The Role
This company is building the Agentic Operating System for procurement, where AI agents are the product, not an add-on. They're tackling a complex problem in a large market, backed by leading investors, with significant ARR growth and hundreds of enterprise customers. This isn't another feature-factory SaaS.
You'll join a dedicated platform team, serving an engineering org of 45+ people scaling rapidly. This isn't a DevOps or SRE role; you'll write production TypeScript, owning the shared foundations and developer experience for everyone else. Your impact is direct: enabling multiple daily production deploys and setting the pace for the entire engineering team. This is a senior or staff-level role.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The Work
- Evolve a serverless AWS architecture (Lambda, DynamoDB, Aurora, EventBridge) for 10x scale, multi-region high availability, and data residency.
- Own and improve GitHub Actions pipelines and Pulumi infrastructure-as-code, enabling multiple daily production deploys.
- Build and tune Datadog dashboards, SLOs, and alerts that proactively flag issues before customers are impacted.
- Write production TypeScript to build and enhance internal developer tools and shared platform foundations.
What You Bring
- Deliberate specialisation in platform or developer experience at a cloud-native SaaS company (50-500 engineers). This isn't a DevOps or SRE role.
- Production-grade TypeScript experience. Not just Bash or YAML scripting.
- Deep, hands-on knowledge of AWS serverless (Lambda, DynamoDB, Aurora, EventBridge, IAM, networking) and their trade-offs.
- Experience refactoring infrastructure-as-code (Pulumi, CDK, Terraform, or SST) and building robust CI/CD workflows.
- Proven ability to build reliable observability: dashboards, SLOs, and alerts that genuinely pre-empt customer-facing issues.
