Senior Staff Software Engineer, Agentic Platform
Location : London, Bulgaria, Serbia and Lithuania
ABOUT THE ROLE
Tide is hiring a Senior Staff Software Engineer to lead the architecture of our agentic platform.
You will shape the shared capabilities that allow AI systems to operate safely, reliably, and at scale across Tide. That includes context, orchestration, tool execution, trust controls, observability, and evaluation. You will participate in key build versus buy decisions, integrate external components where they accelerate us, and ensure we own the parts that matter most for Tide’s trust, data advantage, and long-term platform leverage.
WHAT YOU WILL DO
Define the architecture for Tide’s agentic platform
Drive the design of shared services such as context APIs, tool layers, policy controls, and auditability
Partner with product, data, security, and engineering teams to turn use cases into reusable platform capabilities
Set standards for reliability, safety, scalability, and developer experience
Provide technical leadership across teams and unblock critical decisions
Implement cost-management and routing logic to optimize LLM spend across different providers
Design and build automated evaluation pipelines to measure agent reasoning accuracy and safety trajectories
WHAT WE ARE LOOKING FOR
Deep experience building platform or infrastructure systems at scale
Strong judgement across APIs, distributed systems, data, and cloud-native architecture
Track record of leading complex cross-team technical problems
Experience integrating third-party platforms without losing control of core architecture
Strong understanding of reliability, security, and observability
Experience with AI platform components is valuable, but not essential
Experience in highly regulated industries (Fintech, Healthtech, etc.) where safety and compliance are core to the product is highly desirable
WHY THIS ROLE MATTERS
This role will help determine whether Tide builds isolated AI pilots or a reusable platform that compounds value across productivity, risk, and connectivity.
OUR TECH STACK:
Java, Spring Boot and JOOQ to build the RESTful APIs of our microservices (but we welcome people who are used to any strongly typed general purpose programming language!)
Event-driven architecture with messages over SNS+SQS and Kafka to make them reliable
Primary datastores are MySQL and PostgreSQL via RDS or Aurora (we are heavy AWS users)
Docker, Terraform, EKS used by the Cloud team to run the platform
DataDog and Rollbar to keep it running
GitHub with Sonarcloud, Semgrep and solid testing to power the CI/CD pipelines - new joiners are encouraged to have something deployed to production in their first 2 weeks
Angular 2+ with ngrx on Web, Flutter for the Mobile App
Fivetran/Snowflake/Looker for the BI insights and Python/Faust/Flask/Tecton + some ML libs for the automated decisioning and risk management
WHAT YOU'LL GET IN RETURN
Flexible working options
Group Life Insurance
Vitality Health Insurance, with a proactive focus on mental and physical wellbeing
25 days holiday with the ability to buy extra days
3 days for L&D or volunteering time off per year
We invest in your development with a £1,000 professional L&D budget per year
Access to ‘salary sacrifice’ benefits such as Cycle to Work scheme and pension contribution
Spacious brand-new office near Old Street with an all-day snacks bar
Enhanced family-friendly leave
Sabbatical leave
