Scala Software Engineer

Job Description

As a Scala Software Engineer, you will play a key role in the design and development of TheHive, our flagship incident response platform used by thousands of security analysts worldwide. You will join a highly skilled and passionate team, including one of our founders, working in close collaboration with Product and QA. This is a strategic technical role where your expertise will directly influence the evolution of the product, its architecture, and its long-term scalability.

Responsibilities

• Design and develop new user-facing features through robust and scalable APIs.
• Contribute to the evolution and improvement of the product’s core architecture.
• Participate in the design and conception of new product features and future solutions.
• Identify, analyze, and fix bugs to ensure product reliability and performance.
• Contribute to upgrading and maintaining libraries and frameworks within our technical stack.
• Develop and maintain high-quality unit tests to ensure long-term code stability.
• Actively participate in Scrum ceremonies and collaborative technical discussions.
• Proactively contribute to architectural decisions and technical improvements.

Our backend technical stack includes: Scala, Play Framework, Akka, JanusGraph, Tapir, Macwire, and Git.

Requirements – Technical Skills

• Apply strong development fundamentals: challenge requirements, avoid technical dogmatism, think in terms of testing, and write clean, maintainable, reusable code.
• Master core software design principles and common development patterns.
• Understand business use cases, user behaviors, and real-world operational needs.
• Anticipate long-term technical impacts and scalability considerations.
• Approach technology as a means to serve product and user needs — not as an end in itself.

Ideal Candidate Traits

• Takes time upstream to understand, discuss, and refine needs before building.
• Thinks strategically rather than executes tasks mechanically.
• Can weigh trade-offs and articulate the pros and cons of architectural choices.
• Anticipates future technical constraints and scalability challenges.
• Is proactive and comfortable proposing improvements to architecture and engineering practices.
• Has solid experience with Scala and modern backend development (experience with our stack is a strong plus).
