create seamless experiences for our customers. This includes backend public APIs, event frameworks, frontend plug‑in frameworks, and client libraries.

You will own a set of core components within the Developer Platform team, translating developer workflows and business needs—identified in partnership with our technical product manager—into high-quality, scalable technical solutions. You will help shape the 6‑12 month technical direction for the platform, break down complex requirements into clear, actionable deliverables, and solve technical challenges through shared tools and patterns.

You’ll collaborate closely with engineering teammates, product leaders, and external developer stakeholders. You will be expected to operate with little guidance, make pragmatic business and technical trade‑offs, and mentor other engineers through design, implementation, code review, and production support.

This position reports to our Developer Platform Director and will require a hybrid working arrangement based out of our Vancouver office.

What you’ll do

• Own the full development lifecycle of public APIs and platform features, from design and implementation to testing and production monitoring.
• Collaborate with product managers, engineering teammates, and external stakeholders to identify and translate developer needs into scalable technical solutions.
• Mentor other engineers through design reviews, code reviews, and onboarding support.
• Contribute to the long‑term technical direction and architecture of the developer platform.

Skills you'll bring

• Engineering Experience: Professional experience designing, launching, and maintaining scalable backend or full‑stack platform systems.
• Technical Proficiency: Strong proficiency in Python or JavaScript, with hands‑on experience building APIs, webhooks, and distributed systems.
• Domain Expertise: Familiarity with platform‑level concepts such as OAuth, permission models, rate limits, and event delivery.
• Operational Excellence: A pragmatic approach to testing, debugging, and troubleshooting production systems within an Agile environment.
• Communication & Mentorship: Ability to drive technical design, mentor engineers, and clearly explain trade‑offs to both technical and non‑technical stakeholders.
• AI-Forward: Strong interest in Agentic AI and experience using AI‑assisted coding tools (e.g., Gemini, Claude) for development.
• Bonus Points: Experience building developer platforms, integrations, data pipelines (ETL), or high‑throughput async systems (Redis, message queues).
