Senior Software Engineer, Core Platform

As a Senior Software Engineer, Core Platform , you will be a key contributor driving the design, implementation, and evolution of FloQast's foundational backend systems. You are a "systems thinker" who will build and optimize critical platform capabilities, including our end-to-end data platforms, core services, and robust authentication/authorization frameworks. Working in a high-growth environment, you will help maintain high standards for reliability, security, and scalability, enabling product engineering teams to build seamlessly on top of a powerful, resilient backend foundation.

What You'll Do

• Core Platform Architecture: Contribute to the design and implementation of highly scalable, distributed core services and backend platform components using TypeScript and modern cloud-native technologies.
• Orchestration & Messaging: Develop and maintain reliable asynchronous architectures, utilizing event streaming (Kafka) and complex workflow orchestration (Temporal) to power critical business logic.
• Platform Security Systems: Assist in the evolution and scaling of our enterprise-grade authentication and authorization frameworks, ensuring seamless and secure data access layers.
• End-to-End Data Engineering: Optimize and scale complex backend data platforms and document-based storage systems (MongoDB) to handle high-throughput workloads.
• Technical Standards: Adhere to and advocate for clean coding patterns, robust architectural standards, and engineering best practices across the backend organization.
• Cross-Functional Collaboration: Partner closely with Product, Security, and Core Infrastructure teams to align platform capabilities with product roadmaps and strategic company goals.

What You'll Bring

• 7+ years of software engineering experience with a strong, specialized focus on backend engineering, distributed systems, and core platform development.
• Strong proficiency with TypeScript alongside solid production experience within our modern ecosystem stack ( Temporal, Kafka, MongoDB, and AWS ).
• Startup DNA: Proven experience delivering high-impact technical solutions within fast-paced, high-growth Series B or Series C environments.
• Industry Domain Knowledge: A strong background in the B2B SaaS space, with a track record of building backend applications that scale alongside growing enterprise customer demands.
• System Design Experience: Demonstrated success contributing to complex data pipelines, identity/access systems, and high-availability core services.
• Clear Engineering Focus: A profile centered squarely on core backend application architecture rather than frontend/full-stack development or infrastructure-heavy/DevOps operations.
• Effective Communicator: A strong collaborator who can clearly explain technical concepts and work productively with both technical and non-technical stakeholders.
