Profile match
Arqit is a London cybersecurity company founded in 2017 that supplies symmetric key agreement software designed to resist quantum attack. Its product distributes rotating encryption keys to endpoints and cloud services without relying on the public key mathematics that quantum computers threaten. The company works with defence, telecommunications and financial customers preparing for post-quantum migration.

Join our growing team and become part of a close-knit, welcoming group of world-class innovators, who are passionate about building products that make a real difference.

Our team thrives on solving complex technical challenges and has a long history of delivering world-first cybersecurity solutions. With experience spanning Silicon Valley startups and large-scale multi-national corporations, our team offers an exceptional environment for mentoring, learning, and growth.

This spirit of innovation extends beyond our own walls: we maintain strong ties with Belfast's leading universities through collaborative research projects, and are now launching new initiatives in AI, networking, and encryption.

Our 100+ staff worldwide describe Arqit as providing a positive and inclusive working environment, where staff feel that managers care about the success and well-being of their teams, and individuals feel valued as employees.

As we continue to grow and innovate, we have a new opportunity for a software project manager to run a portfolio of software projects across our engineering teams. The work spans a range of technologies, with a particular focus on Python, Rust and Java/Kotlin. Some projects are AI-focused, so you'll need to be comfortable managing work where requirements are still forming and the technology is moving quickly.

You'll be the person who keeps projects on track, clear and delivered. You'll work closely with engineers, product, security, sales and pre-sales, and you'll be the one who turns a customer need and a set of product requirements into a workable plan that a team can deliver against.

What you'll be doing

  • Work with the product lead and engineering managers to plan, run and report on multiple concurrent software projects from kick-off to delivery.
  • Build and maintain project plans, timelines, dependencies, budgets and resourcing - and help the team manage through changes, delays and the inevitable curve-balls of product development.
  • Identify, log and manage risks, issues and dependencies, and escalate early.
  • Work with engineering leads to scope work, estimate effort and agree what gets done first.
  • Help the engineering team with accurate, low-impact metric gathering to identify where and how resources are used.
  • Manage the AI project pipeline: scoping experiments, setting success criteria, tracking model and data dependencies, and managing the move from prototype to production.
  • Ensure projects meet security and compliance requirements, including data classification, export control and customer security questionnaires.
  • Keep stakeholders informed with clear, honest status updates
  • Champion good delivery practice: definition of done, code review, testing, documentation and post-project reviews - in a rapidly-changing environment where AI forms an increasingly important tool for the development teams.
  • Support prioritisation across the portfolio and help leadership make trade-offs with real information.

What we're looking for

  • History of successful project or delivery management on software projects.
  • A working understanding of software development projects, and experience communicating positively and constructively with stakeholders including product and engineering management, software developers and testers, and customers.  You don't need to write code, but you need to understand what the engineers are telling you and ask the right questions.
  • Strong written and verbal communication, with the ability to explain technical trade-offs to non-technical audiences.
  • Proven ability to manage several projects at once, with competing priorities and multiple stakeholders.

Please note that ability to work in the UK without visa restrictions is ESSENTIAL

Useful to have (but not essential)

  • Experience managing AI or machine learning projects
  • Experience in cybersecurity, cryptography, defence, government or other regulated environments.
  • Familiarity with security and compliance frameworks, such as ISO 27001, Cyber Essentials or similar.
