In today's world, where the effective use of AI is key to business success, high-quality data is essential for AI to generate accurate and reliable outputs. As we enter an era where humans and AI coexist, primeNumber is committed to removing the barriers to data utilization and creating a world where everyone can live alongside the true value of data. ◼︎Our Services TROCCO: A cloud-based ETL platform that enables seamless data integration and management across various systems.

As we enter a more mature phase of development, we face increasingly complex architectural and user needs. We're looking for engineers who can lead core product development — from architectural design and technology selection to driving execution in collaboration with cross-functional teams. You’ll also help evolve the development organization itself by addressing challenges such as technical debt management, tacit knowledge codification, and continuous productivity improvement.

You will have a key role in evolving our SaaS platforms — TROCCO and COMETA — for long-term scalability and AI-era readiness. Key areas of focus include: ・Long-term product architecture, feature development, and performance improvements ・Technical decision-making and reviews (e.g., refactoring, resolving technical debt) ・Collaborating with PdMs, CSEs, QA, and others to execute on roadmap ・Improving team engineering processes, tooling, and knowledge sharing ・Mentoring junior engineers, pair programming, and code reviews ・Participating in company-wide projects for integrating generative AI into products ◼︎Why Join Us as a Software Engineer ・High Ownership: Lead everything from design to implementation to decision-making. Shape the technical core of the product and the team. ・Product Impact: Go beyond just building — co-define and deliver value that’s actually used by real customers. ・Build for the AI Era: Drive real-world implementations of generative AI and data productivity tools — both internally and in-product. ◼︎Reference Links (Japanese) ・Our Culture and 8 Elements https://note.primenumber.co.jp/m/m01089dc05116?_ga=2.232109911.913922094.1751890806-1818199376.1724208067 ・CTO Office Interview https://note.com/gtnao/n/n0f61927f0924?magazine_key=mca2b9cd5c5d3&_ga=2.232109911.913922094.1751890806-1818199376.1724208067 Team Structure (Product Development HQ – ~33 FTEs, ~22 Contractors) ・1 CTO ・4 PdMs / 3 PMMs ・17 Software Engineers / 3 SREs ・2 Designers / 1 Technical Writer ・1 QA Engineer / 1 Security Engineer Tech Stack ・Languages: Ruby (Rails), TypeScript (React), Java (Embulk) ・Infra: AWS (mainly EKS, ECS Fargate) ・IaC / Monitoring: Kustomize, Terraform / CloudWatch, New Relic, Redash, Rollbar ・CI/CD: CircleCI, GitHub Actions ・AI Tools: Claude, GitHub Copilot, Gemini ・Communication: GitHub, Slack, Google Workspace, Confluence, Miro ・Others: Okta, 1Password
