As a Senior Python Engineer at Send, you’ll play a crucial role in building and evolving the core of our SaaS platform. This is an exciting opportunity to work with modern technologies within a microservices architecture, developing new platform features, enhancing existing functionality, and ensuring the scalability and reliability of our backend systems. You’ll be part of a collaborative, agile team, contributing to key technical decisions and mentoring others along the way.

At Send, although we’re enthusiastically exploring the potential of AI for underwriting, and in particular, Agentic AI, we’re very mindful that these solutions cannot be deployed in isolation. We’re building for the long-term, laying the right foundations to enable businesses to experiment with AI and realise tangible value more quickly. This role is part of a team with special focus in this key emerging area.

If you’re an experienced Python Engineer (ideally with some practical experience in AI frameworks and tools) and ready to take on your next challenge and thrive in a dynamic, fast-paced environment, we’d love to hear from you.

We are the leading insurance platform, trusted by world-class insurers to help them navigate complex risks.

Our platform helps commercial insurers, MGAs and reinsurers modernise underwriting, cut friction, and grow profitably in complex markets.

We are the only platform purpose-built for multi-operating models. Our platform combines deep industry expertise with the ability to support a range of strategies and operating models.

Over the past two years, Send has experienced significant growth, expanding our team by over 50% to more than 120 people. At the start of 2024, our team was primarily based in the UK and Poland. Since then, we’ve taken major steps toward building a global presence, with team members now located across the UK, US, India, and Ireland—all working collaboratively toward our vision of becoming the market-leading software platform for agile insurers.

From 2017 to 2022, we bootstrapped our growth journey, building a profitable and stable company. In November 2022, following a year of strong customer and team growth, we secured $10 million in Series A funding to accelerate our expansion across the UK and US, as well as to further enhance our product development. We’re proud to have the support and expertise of our investors, Mercia and Breega.

We are now preparing for our Series B round and are excited about the growth acceleration this will enable.
