Senior Software Engineer

Do you want to be part of the future of value transfer?

Are you excited about solving problems that have never been solved before?

Looking for a values‐led company that truly invests in your growth?

We’re looking for a Senior Software Engineer to join our product‐engineering organisation and help build a next‐generation data and intelligence platform that powers blockchain analysis products used around the world.

In this role, you'll collaborate closely with data scientists, product teams, intelligence specialists, and fellow engineers to evolve a platform designed for large‐scale batch and streaming data, blockchain‐agnostic solutions, and sophisticated data‐processing challenges that bring clarity to how value moves across the crypto ecosystem.

We want someone who tackles high‐risk challenges first, brings fresh ideas, validates hypotheses with data, and thrives on solving hard problems.

The Impact You Will Have

You'll be joining a team of experienced, curious, and fearless engineers who enjoy pushing boundaries. Our data and intelligence platform is central to every customer‐facing product, and you’ll see the impact of your work quickly. We embrace openness, lean thinking, and early delivery- encouraging engineers to challenge convention and build innovative solutions from the ground up.

Key Responsibilities

What you will do:

• Write clean, functional code and thorough tests
• Evaluate different technical approaches to complex problems across various non‐functional requirements
• Build infrastructure and leverage cutting‐edge cloud technology and AI so you're spending less time on repetitive tasks and more time solving customer problems
• Collaborate openly with both technical and non‐technical teams
• Take full ownership of your code from PR to production
• Contribute to projects across our platform—ranging from forensics tools to entity exposure APIs and blockchain visualisation products

Skills, Knowledge & Expertise

You will be a great fit if you:

• Take pride in writing clean, well‐tested code
• Use data to inform feature decisions and iterations
• Focus on outcomes—not just release milestones
• Embrace AI to enhance your productivity and impact
• Communicate proactively across teams
• Are not afraid to experiment, fail fast, and learn quickly
• Are eager to learn new technologies and challenge established processes

Our ideal candidate has:

• 3-5 years of Scala experience
• Experience delivering and maintaining distributed data processing systems using Big Data tools, lakehouse platforms, and workflow orchestration (experience with Spark, Databricks, or Airflow is a plus)
• Experience building with cloud platforms such as AWS, Azure, or GCP
• Experience working with AI tools or platforms (LLMs, predictive models, ML infrastructure)
• Strong understanding of distributed systems patterns and trade‐offs
• Knowledge of non‐functional requirements—scalability, reliability, performance, observability

Bonus points for:

• Interest in functional programming
• Experience with streaming concepts (delivery semantics, ordering, partitioning)
• Infrastructure‐as‐code experience (Terraform, CloudFormation)
• Running applications in containerised environments (Docker, Kubernetes, Helm)
• Interest in cryptocurrency or blockchain technology
