Job description

We Help Companies Get Compensation Right. What we get paid at work has a massive impact on our lives, and it’s one of the biggest factors in hiring and retaining talent - and yet so many companies struggle to get it right. They simply have no choice but to rely on poor data and unsophisticated tools for their pay decisions. That’s why we created Ravio.

We help many of the world’s most innovative and ambitious companies build stronger teams and reach their goals through better compensation. Our real‑time data platform brings compensation into the modern age, tracking the market across all compensation types from salary to equity and benefits.

The role

We’re looking for a Lead 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.

Requirements

• 8+ years commercial engineering experience, with a track record of technical leadership during platform shifts – owning architecture, driving decisions, raising the bar through code review and design review, especially where LLM assisted engineering has become the standard
• System design depth as your headline strength. 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

  • MCP servers as the tool layer

Compensation & Benefits
