Role
Who you are
- If you're excited about building something that doesn't exist yet, keep reading
- You’re a builder who thrives at the frontier of AI agents, customer experience, and e-commerce
- We’re looking for someone who can own critical domains in our AI agent ecosystem
- 3+ years of software engineering experience building technical B2B products, ideally in CX, e-commerce, or AI automation
- AI-native mindset — you already use tools like Claude, Cursor, v0, or ChatGPT daily to build and ship faster
- Full-stack fluency — React, TypeScript, Node.js, APIs, integrations, data modeling
- Comfort working directly with clients and solving complex, real-world problems
- Curiosity and a builder’s DNA — you like figuring things out, not just following specs
- Product judgment — you're able to build product with agency and autonomy
What the job involves
- We're a small, distributed team that punches way above our weight
- Every person here has outsized impact because we've built leverage into everything we do
- This philosophy makes us faster and, frankly, more fun to work with
- We're building agents that don't just respond to customers—they remember them, learn from every interaction, and connect experiences across channels
- You’ll build new capabilities, shape evaluation and QA systems, and collaborate closely with product, design, and leadership to create the infrastructure for the future of e-commerce and CX
- You won’t just execute—you’ll bring strong opinions, push back when something isn’t worth building, and help us choose the right bets
- Building complex systems that blend UX, AI, and integrations
- Designing evaluation and QA processes that make agents continuously improve
- Shipping new capabilities that change how shopping and CX happen
- Juggling multiple initiatives while keeping the big picture in mind
- Debating trade-offs, pushing back on requests, and shaping the why behind what we build
- Build new agent capabilities end-to-end and make them work seamlessly across platforms
- Translate messy customer workflows into elegant product features and deployment opportunities
- Design and ship evaluation and QA systems that improve agent performance over time
- Expand our integrations ecosystem by shipping new platforms and enterprise connections
- Own platform automation and onboarding to help customers go live in days, not weeks
- Work across multiple initiatives at once, balancing speed with thoughtful trade-offs
- Partner with product, design, and leadership to shape what gets built—and what doesn’t

Our take
Customer service plays a pivotal role in the success or failure of commerce businesses, with a good customer service experience proven to build trust and power repeat purchases. With this in mind, Siena supplies a platform for companies to automate their customer service responses with AI capable of responding in the brand's voice and acting with "almost human" empathy.
Siena's platform can be employed for a number of customer service interactions, such as answering queries or arranging refunds and returns. The idea is to reduce the workload of customer services teams, with the platform handling over 80% of day-to-day interactions so that human team members are free to focus on more important or unique cases.
The idea is certainly an interesting one, and with its potential to save commerce companies thousands on customer support it is no surprise it boasts a number of clients already. 2023 funding will go towards hiring, go-to-market plans, and further development - with the ultimate goal for Siena to become a fully autonomous agent.
