Original job description

ABOUT US

Caddie Intelligence builds software for analytical testing laboratories and other regulated industries.

WHAT WE'RE BUILDING

Something meaningful, in an industry that quietly touches billions of lives and almost nobody thinks about. The work inside it is slow, manual and consequential and the decisions being made every day deserve to be faster, more consistent, and easier to stand behind.

THE ROLE: YOU WILL BUILD IT END TO END

One product, two homes: our cloud, and inside our customers' own buildings. You own everything that runs on a server, wherever that server is.

The engine at scale: containerised Python workers (FastAPI, NumPy, SciPy) that make the same decision on every machine, byte for byte

Instrument files: read the binary files laboratory instruments produce, and write Caddie's decisions back into them so the lab's own software still opens them and does the maths

New test methods: turn a new laboratory test into a working module with the founders, following our written playbook

The cloud: S3, SQS, ECS Fargate, KMS

The on-premise edition: the same engine and the same app running inside a customer's network with no internet. Containers, local Postgres and file storage, signed offline updates, Windows and Linux servers

The record: immutable storage, hash-chained audit events, ten-year retention, in both homes

Multi-tenancy: PostgreSQL row-level security, IAM, SSO

The self-serve layer: schema design, immutable versioning, approval workflows

The plumbing: Terraform or CDK, CI that blocks regressions, monitoring

WHAT YOU'LL NEED

Strong Python, including NumPy, and SQL well past CRUD

You care about exact numbers. You know why the same calculation can give different answers on two machines, and how to stop it

Comfortable taking apart a binary file format nobody documented

AWS deep enough to design it, not follow a tutorial

You have shipped software that runs on someone else's servers, not just your own cloud

You can design one system with two homes, where every cloud piece has a local twin and nobody maintains two codebases

Enough front-end ability to ship a screen yourself when it is faster than asking

You use AI tooling hard, and you are ruthless about reviewing what it writes (Cursor, Claude Code, Codex, etc.)

NICE TO HAVE

Signal processing, chromatography or other scientific data

Regulated software: audit trails, data integrity, validated systems

Docker, air-gapped installs, Windows Server

WHO YOU ARE

Critical thinker who pushes back
proactive, nobody is going to hand you a ticket
wants ownership of the schema, the server and the alarm that wakes you up
fast without being sloppy
ability to handle adversity
someone who has the desire to be great

NOT REQUIRED

A specific number of years. We care whether you can do the work, not how long you have been doing it

Any degree or higher education

WORKING HERE

A direct line to the founders. No waiting a week for a decision
Fast paced environment, team retreats, ability for your voice and ideas to be heard
You see the whole company, not a slice of it: commercial, technical and strategic
Access to the network behind us: investors, operators and advisors who have built and sold companies in this space
You grow as the company grows, and you will be able to point at the parts that are yours

Caddie is backed by ERA, the New York accelerator.

More about this job

Responsibilities

Build and maintain a Python-based analytical engine and related application for both AWS cloud and customer-hosted, offline environments, including instrument file processing and laboratory test modules. Own the system end to end, including infrastructure, data integrity and audit records, multi-tenancy, workflows, monitoring, and regression-preventing CI.

Requirements

Requires strong Python, NumPy, advanced SQL, deep AWS expertise, and experience shipping software on customer-owned servers; the role also calls for binary file analysis and ensuring calculations produce consistent results across machines. Candidates should be able to design a single system for cloud and on-premise deployment, contribute to frontend work when needed, and critically review AI-generated code; no specific years of experience or degree is required.
