Описание

Mid-to-Senior Java Software Engineer role for a small, high-performing market maker in London. Primary focus is Java backend development, with secondary ownership of Python ETL/data ingestion into AWS and PostgreSQL. The growing team works on data ingestion and building tooling for the wider firm.

Обязанности

Build and enhance Java backend services (APIs, batch jobs, integrations) used across the business
Write clean, testable code with solid engineering discipline (testing, code review, debugging, production support)
Maintain and extend Python-based ingestion/ETL (pragmatic plumbing, not heavy data engineering)
Work with PostgreSQL (schemas, migrations, performant queries, data validation)
Improve service reliability: monitoring/logging, sensible alerting, and predictable deployments via CI/CD

Требования

10+ years of experience building production systems or equivalent ability
Strong Java fundamentals: OO design, APIs/services, concurrency basics, testing
Some UI development
Comfortable with SQL/PostgreSQL
Some Python experience enough to manage and improve existing ETL/ingestion
Any finance or markets exposure
Familiarity with common AWS patterns for running services and pipelines
Java (primary), Python (secondary), AWS, PostgreSQL, Git, CI/CD, logging/monitoring

Условия

Full-time employment
Lean team with high impact and strong growth runway
Broader scope than pure application development
