Apple•Published 1 days ago•First seen 1 days ago

Summary

Imagine what you could do here. At Apple, new ideas have a way of becoming extraordinary products, services, and customer
experiences very quickly. You bring passion and dedication to your job and there's no telling what you could accomplish.
Apple is in search of an experienced Principal Software Engineer to join the Central Marketing's Marketing Enablement team in
London to drive technical architecture vision for its marketing products. This is a deeply hands-on, high-impact role: you will
work across portfolio of software products leading architecture discussions to decisions, establishing architecture and design
standards while contributing to software development.

Description

Our Principal Engineers are technical leaders who shape how software is built across a portfolio rather than within a single
product. You will own the cross-product architectural view understanding how our products fit together, where the boundaries
and dependencies sit, how information moves between them, and where duplication or fragility is accumulating and be able to
articulate this to stakeholders. From that view you will define a target architecture and a roadmap to reach it, setting the
agenda for consolidation, modernisation, and structural improvement across existing products, and sequencing that work so it
can be prioritised and delivered alongside ongoing commitments.
You will define and steward the architectural standards our products are built on, covering integration and interoperability,
security and data handling, operability, and the non-functional characteristics that determine whether a system holds up in
production. You will make those standards adoptable through reference implementations, templates, and working examples
rather than written rules alone. This is deliberately a hands-on role: you will prototype to de-risk significant decisions,
contribute production-quality code to shared foundations, and engage directly in the hardest technical problems, so your
recommendations are grounded in what actually works.
You will review solution designs and technical proposals early enough to change the outcome, establishing a repeatable
assurance process across all delivery, and advise on technology selection and significant investment decisions with an honest
assessment of long-term cost, flexibility, and constraints. You will lead architecture discussions with both technical and non-
technical audiences explaining choices in terms of cost, risk, and delivery impact, and driving each to a clear, documented
decision. Much of your impact will come through influence rather than authority. As a senior technical contributor, you will set
engineering standards, coach engineers on architectural thinking, and grow this capability across the organisation.

Responsibilities

Own and maintain the architectural view spanning our marketing products, covering integration points, data flows,
identity and access boundaries, shared services, and areas of architectural drift.
Design architecture for new products or major features and lead architecture discussions, and design reviews to a
decision with product and engineering teams driving alignment.
Drive technical excellence and contribute to growing engineering talent by setting design and engineering standards,
building reference implementations and shared components and mentoring engineers
Ensure our engineering foundations can support future growth by assessing them over time, identifying opportunities to
improve and working with product and engineering leadership to drive the implementation.

Minimum Qualifications

Extensive hands-on software engineering experience, with a demonstrable track record of designing and building
applications end to end, including several years in a principal engineer, architect, or equivalent senior technical role
Deep expertise in web application development, with genuine fluency in at least one of the programming languages -
Python, or Java and the ability to reason about and review the others, and hands-on experience with modern web
frameworks and libraries such as React, FastAPI, Flask, Django, SpringBoot, Hibernate
Strong grounding in relational data modelling (Postgres or equivalent) and in the design of APIs, service integrations,
and event-driven interfaces
Practical experience with externally-facing systems, including authentication and authorisation, content delivery, rate
limiting, auditability, and the associated security posture
Track record of leading architecture conversations to a decision, including with stakeholders holding competing priorities
and limited technical background

Preferred Qualifications

Experience in advertising or marketing technology domains, including ad trafficking, campaign management, and
creative asset management
Experience introducing an architecture practice — ADRs, review forums, published standards — into an organisation,
and driving genuine adoption rather than nominal compliance
Experience with platform and developer experience work that measurably reduced time to first release for other teams
