Software Engineer IV, Platform

About the role

The Software Engineer IV owns and delivers end-to-end capabilities that support core product experiences, applied research, and underlying application systems. This role operates primarily across service backends, APIs, persistence layers, data integrations, and supporting infrastructure, while contributing to frontend applications and demonstrations as needed. The role is responsible for delivering capabilities from design through deployment, including developing backend services, designing and maintaining APIs, modeling and persisting application data, building integrations, and supporting the infrastructure required to operate services reliably. The engineer owns the full lifecycle of assigned services, including implementation, testing, infrastructure, deployment, monitoring, and operational support. This role owns larger components or problem areas and leads requirements gathering and architecture for multi-sprint efforts. It makes informed tradeoffs across performance, scalability, reliability, security, maintainability, and implementation complexity. The engineer identifies dependencies and risks, breaks down complex work into actionable tasks, contributes to planning and estimation, and delivers predictable outcomes with minimal supervision. This role works closely with product managers, designers, data scientists, and other engineers to define requirements, clarify constraints, and deliver reliable technical solutions. The role coordinates with engineers from other teams, produces clear technical documentation, participates in design discussions and code reviews, mentors less-experienced engineers, and contributes to improvements in team tools, frameworks, and engineering practices. In partnership with cross-functional teams, this role helps bring new capabilities from concept to production, emphasizing practical engineering judgment, maintainable implementation, operational readiness, and reliable delivery.

Working conditions Employees may be called upon to participate in in-person meetings, trainings, or company functions at Knowmadics offices or other designated locations. Travel in support of business operations may also be required, and employees are expected to comply with these obligations as part of their position.
