Our Engineers are responsible for all aspects of the software development lifecycle. You will get the opportunity to work across our entire stack building features which deliver AI capabilities to some of the biggest names in the insurance industry.

We are developing a modern real-time AI platform using technologies like PyTorch, Ray, k8s (helm + flux), Terraform, Postgres, Flink on AWS, React & Typescript. We operate a fully Python stack except for frontend and infrastructure code. We are very big fans of Infrastructure-as-Code and enjoy Agile practices.

As a team, we're driven by a relentless focus on delivering real value to customers at speed. We embrace modern engineering practices such as automated testing, continuous monitoring, feature flags, and on-demand production-like environments to support frequent, reliable releases.

Our team is tackling several exciting challenges, including:

• Deploying all changes, including complex machine learning models, reliably to customers within 15 minutes
• Building a real-time, configuration-driven platform that seamlessly adapts to diverse customer needs
• Ensuring autoscaling and cost-efficient model serving in production, with robust support for ML monitoring and experimentation
• Centralised reporting/metrics for both the business and our customers

Role Summary In response to a growing number of Japanese customers, we’re looking to strengthen our technical team in the region. We are hiring an experienced Senior Software Engineer who can support our customer deployments, develop new capabilities, and collaborate with teams in Japan and the UK to ship awesome features. You’ll be working extremely closely with our two Data Scientists and our Engagement and Commercial team in Japan, as well as our UK-based Engineering team to make this happen.

Given you will be a standalone Engineer in a new time zone, it’s important that you are able to operate independently, have strong communication skills, love to document your work effectively, and can manage internal and external stakeholders effectively. Strong soft skills will really set you apart!

We are looking for an engineer who is eager to expand their expertise by contributing to impactful product features. You'll play a key role in improving the lives of millions of insurance policyholders globally, working with a modern and powerful technology stack that includes:

• Python for application development
• Terraform for AWS infrastructure provisioning
• Kubernetes (with Helm and Flux) for managing services
• GitLab for CI/CD and version control
• AWS as our infrastructure platform
• PostgreSQL for application data and event sourcing architecture
• Apache Flink for real-time service interactions and state management

Responsibilities

• Work with different stakeholders across the business and directly with our customers to understand a problem space within your area, propose solutions, and own the end to end delivery of complex projects.
• Own and maintain specific parts of our stack with best in class engineering practices.
• Write comprehensive unit, integration and end-to-end automated tests in the backend for customer-facing features.
• Lead on platform-facing work, using infrastructure-as-code (AWS, terraform, k8s) to ensure our platform is reliable and scalable.
• Take a lead in code reviews, provide constructive feedback, and keep to date with latest trends in the industry.
• Provide mentoring to other members of the Engineering and Data Science teams.
• Lead in the continuous improvement of the processes and ways of working for the engineering team.
• Manage feature rollouts with multiple releases per day by utilising feature flags, metrics, logs and alerting.
• Champion the Engineering and Sprout company values

Requirements

• Business proficiency in both Japanese and English language - you’ll collaborate with Japanese customers, as well as colleagues in both Japanese and English.

• Technical proficiency

• Strong experience working in fully cloud-hosted environments (e.g. AWS)

• Strong proficiency in software architecture using Python or similar backend programming languages

• Solid RDBMS experience, preferably with PostgreSQL

• Experience building RESTful APIs (e.g. FastAPI) and real-time data processing pipelines

• Bonus points for experience with Infrastructure-as-Code frameworks (e.g., Terraform) and Kubernetes, Apache Flink and Flux

• Deep understanding of modern software development lifecycles, including code quality, pull requests, code reviews, CI/CD, QA, and production releases in an agile, fast-paced environment

• Collaborative by nature, with excellent communication, teamwork abilities, and stakeholder management skills.

• Comfortable and confident speaking directly with customers, including non-technical individuals.

• Strong problem-solving skills with the ability to think critically and creatively

About Sprout.ai Founded in London in 2018, Sprout.ai was born from a simple belief: insurers should be there for policyholders in their time of need. Long delays, manual processes and outdated systems meant customers were often left waiting weeks for outcomes at their most vulnerable moments. We set out to change that.

Today, Sprout.ai is redefining insurance automation for insurers. Acting as the intelligence layer at the heart of operations, we bring advanced AI, digitisation, and data-driven processes to transform how claims and underwriting decisions are made.

Our mission is to make every interaction between insurers and policyholders accurate, fast, and fair, and our vision is to become the world’s most trusted insurance intelligence partner, powering billions of safe, explainable decisions for global insurers.

Sprout.ai integrates seamlessly into existing systems to deliver real-time claims automation and actionable insights, enabling expert teams to focus on complex cases with speed and empathy. Insurers use our platform to overcome legacy challenges, cost pressures, fraud risk, and regulatory demands, achieving tangible results including:

• Up to two-thirds of claims processed automatically
• 99% accuracy
• Significant gains in customer satisfaction and operational efficiency

Backed by leading insurers and recognised with industry awards and ISO 27001 certification, Sprout,ai is the insurance intelligence automation platform injecting insights into claims and underwriting — changing insurance, for good.
