Full stack developer

Roles & Responsibilities

We’re looking for an Engineering Manager who treats engineering management as a systems problem, not a career milestone.

You’ll lead engineers while staying close to the technical core—owning architecture, modeling decisions, and execution quality in a domain where correctness matters as much as velocity.

Technical & Product Ownership

• Build and evolve core platform features
• Design and ship APIs, services, and integrations that power billing automation, usage metering, invoicing, revenue recognition, and financial reporting.
• Model complex financial workflows
• Work deeply on pricing logic, proration, true-ups, multi-currency handling, approval workflows, and event-driven billing pipelines—where small decisions have long-term consequences.
• Make architectural trade-offs
• Balance “ship it now” against “live with it forever” while scaling systems that process high-volume usage data and real-time financial calculations.
• Stay technically fluent
• You won’t write code every day, but you’ll review PRs, catch subtle bugs, and guide design discussions with confidence.

Team Leadership & Management

• Lead and grow the engineering team
• Mentor and manage engineers across experience levels, setting clear expectations and raising the bar on ownership, execution, and quality.
• Create high-output systems
• Establish clear problem definitions, focused execution cycles, code reviews that actually catch issues, and enough slack for engineers to think—not just ship.
• Debug team dynamics like software
• Observe signals, form hypotheses, intervene deliberately, and measure outcomes—whether the issue is delivery, alignment, or collaboration.
• Build the team intentionally
• Design interviews that surface real problem-solving ability, not just pattern matching. At this stage, every hire shifts the average.

Cross-Functional Collaboration

• Work closely with Product, Finance, and Customer Success to translate real-world contract terms into correct, scalable systems
• Partner with stakeholders to solve ambiguous problems where requirements evolve and trade-offs are unavoidable
• Ensure systems remain accurate, auditable, and compliant as the product scales
