Concrete: durability and consistency under failure, multi-service orchestration, data platforms, performance and cost at scale, observability and ops fluency * Senior-level fluency in TypeScript and Node, comfortable across the backend (PostgreSQL, GraphQL or HTTP APIs, GCP-shaped infra) * Comfortable owning code in a distributed monorepo with multiple deployable services * Ships fast under product pressure - we're moving from PMF to scale and the role needs that pace Nice to have * Production experience with agentic systems - tool calling, multi-step orchestration, LLM evals. * Workflow engines (Temporal, Cadence, Step Functions) - even if not Temporal specifically * MCP, Anthropic SDK, or other LLM platform work * Building developer platforms, internal SDKs, or framework-shaped surfaces * Eval-driven development, prompt engineering at scale, LLM-judge harnesses * React or another modern frontend framework ## Description We're looking for a Staff Software Engineer to join our engineering team and play a major role in our technical leadership during a significant platform shift. Ravio is moving from a traditional SaaS posture to a platform built around agents - parent agents fronting our compensation data, specialist agents underneath, durable workflows, an MCP-based tool layer, and an eval harness to maintain consistency. You'll own architecture and technical design across the stack: the customer-facing web app, the agentic platform, and the shared infrastructure connecting them. You'll bring system design depth - the kind that holds up under load, failure, and coordination across services and teams. You'll continue to raise the bar on code quality, reliability, and the technical decisions that shape what we ship. This is a hands-on individual contributor role - leading technical decision-making and tackling the hardest problems we encounter. There are also upcoming opportunities to move into management as our company continues to grow, if you wish., * Frontend + React + Typescript + GraphQL (Apollo Client) + Playwright + Jest + Storybook + Chromatic + Mantine + GCP (Cloud Run) * Backend + Typescript + PostgreSQL + GraphQL Yoga + Jest + Auth0 + GCP (Cloud Run, Cloud SQL, Cloud Storage + more) * AI / agentic platform + Opus/GPT/Gemini/and many more model families + Vertex/Bedrock/Foundry - Cloud deployed models + Temporal - durable workflow engine + MCP servers as the tool layer + AI gateway (Bifrost) for logging, routing, governance + Eval harness (Phoenix) - golden queries, LLM-as-judge + Memory layer (Neo4j) * All the other good stuff + GitHub Actions + Datadog + Figma + Slack + Linear The opportunity at Ravio right now From your perspective, there are three critical things to look for when evaluating this role: a company going places, a strong engineering culture, and a role that gives you a true opportunity to have impact as a technical leader. Ultimately it's for you to decide whether that's true in our two-way street interview process. Here's a summary of where we are right now and what you can expect as a starting point. There's a lot happening at Ravio right now. We've just raised our Series A led by tier 1 US investors Spark Capital, and have acquired the benchmarking business of our competitor - Compete. We've got new joiners starting almost every week, and we're rapidly expanding outside of our core markets in Europe. We need you to help us maintain our velocity and continue to build a scalable org and product. Our core benchmarking product is at product-market fit, and we have a couple of new modules in the 0-1 phase. This means we're at an exciting stage that involves 0-to-1 building in some areas, and building for scale in others. That's true across the business, we're continuing to expand and experiment, while systemising and doubling down on what is already working well from our seed phase. Beyond the core product, we're building Ravio's agentic platform - parent agents fronting our compensation data with specialist agents underneath, durable workflows on Temporal, an MCP-based tool layer, and an eval harness to maintain consistency. It's a platform engineering effort with the same care and rigour we apply to the rest of the product. A Staff engineer joining now would help shape the foundations of how Ravio's product is built for the next phase. We'd like to think Ravio is a great place to be a Staff engineer - we have technical leaders who know first hand the importance of creating space and focus for engineering teams to do their best work. And you'll be working alongside many accomplished and world class teammates, who are energised by the work they do and have a high bar for themselves and their colleagues. ## Related Videos - [Under the Hood of Building on Lovable](https://www.wearedevelopers.com/videos/100032-under-the-hood-of-building-on-lovable) - [Livecoding with AI](https://www.wearedevelopers.com/videos/1201-livecoding-with-ai) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Putting the Graph In GraphQL With The Neo4j GraphQL Library](https://www.wearedevelopers.com/videos/257-putting-the-graph-in-graphql-with-the-neo4j-graphql-library) - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 138 - Are you secure about this?](https://www.wearedevelopers.com/magazine/486-dev-digest-138-are-you-secure-about-this) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers)
