We are hiring a Principal Engineer, Architecture. This is a senior individual contributor role for someone who is still happiest with their hands on the keyboard, and who thinks in systems while they build.

iQmetrix runs a large, long-lived platform: a retail management system that stores have depended on for years, a next-generation POS and commerce surface, an extension platform our partners build on, and a wide network of services underneath all of it. Keeping that coherent while it changes underneath us is real engineering work, not a diagramming exercise. It needs someone close enough to the code to see where the seams are pulling apart, and willing to do something about it.

You will work as a peer alongside our existing architects, sharing responsibility for stewarding technical direction across our solutions rather than dividing the org into territories. Architectural ownership at iQmetrix is distributed: teams own the decisions in their domain, write them down as ADRs, and bring them to our weekly architecture advisory forum for challenge and feedback. This role exists to improve how those decisions get made, recorded, and connected across teams — not to make them on everyone's behalf.

This is a role defined by contribution and influence rather than authority. You will spend your time close to the work: writing code, reviewing designs, pairing with teams on the decisions in front of them, and connecting problems that turn out to be the same problem in three different places.

The expectation is depth. You will go deep with a team or on a problem for a stretch at a time, long enough to be genuinely useful, rather than maintaining a thin presence everywhere re you focus is a conversation you will have regularly with your lead and with engineering leadership.

• You write code that ships. Not only reference implementations and prototypes — production work in real repositories, reviewed like anyone else's. Credibility in this role comes from having built the thing.
• You are accountable for architectural quality across the platform, and you support the teams who are accountable for delivering it.
• You work up and down the stack. Some of this work is deep in a service or an event pipeline; some of it is a customer's security review or an integration question raised by a delivery team.

The systems you will spend your time in:

• Luna — our next-generation POS: a Flutter application backed by an in-house design system and code generators it is built from.
• Luna.
  
  API — the .NET event-sourced backend behind it, built on Cosmos DB with bounded contexts for orders, tender, payments, repair, and cash management, and a layered architecture enforced in CI.
• Hub — our back-office solution,…
