Hi
Workonomics are partnering with a company you likely haven't heard of by name, but have almost certainly interacted with before.
Their invisible technology helps tackle online fraud. Every time you use your debit or credit card online, their fully-automated, real-time platform makes your end-to-end purchasing journey safer.
In Cyber Week 2025, the company processed nearly $10B of online payments and stopped a significant volume of new, sophisticated AI agent-initiated fraud attempts.
Their London team is now hiring a Senior Infrastructure Engineer to help design and implement database solutions to handle and store petabytes of data.
Their focus is on scalability, low latency, high throughput, and geo-distributed database systems, capable of ingesting terabytes of data every second.
This role will suit a backend-oriented engineer who's comfortable building & managing database infrastructure at scale, with experience / knowledge of:
- designing large-scale db solutions that reliably handle worldwide operations
- both relational (e.g MySQL, Postgres, MariaDB) and NoSQL dbs (e.g Aerospike, Cassandra, ScyllaDB, DynamoDB, ElasticSearch)
- AWS infrastructure
- Bash / Python / Go
- Terraform
- Kubernetes
- distributed systems
