FloQast•San Jose, CA

6h•Hybrid

About The Position

As a Staff Software Engineer, Core Platform, you will be a key technical leader driving the design, architecture, and evolution of FloQast’s foundational backend systems. You are a "systems thinker" who will own the development of 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 define the standards for reliability, security, and scalability, enabling product engineering teams to build seamlessly on top of a powerful, resilient backend foundation.

Requirements

10+ years of software engineering experience with a deep, specialized focus on "pure" backend engineering, distributed systems, and core platform development.
Expert-level proficiency with TypeScript alongside deep production experience within our modern ecosystem stack (Temporal, Kafka, MongoDB, and AWS).
Proven experience delivering high-impact architectural solutions within fast-paced, high-growth Series B or Series C environments.
A strong background in the B2B SaaS space, with a track record of building platforms that scale alongside growing enterprise customer demands.
Demonstrated success building complex, end-to-end data pipelines, identity/access systems, and high-availability core services from scratch.
A profile centered squarely on core backend application architecture rather than frontend/full-stack development or infrastructure-heavy/DevOps operations.
An effective collaborator who can easily break down complex architectural technical concepts and influence both technical and non-technical stakeholders.

Responsibilities

Lead the design and implementation of highly scalable, distributed core services and backend platform components using TypeScript and modern cloud-native technologies.
Architect and maintain reliable asynchronous architectures, utilizing event streaming (Kafka) and complex workflow orchestration (Temporal) to power critical business logic.
Own the evolution and scaling of our enterprise-grade authentication and authorization frameworks, ensuring seamless and secure data access layers.
Design, optimize, and scale complex backend data platforms and document-based storage systems (MongoDB) to handle high-throughput workloads.
Establish clean coding patterns, robust architectural standards, and best practices for the backend engineering organization while mentoring junior and senior engineers.
Partner closely with Product, Security, and Core Infrastructure teams to align platform capabilities with long-term product roadmaps and strategic company goals.
