About Prelude Prelude is redefining how companies authenticate and onboard users - turning what's traditionally a cost center into a growth lever. Our flagship product lets businesses send OTP codes with the best price-to-conversion ratio on the market, dynamically selecting the most effective channel in real time (optimized SMS, WhatsApp, and more) while actively blocking spam and fraud that legacy providers miss. Founded in 2022 by former Zenly team members who lived the pain of broken SMS authentication firsthand, we're already serving fast-growing companies across Europe and are expanding into the US. But authentication is only the starting point - we're building the platform for trust at scale, with an ambitious roadmap of market-defining products ahead. Why join us Today, we're a team of 60 and growing, based in Paris, building products that power secure and high-performance user onboarding for companies across the world. We believe small, highly skilled teams outperform large, fragmented organizations, and we are intentional about staying focused on impact, quality, and speed. We operate with a flat org structure and value in-person collaboration, which helps ideas move faster, decisions stay grounded, and teams take full ownership of what they build. Our values Care We care deeply about our customers, our teammates, and the quality and reliability of what we ship. Bias for Action We move fast, test in the real world, and iterate quickly rather than over-optimizing in theory. Ownership We take responsibility end to end, from identifying problems to delivering outcomes and learning from results. About the role Internal tooling is not a backlog item at Prelude — it's a strategic lever. As we scale from 50 to a much larger team, the speed at which engineering, ops, sales, support, and finance can operate depends on the tools we put in their hands. You'll own that surface. You'll build the internal tools and AI-powered automation that make every team at Prelude move faster, ship with confidence, and spend their time on the work that actually matters. You'll work directly with internal stakeholders to find friction and turn it into functional, reliable software — and you'll be our edge in AI engineering, evaluating and integrating the tools that define how a modern company operates. Here are some examples of projects : Interconnect the various internal tools we use (hubspot, linear, plain and more) Optimize the way we calculate and aggregate our billing Build flows and use AI to automate our internal processes (invoicing/reporting/support) This is a high-ownership IC role on the Platform team, with direct access to your internal customers from day one. What will you be doing? Owning the design, development, and maintenance of internal tools used daily across engineering, ops, product, sales, support, and finance Building agentic AI workflows that automate repetitive internal processes and unlock new capabilities for our teams (fraud review, customer support triage, GTM workflows, ops dashboards, and more) Working directly with stakeholders across all teams to identify friction and turn it into functional solutions, with feedback loops measured in days, not quarters Evaluating and integrating the latest AI engineering tools (Claude, Cursor, n8n, Dust, and whatever comes next) and setting the standard for how Prelude leverages them internally Contributing to our polyglot codebase and collaborating with the broader engineering team on shared infrastructure, schemas, and APIs Designing and building internal dashboards on top of our data layer (DynamoDB, Clickhouse and Postgres) to give every team visibility into what they need to act on Participating in on-call rotations for the internal platform you build What are we looking for?
