Senior Software Engineer, Engine Dynamics

About the role:

We are looking for a highly motivated and experienced Senior Software Engineer to join the Engine Dynamics team and help tackle some truly foundational challenges in how Forter's Decision Engine evolves, scales, and maintains its reliability and agility over time. The role is most suitable for backend engineers that love the business of software building, and are passionate about the complex and delicate process of making big systems simpler. It's all about tackling the challenges of running truly big software in production, and is suitable for engineers that can operate well in high and low abstraction levels.

It's important to note that this is not a platform role. The team is serving the decision engine only, and its problem solving toolset derives from business rationale and value. The team will be building systems that will function as part of the engine, and will not develop generic development infrastructure for other teams to use.

About the team:

At Forter, where ideas drive innovation, complexity is the main friction that slows ideas from becoming reality - and thus our biggest productivity challenge.

The Engine Dynamics team owns the insight-to-production experience for Forter's Decision Engine. This means looking at the Forter engine development process as a product, and making strategic changes to how we develop features in it, either analytical or product-offering features. It means reducing complexity, improving confidence, reducing production faults and reducing the mental burden shared by all engine development teams. It requires understanding Forter's core business well, and knowing what a good development experience looks like.
