Role Description We’re hiring a Senior Backend Engineer (.NET) to help scale our client, a field service management platform powering large-scale inspection operations. You’ll work on the core backend (APIs, business logic, data layer) behind the company’s workflow, form builder, and report engines—focusing on simplifying a mature codebase and building scalable, configuration-driven systems that support enterprise clients without custom development. This is a senior IC role with real ownership over system design and backend architecture as the platform evolves toward cloud scale. Key Responsibilities - Design, build, and maintain scalable backend systems using .NET - Simplify and refactor a mature, feature-rich codebase (improving structure, clarity, and maintainability) - Develop clean, consistent, and consumer-friendly REST APIs - Design modular, well-bounded system components - Build and enhance configuration-driven platform capabilities (no-code/low-code style abstractions) - Optimize database performance (queries, execution plans, indexing) - Ensure system reliability (logging, failure handling, data integrity) - Collaborate closely with cross-functional teams (frontend, mobile, QA) Qualifications - Strong experience with .NET (Core and/or Framework) - Solid experience with Entity Framework and SQL Server - Strong SQL skills (query optimization, debugging performance issues) - Proven experience building and designing REST APIs - Strong systems thinking and ability to design modular, scalable architectures - Experience working with production systems and maintaining long-term code quality Requirements - Experience refactoring complex or legacy systems (Nice to Have) - Experience building configuration-driven or extensible platforms (Nice to Have) - Familiarity with AWS or cloud-based architectures (Nice to Have) - Experience deploying applications on IIS (Nice to Have) - Exposure to large-scale enterprise systems (Nice to Have) Benefits - High-impact role shaping a product at a key scaling stage - Work on a platform used by large enterprise clients - Strong growth trajectory toward global expansion and Gartner recognition - Competitive Package paid in USD

• Design, develop, and maintain backend services in Python 3.11 using Django / DRF • Lead architectural discussions and contribute to long-term technical strategy • Work with MySQL and Redis to optimize performance and scalability • Build and improve RESTful APIs for internal and external integrations • Collaborate with Product, Compliance, and Business teams to deliver impactful features and automate back office processes and workflows. • Investigate and resolve production issues, identify bottlenecks, and reduce tech debt • Apply best practices in Git workflows, CI/CD pipelines (TeamCity, GitHub Actions), and code quality • Mentor and develop engineers through code reviews, pairing, and technical guidance • Support security and compliance requirements with pragmatic, scalable technical solutions

• Design, build, and evolve our public API product, the core interface through which developers access Photoroom's AI capabilities. • Ship features used by both self-serve developers and large enterprise customers, ensuring the API remains reliable, scalable, and easy to integrate. • Own the API surface end-to-end: from design decisions (naming, versioning, structure) to implementation, performance, and long-term maintainability. • Iterate quickly based on real usage, we ship multiple times per week — using data and user feedback to prioritise what matters most. • Collaborate closely with product, machine learning, backend, and sales teams to ensure the API delivers real value to users.

• Incorporarse a un equipo multidisciplinar y participar en la construcción de un proyecto greenfield desde su inicio. • Diseñar, desarrollar y evolucionar APIs y microservicios desde la fase de definición hasta su puesta en producción. • Colaborar activamente en la definición de estándares técnicos, buenas prácticas y calidad del código. • Integrarse en flujos de trabajo basados en control de versiones, integración continua y despliegue continuo. • Comprender en profundidad los sistemas para proponer e implementar soluciones técnicas adecuadas a los retos del negocio.
