Why are we hiring for this now?Flatfile is a post-product market fit startup with rapidly accelerating growth, tons of runway, a lean, hungry, and sharp team playing for a huge outcome. We’re closing massive enterprise deals and evolving our platform quickly to scale with the growing demand. We have an ambitious roadmap ahead of us and need someone excited to lead the charge on many of these customer-impacting projects. From optimizing our event-driven system to scaling our industry-leading data engine, opportunities abound.
We want you to be a part of this.
Tech StackIn this role, you’ll use Node (Nest.js), Prisma, Postgres, Git, Flatfile’s homegrown data engine, and utilize AI for performance gains on a daily basis.

In this role, you will:

• Design and build backend services that power our scaling data exchange platform
• Provide leadership and guidance to internal team members on the implementation of architecture and system designs
• Developing and enhancing complex data structures to support enterprise use cases
• Own feature delivery from solution design to product operation and iteration
• Implement strategies to minimize data mapping errors, improve data accuracy, and establish performance benchmarks to ensure exceptional system performance 
• Improve usability through refined micro-interactions and interface design, as well as developing AI-powered features to assist users in managing, analyzing, and resolving data issues
• Share responsibility for responding to critical incidents as needed. Like all other teams, we are responsible for the reliability of the systems we build
• Contribute to, enable, and implement new AI models and features in partnership with our Applied AI team
• Fix bugs (of course)

Consider applying if you have:

• 10+ years experience in a production environment, with significant contributions to the design, architecture, and optimization of distributed systems
• Expertise in backend technologies, specifically Node, Postgres, and Redis
• Demonstrated capability to innovate and optimize at the system level
• Led all phases of software development, including ideation, product specification, prototyping, designing, and implementation. This role has a mix of both hands-on development as well as lead/architecture work
• A proven track record of raising the bar for technical standards, performance, reliability, and operational excellence

While many Engineering roles are similar, Flatfile’s Engineering roles are unique. With that in mind, you should pass on applying if:

• You don’t want to own decisions on how to approach technical problems and expect a lead or manager to make the final call. Our leads and managers provide feedback, but you will ship what you build and be accountable for it
• You refrain from engaging in or find it challenging to handle debates about the future state of products. We need someone who can have an opinion yet remain open-minded
• You prefer to avoid challenging the status quo or pushing the boundaries of technical possibilities, as this role demands continuous learning and adaptation to new technologies
• You’ve never worked in a fast-paced environment. We move quickly, and if you get frustrated when priorities change rapidly, we’re not the place for you
