About The Engineering TeamAs a Software Developer - Applied AI you'll be joining a world-class engineering team capable of delivering award-winning products at industry leading levels of speed and quality.
We are looking for someone that shares our desire to make an impact and our belief that high quality-standards contribute to our ability to move fast. As relentless learners, we are constantly looking for ways to hone our craft and share our knowledge. We value software design fundamentals and the deep thinking required to ensure we’ll continue to move fast in the future. And fast we are - we ship many of our services through to production many times per day!
As a Software Developer - Applied AI on our Tax Intelligence team, you'll be joining a world-class engineering team building the agentic and retrieval-augmented generation (RAG) systems that power Blue J's leading tax work platform.
We value software design fundamentals combined with data-driven experimentation that allows us to deliver value in quick increments. We deploy many of our services through to production many times per day. We pair that with an experimental mindset: we use data to find problems, form hypotheses, and test them in short, iterative feedback loops, both before and after we ship.
About the RoleWe are looking for a seasoned software developer capable of delivering significant impact directly and indirectly through peer mentorship. You will be responsible for the design and implementation of critical parts of the agentic and RAG operating system behind our tax work platform.
We're looking for people with a range of profiles, and you may see yourself in one or more of these:
Platform foundations:
distributed systems, reliability, fault recovery, and strong data models and contracts
Agentic and RAG platform:
the retrieval, orchestration, and agent layers built on top of those foundations
Product experience:
full-stack React features that put those capabilities in the hands of tax professionals
Evaluation and data-driven decisions:
synthetic evals before release and mining of user data after release, turned into actionable insights that drive rapid iteration
What You'll be Doing
Challenging yourself to design, plan, and deliver new agentic and RAG capabilities, platform foundations, and product features
A substantial amount of coding, primarily in TypeScript, while leading other developers to help you deliver mission critical projects in an iterative and incremental fashion, regularly unlocking customer value along the way
Using data to identify problems, forming hypotheses, and validating them through short, iterative feedback loops both before and after release
Building and evolving a feedback loop that shows the impact of what we ship and guides where we focus next
Coaching developers in the craft of writing beautiful code covered by well written automated tests while nurturing the long-term health of the systems we work on
Giving impactful feedback in an empathetic manner to those around you
Helping elevate our engineering standards, tools, and practices
Here is a sample of recent initiatives shipped by our team:
Developing the agentic and RAG layers that deliver high-quality, precise research and draft deliverables while keeping latency and cost down
Designing the data model and contracts for a two-way, interactive experience between the user and the platform
Building durable execution and fault recovery into our distributed systems
Extending our MCP server
Building the evaluation tooling that tells us whether what we ship is working
Delivering full-stack tax work features in React
Your Skills and Experience
You have 8+ years of demonstrable software development experience with a minimum of 2 years experience working with TypeScript
Hands-on experience building production systems involving LLM APIs, such as RAG pipelines or agentic workflows, using frameworks like LangChain, LangGraph, or Deep Agents
Deep expertise in at least one of: distributed systems and reliability, agentic and RAG systems, experimentation, or evaluation and data tooling
You've led significant initiatives involving multiple developers
Strong written and verbal communication skills
You approach your work with rigour and have an insatiable desire to learn
Technologies You Can Expect to Work With
Languages & Frameworks: TypeScript / Node.Js / Python / React / HTML / CSS
