Senior Software Engineer – Kotlin Team | Build the Future of AI-Driven Testing

Hybrid – 2 days/week in Central London (with flexible working hours)

Are you a Kotlin engineer (or JVM dev keen to upskill) who thrives in fast-moving, product-led environments? Join a rising AI infrastructure company that’s transforming how teams generate and test high-quality data. Their API-driven platform helps dev and QA teams ship faster, stay compliant, and eliminate manual work – and they’ve just secured Series A funding to scale!

Responsibilities

• Build scalable, performant systems in Kotlin
• Shape architecture and technical direction as the platform grows
• Work closely with product to deliver high-impact features
• Help define a modern engineering culture with autonomy and ambition

Stack: Kotlin, Spring Boot, Hadoop/Spark, AWS/GCP, microservices, CI/CD
