Senior Software Engineer II – Engine Dynamics

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 infrastructure layer of Forter's decision engine. We treat the engine development process as a product: reducing complexity, improving confidence, lowering production faults and easing the mental load on all engine development teams.

About the role:

We're looking for an experienced Senior Software Engineer II to own the infrastructure that takes Decision Engine changes from code to safe production rollout - complex testing setups, gentle and verified deployment flows, observability, and the tooling that lets engineers develop and debug with confidence at scale. You'll lead multi‑quarter initiatives with impact that clearly goes beyond a single team, combining hands‑on backend work with technical leadership to simplify complex systems and raise reliability for multiple engine teams.

What you will be doing:

• Own the engine's path to production - its testing infrastructure, deployment flow, and the critical verifications that keep releases safe, gentle, and fast.
• Lead multi‑quarter, team‑scoped projects that change how we build, validate and ship engine changes, from problem definition to rollout.
• Remodel key parts of the Decision Engine and its tooling to reduce toil, simplify workflows, and make complex changes safer and faster to deploy.
• Own critical engine platform components (scale, precision, validation, fault detection, observability, developer tools) used by multiple engine teams.
• Turn ambiguous engine‑level problems into clear plans, breaking them into milestones, aligning stakeholders, and driving execution.
• Mentor engineers in and around the team, raising the bar via design reviews, pairing, and clear technical guidance.

Who are you?

• 7+ years of experience building backend systems in large‑scale, mission‑critical environments, acting as a technical lead for substantial projects.
• Hands-on ownership of the infrastructure behind shipping complex systems safely — testing frameworks, deployment and rollout mechanics, verification gates, observability, and the debugging tools that let engineers move fast with confidence.
• Experience working on high-scale production systems, ideally in areas involving data-intensive flows or distributed data stores.
• Deep familiarity with cloud‑native environments (AWS / GCP / Azure, Kubernetes, Docker) and production‑grade observability and deployment practices.
• Proven track record of leading multi‑quarter, team‑scoped projects end‑to‑end, including collaboration with product/analytics/other engineering teams.
• Strong skills in one or more of Python / Java / Kotlin / Rust / Go, and solid understanding of modern backend architectures.
• Demonstrated subject‑matter expertise in at least one relevant domain (e.g., distributed backends, developer productivity tooling, testing/deployment infrastructure, runtime reliability, data/stream processing) and comfort working in high‑ambiguity areas.
• Experience defining and driving engineering standards adopted beyond a single team.
