Join us as a Software Engineer to build the AI execution layer where go-to-market agents do the work, not just answer questions. Taizen builds purpose-built AI agents for Product Marketing, Sales Enablement, and Revenue teams. Our AI agents connect to tools like Gong, Salesforce, Hub Spot, and Slack, then proactively run recurring workflows without waiting to be prompted. Why take the bet We're early-stage, so the risk is real: timelines move, and equity is worth what the company becomes, not what it's valued at today. Here's why we think it's worth it. We're two ex-Spotify engineers who've shipped and scaled software used by millions, funded, and building with real customers every week. There's also a shift worth betting on. What they can't do is untangle a vague problem, design a data model that holds up under real usage, or debug something failing in a way nobody expected. After a few years in the job, the thing that sets you apart isn't how fast you type, it's your judgment, and that's exactly what this role leans on. Competitor moves, deal objections, buyer feedback,



and coaching gaps are trapped across call recordings, CRM notes, documents, and Slack threads. Show sales leaders where deals are advancing or stalling, while helping BDRs research territories and identify the right accounts to bring into pipeline AI roleplay: Let reps practise against voice-based AI buyers grounded in real deals, objections, and battlecard content AI Win/loss interviews: Interview buyers after a deal and turn the conversations into structured insights without someone scheduling every call The Stack You won't just work inside this stack, you'll help decide where it goes. Frontend: React Backend: two services, a Node/Type Script core and a Python agent service Retrieval: our own vector store written in Rust, SOTA late-interaction retrieval Data: Postgres + Mongo DBAgents: our own harness, not an off-the-shelf framework, and model-agnostic ML: a mix of our own and open-source models;
