Relay is fundamentally reshaping how goods move in an online era. Backed by Europe's largest-ever logistics Series A ($35M), led by deep-tech investors Plural (whose portfolio spans fusion energy and space exploration), Relay is scaling faster than 99.98% of venture-backed startups. We're assembling the most talent-dense team the logistics industry has ever seen

Relay's Mission is to free commerce from friction. Today, high delivery costs act as a hidden tax on e-commerce, quietly shaping what can be sold online and limiting who can participate. We envision a world where more goods move more freely between more people, making the online shopping experience seamless and accessible to everyone.

The Team

• ~110 people, more than half in engineering, product and data
• 45+ advanced degrees across computer science, mathematics and operations research
• Thousands of data points captured, calculated, analysed and predicted for every single parcel we handle
• An intellectually vibrant culture of first‑principles thinking, tight feedback loops and relentless experimentation
• Python, Rust and TypeScript - we keep things simple but use the right tool for the job
• Cross-platform Flutter apps with a deep focus on user experience
• Cloud-native on GCP with extensive use of BigQuery and Cloud Run
• Extensive use of ML modelling and LLM inference - no gimmicks here, this is our daily routine
• Emerging tech integrations, including robotics and IoT-powered operations
• Embed with enterprise clients during onboarding to deliver end-to-end technical success: integration, data quality, metrics alignment, and operational readiness.
• Partner closely with AMs, and external clients to define and implement a delivery performance metrics spec, and build client-specific dashboards that track these metrics in real time for both the client & Relay
• Improve and extend Relay's client integrations (APIs/webhooks/data feeds), increasing reliability, reducing exceptions, and lowering cost per shipment.
• Build tooling for integration observability (dashboards, alerting, reconciliation, replay) and drive measurable reductions in integration-related incidents.
• Stand up forecast ingestion and validation workflows to improve network planning accuracy and service levels.
• Feed repeatable learnings back into Relay's platform (templates, SDK patterns, metric contracts, connector blueprints) to scale onboarding and reduce bespoke work.
• Client metric alignment achieved with signed-off definitions and automated reconciliation.
• Material reduction in AM/Ops time spent on reporting disputes and manual data work.
• Improved integration uptime, lower error rates, faster issue resolution (clear SLOs).
• Forecast accuracy and timeliness improves; operational planning volatility decreases.
• New client onboarding time and marginal integration cost goes down quarter over quarter.
• Strong software fundamentals (APIs, distributed systems basics, data pipelines).
• Customer-facing maturity: you can run a room with technical + business stakeholders.
• Bias to shipping: you turn ambiguity into production outcomes quickly.
• Comfort in chaotic reality: inconsistent data, changing requirements, operational pressure.
• Generous equity, richer than 99% of European startups, with annual top-ups to share Relay's success.
• Private health & dental coverage, so comprehensive you'd need to be a partner at a Magic Circle law firm to match it.
• 25 days of holidays
• Enhanced parental leave.
• Located in Shoreditch, our office set-up enables the kind of in-person interactions that drive impact. We work 4 days on-site, with 1 day remote.
• Hardware of your choice.
• Extensive perks (gym subsidies, cycle-to-work, Friday office lunch, covered Uber home and dinner for late nights, and more).
• Aim with Precision: You define problems clearly and measure your impact meticulously.
• Play to Win: You chase bold bets, tackle the hard stuff, and view constraints as fuel, not friction.
• 1% Better Every Day: You believe that small, consistent improvements lead to exponential growth. You move quickly, deliver results, and learn from every experience.
• All In, All the Time: You show up and step up. You take ownership from start to finish and do what it takes to deliver when it counts.
• People-Powered Greatness: You invest in your teammates. You give and receive feedback with care and candour. You build trust through high standards and shared success.
• Grow the Whole Pie: You seek out win-win solutions for merchants, couriers, and our customers, because when they thrive, so do we.
