SPRX is hiring a Senior Software Engineer to help lead technical development on our AI-powered tax credit platform. We automate R&D credits, 179D energy deductions, and cost segregation studies for accounting firms and their clients.
About the role
You'll be a technical leader on our small engineering team, driving architecture decisions and mentoring other engineers. We're at a stage where the systems we build now will define how we scale—you'll have significant influence over that foundation.
What you'll do
Own the design and implementation of core platform features, from complex tax calculation engines to document processing pipelines. Make architectural decisions that balance shipping speed with long-term maintainability. Mentor engineers on the team and raise the bar for code quality and technical practices. Partner with product and customer success to scope technical solutions for new product lines. Improve our infrastructure, tooling, and developer experience as we grow.
Our stack
TypeScript end-to-end. Serverless architecture on AWS using SST. PostgreSQL with Drizzle ORM. RAG pipelines with Pinecone and LLM integrations throughout the product. We're pragmatic about technology—we care more about solving problems well than adhering to any particular dogma.
What we're looking for
5+ years of professional software engineering experience with meaningful time spent on complex systems. Deep experience with TypeScript/Node or transferable backend expertise. Strong opinions on system design, data modeling, and API architecture—and the communication skills to advocate for them. Track record of shipping features end-to-end and owning outcomes, not just code. You've helped other engineers grow, whether through code review, pairing, or technical leadership.
Nice to have
Experience with serverless or event-driven architectures at scale. Background building AI-powered features or working with LLMs in production. Familiarity with fintech, tax, or domains with intricate business logic and compliance requirements.
Compensation
$150k–$180k base salary plus equity.
