Senior Development Engineer (Customer Operations/AI Agents)

• We’re looking for a senior engineer to help build and scale the AI agents behind our Sales and Customer Service teams. These agents handle real conversations with real customers every day, answering questions, qualifying leads, quoting moves and resolving issues across phone, chat and messaging.
• You’ll own them end to end, from designing how they reason and which tools and data they can use, to the evaluation, guardrails and observability that keep them accurate, on-brand and safe in production.
• You’ll work closely with our Sales and CS leaders and the agents who use these tools on the front line, so you can see the impact of your work in conversion, response times and customer satisfaction. This is a hands-on role for someone who wants to move LLM-powered systems past the demo stage and into something thousands of customers rely on.

How our engineering teams deliver

• We're product-led and agile. Most teams run Scrum with two-week sprints, but we care far more about outcomes than rituals. Engineers are trusted to challenge assumptions, adapt processes, and ship things that matter.

Senior engineers here are not heads-down implementers. You'll:

• Work closely with product, data, and commercial stakeholders
• Influence technical direction and architectural decisions
• Balance speed with long-term sustainability
• Regularly ship meaningful improvements to production

Our technology

• We're pragmatic and cloud-first, running on AWS, with the flexibility to choose the right tool for the job:
• Exploring: Go, Rust, React, Node.js
• Core stack: Python, Vue.js & Nuxt, TypeScript
• Legacy (retiring where we can): Java, PHP, Angular
• You don't need experience in everything, we value strong fundamentals and good engineering judgement over keyword matching.

What you'll be doing

• Designing, building, and operating production-grade systems that scale
• Tackling complex technical challenges across backend, infrastructure, data flows, and AI/ML pipelines
• Writing clean, pragmatic, well-tested code with long-term maintainability in mind
• Collaborating with technical and non-technical stakeholders to shape solutions
• Championing testing, observability, and quality improvements
• Mentoring engineers and raising the technical bar across the team

You'll thrive here if you have

• Experience in a scale-up or fast-growing product environment
• Strong backend engineering skills (Go, Java, Python, or similar)
• A solid understanding of distributed systems, scalability, and performance
• Experience with CI/CD, modern deployment practices, and cloud infrastructure
• Comfort working with ambiguity and evolving requirements
• A bias toward action — shipping value quickly, then iterating
• A collaborative mindset and the ability to influence beyond your code
• Bonus: exposure to AI/ML systems, marketplaces, logistics, pricing, or e-commerce
