The Role
Lead technical design and architecture across the stack during a platform shift to an agentic platform. Own system design for durability, orchestration, performance, cost, and observability. Drive technical decisions, code and design reviews, and ship quickly as a hands-on individual contributor while enabling future engineering growth and potential people management.

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.

Ravio is growing fast, which means you can too. We’ve established ourselves as the European leader in our space serving more than 1,200 clients, and now have our sights set on becoming the global go to place for compensation data and tools for managing compensation.

Joining a startup and scaling it into a global product is one of the most challenging and rewarding experiences a career can offer. If that sounds exciting to you, you’re in the right place.


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

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 Lead 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 Lead 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.

Why join Ravio?

  • Shape an agentic platform from its early stages, with senior engineering peers and a high autonomy bar.

  • Opportunity for fast-tracked professional growth at a scaleup backed by world-class investors alongside a smart, energetic team.

  • Blend of IC work and leadership, giving you both hands-on impact and career growth.

  • Remote-friendly, flexible work culture with a high degree of ownership.

  • While we’re very focused, we also know how to have fun in the process.

  • Build a meaningful product that helps people get paid fairly and competitively in their careers.

Compensation & benefits
  • £110,000 - £150,000

  • Company ownership (everyone gets a meaningful equity stake in Ravio)

  • 37 days paid time off (25 days holiday + 4 wellness days + 8 public holidays)

  • Up to 6% pension matching scheme

  • £60 a month wellness allowance (Invest in your physical wellbeing, on us)

  • £500 per year Learning and Development budget

  • Private healthcare cover (on a medical history disregarded basis) with AXA

  • Personal worldwide travel insurance - just in case

  • Income protection insurance (for full peace of mind in case you cannot work because of sickness or disability)

  • 16 weeks fully paid birthing parent leave, followed by 4 weeks at 50% pay. For non-birthing parents, we offer 8 weeks fully paid leave.
