Senior Staff Software Engineer, Agentic Platform
United Kingdom
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
