Principal Fullstack Engineer, Applied AI

About Aleph

Aleph is an AI-native platform for Financial Planning & Analysis (FP&A). We operate in an established software category with a multi-billion market but no clear winner. Our growth has come from product velocity and customer outcomes, not marketing spend, and the results speak for themselves.

Aleph was founded by Albert Gozzi and Santiago Perez De Rosso, two technical founders with backgrounds from Stanford and MIT and experience working at top-tier companies such as Google, Microsoft, and Bain & Company. We’re backed by top VCs (Bain Capital Ventures, Khosla Ventures, YC, Picus Capital), and work with customers like Webflow, Turo, Notion, Zapier, and many others.

What we’ve built so far is the most seamless way to centralize all of a company's financial data – think expenses from Quickbooks or Netsuite, pipeline forecasts from Salesforce – and bring it into the tools finance teams are already using. But the vision goes way beyond that: Aleph is AI-native at its core, automating reporting, variance analysis, and forecasting through intelligent agents. We’re building the always-on decision layer for modern businesses.

We’re moving fast, shipping constantly, leaning into AI to make the product smarter with every release, while also applying AI to how we sell, support and scale. Our churn is low, growth is strong, and the pace keeps accelerating.

We are hiring remotely across the Americas (United States, Canada, LATAM).

🔍 What we're looking for

We are seeking experienced software engineers to lead the development of Artificial Intelligence features across our web app & add-ins. You will work on determining how to best incorporate large language models (LLMs) and other AI technologies into our product. You will work closely with our product and design teams to explore the boundaries of what’s possible with AI, find innovative ways to apply the technology to Financial Planning & Analysis (FP&A), and ship features with a significant impact on our users' workflows.

👷 What you'll be doing

• Work hand-in-hand with leadership and other teammates to prioritize and execute on our product roadmap

• Own the development of new AI features end-to-end, from prototype to implementation in our core product

• Deliver robust, scalable, and well-tested code

• Help develop and establish best practices to lay the foundation for a high-performing technology team and its culture

• Collaborate with Design and Operation teams to keep making Aleph better every day

📝 What you have

• 12+ years of full-time software development experience, including React

• 5+ years of experience contributing to the system design or architecture (architecture, design patterns, reliability and scaling) of new or existing systems

• Product mindset—you're comfortable and eager to meet customers and develop an empathetic understanding of their problems to ensure we're building the right solutions

• Solid background in algorithms and data structures

• Experience with AI platforms and technologies, including generative models and LLMs

• Strong communication and collaboration skills, with the ability to work effectively with cross-functional teams and stakeholders

• Previous startup experience, or experience thriving in an unstructured environment

• Experience with a B2B SaaS product, analytics, or building tools for Finance teams

• Exposure and interest in Finance, with emphasis in FP&A

While this is a remote-first opportunity, we're focusing on candidates within the Americas to better align with our working hours as a team.
