Founding Engineer

About Splink
Splink is an AI supply chain technology company on a mission to modernize the infrastructure that powers the CPG industry. We work alongside leading distributors and brands – including P&G, Energizer and Hormel – to replace the legacy systems and manual workflows that have held this industry back for decades.

We're well-funded and moving fast to build the platform that will become the operating backbone of how billions of dollars move through the CPG supply chain.

What this role is about
We are looking for a Founding Full Stack Engineer to take ownership of our frontend, backend and data systems.

You'll work directly with the Founders as one of our earliest technical hires, with a direct line to the product decisions, business context, and architectural choices that will define how this platform gets built. This is an end-to-end role – you'll ship features across the frontend and backend, improve reliability and operational maturity, and make pragmatic architectural decisions that balance moving fast today with building something that scales tomorrow.

As the business grows and data volume increases significantly, you'll play a central role in shaping how we turn complex supply chain data into intelligence that changes how businesses run.

If you enjoy owning systems deeply, working across the stack, and turning complex data into powerful insights, this role offers the opportunity to have outsized impact in a small, rapidly growing company.

What you'll do
Drive full-stack development: Take end-to-end ownership of frontend and backend feature development, from data models and API design through user-facing experiences.
Make pragmatic architectural decisions: Evaluate the current frontend and backend architecture, understand its strengths and limitations, and guide incremental improvements that support higher data volume, faster iteration, and long-term flexibility without over-engineering.
Ship reliable, scalable systems: Improve system stability and performance by strengthening monitoring, alerting, and operational practices.
Build clear, usable user experiences: Maintain and extend intuitive, functional user interfaces that help customers understand complex sales and product data. Prioritize clarity, correctness, and usefulness over surface-level polish.
Collaborate closely in a small team: Work directly with our founders to translate priorities into shipped work. Communicate proactively and keep work unblocked and aligned.
Use modern tooling effectively: Leverage modern AI development tools, such as Claude and Cursor, to accelerate understanding of the codebase, reduce busywork, and improve productivity without sacrificing quality.

What we're looking for in our ideal candidate
5+ years of professional full-stack engineering experience, with substantial experience working across both frontend and backend systems
Strong experience shipping and owning production systems, with a backend-leaning skill set and meaningful frontend ownership
Experience designing and maintaining application programming interfaces and delivering end-to-end features in a cloud-based environment
Experience supporting real customers at real scale, including monitoring, debugging production issues, and improving system reliability over time
Comfort evaluating and evolving an existing codebase, including refactoring, performance improvements, and reducing operational risk
Strong written and verbal communication skills, especially in a small team
A high degree of ownership and self-direction, with the ability to take ambiguous problems and turn them into shipped, maintainable, and reliable solutions
Ability to write clean, testable code and to raise engineering quality through thoughtful code reviews
Care for building clear, usable user experiences that help people understand complex data
We do not expect you to have experience in every area listed. If this role excites you and you believe you can grow into it, we encourage you to apply.

Nice-to-have experience (not required!)
Exposure to Python-based services or data ingestion pipelines
Experience identifying and reducing operational risk in data-driven applications
Familiarity with relational data modeling tradeoffs in growing systems
Experience working in small, early-stage teams where priorities and responsibilities evolve quickly
Experience supporting customers or internal stakeholders directly when diagnosing production issues or data discrepancies
