Job Description

We build and operate a regulated digital health platform. Patients trust us with clinical data, identity documents and payment details, and our clinicians trust our systems to be correct. That makes application security a patient safety concern, not just a compliance one.

We are shipping quickly, adopting AI and agentic systems across clinical operations and patient-facing products, and running a lean security function that scales through engineering leverage rather than headcount. We need a senior engineer who can go deep on design and code, then bring the rest of the business along with them.

This is a hands-on individual contributor role with genuine influence over how the platform is built.

You will work within the Cyber Security function, collaborating directly with Engineering, Product, Clinical, Legal, and the executive team. Security at Numan is not a gatekeeping function - it scales through influence, credibility, and being useful early.


Responsibilities

  • Running threat modelling sessions with product and engineering teams on new features and architectural changes - STRIDE-based, with clinical safety, abuse, and business-logic threats kept in mind alongside the technical ones.
  • Owning and evolving our Secure by Design process: self-evaluation screening, secure design review, and the threat modelling pathway, including our use of automated tooling against technical artefacts.
  • Turning threat models into tracked, prioritised controls that engineering teams actually implement.
  • Pushing design decisions upstream so the cheap fix is designed in rather than the expensive one retrofitted.
  • Assessing and securing AI systems in production: LLM-backed features, retrieval pipelines, agentic workflows, tool-calling integrations, and the MCP and API surfaces that connect them.
  • Building practical threat models and controls for agent-specific failure modes - prompt injection, tool misuse, excessive agency, data exfiltration through context, unsafe autonomy, and supply chain risk in model and plugin ecosystems.
  • Performing automated application and API penetration testing against our own products - web, mobile backends, cloud-native services on GCP, internal tooling, and AI features.
  • Leading penetration engagements with third parties and working on the fix with engineering.
  • Chaining findings into realistic attack paths and demonstrating impact, rather than delivering a list of scanner output.
  • Embedding security into our pipelines: SAST, SCA, secrets detection, IaC scanning, container and dependency hygiene - tuned so signal beats noise and engineers trust the gates.
  • Working with platform and engineering to raise baseline standards: authentication and authorisation patterns, secrets management, tenancy isolation, and logging and detection coverage.
  • Actively participating in the security community - OWASP chapters or projects, local meetups, CTFs, research groups - and publishing research, write-ups, or blog posts under your own name.

Requirements

  • Brings substantial hands-on application security experience in a product engineering environment, at senior level.
  • Has demonstrable threat modelling practice - not just familiarity with the theory.
  • Has practical offensive skills against modern web and API stacks, with an appropriate certification or equivalent demonstrable experience (OSCP, OSWE, CREST, Burp Suite Certified Practitioner or similar).
  • Is comfortable reading and reasoning about code in at least one language used in production systems, and can review a pull request meaningfully.
  • Has working knowledge of cloud-native architecture and its security model - ideally GCP, but AWS or Azure experience transfers.
  • Has experience integrating security tooling into CI/CD, and the scars to know what makes engineers ignore it.
  • Has a track record of shipping security improvements through other teams.
  • Has experience securing AI or agentic systems in production.
  • Has hands-on experience securing Kubernetes environments and managing cloud security posture using CNAPP and CSPM solutions, with a primary focus on GCP but AWS and Azure experience is translatable.

It's a bonus if you have

  • Regulated environment experience - healthcare, fintech, or similar - and comfort with frameworks such as ISO 27001 without treating compliance as the goal.
  • Detection engineering or incident response exposure for incidents related to application attacks.
  • An existing community footprint: talks, published research, maintained projects.

Company Benefits

  • A competitive base salary
  • 25 days holiday + bank holidays
  • A flexible working environment that allows you to make the biggest impact
  • A chance to help build a category-defining company that’s making a real difference in people’s lives
  • Continuous learning - Books, online subscriptions and budget for workshops and conferences.
  • Annual Learnerbly budget
  • Work in a dog friendly office
  • Health Insurance with HealthShield. This is a health cash plan paid for by the company. It also includes 24/7 counselling support, EAP programme, 24/7 GP access, access to wellbeing app Thrive and further discounts on fashion, holidays, entertainment, car hire, health and beauty and your weekly shop via the reward platform MyPerks.
  • Pension contribution: 5% employee 3% employer contribution
  • Cycle to work scheme and secure cycle area to keep your bike safe
  • Discount to our Numan products (also for family and friends)
  • Free eye test

Job Description

Starling is the UK’s first and leading digital bank on a mission to fix banking! Our vision is fast technology, fair service, and honest values. All at the tap of a phone, all the time.

Starling is the UK’s first and leading digital bank on a mission to fix banking! We built a new kind of bank because we knew technology had the power to help people save, spend and manage their money in a new and transformative way.

We’re a fully licensed UK bank with the culture and spirit of a fast-moving, disruptive tech company. We’re a bank, but better: fairer, easier to use and designed to demystify money for everyone. We employ more than 3,000 people across our London, Southampton, Cardiff and Manchester offices.

Our technologists are at the very heart of Starling and enjoy working in a fast-paced environment that is all about building things, creating new stuff, and disruptive technology that keeps us on the cutting edge of fintech. We operate a flat structure to empower you to make decisions regardless of what your primary responsibilities may be, innovation and collaboration will be at the core of everything you do. Help is never far away in our open culture, you will find support in your team and from across the business, we are in this together!

The way to thrive and shine within Starling is to be a self-driven individual and be able to take full ownership of everything around you: From building things, designing, discovering, to sharing knowledge with your colleagues and making sure all processes are efficient and productive to deliver the best possible results for our customers. Our purpose is underpinned by five Starling values: Listen, Keep It Simple, Do The Right Thing, Own It, and Aim For Greatness.

Hybrid Working

We have a Hybrid approach to working here at Starling - our preference is that you're located within a commutable distance of one of our offices so that we're able to interact and collaborate in person. We don't like to mandate how much you visit the office and work from home, that's to be agreed upon between you and your manager.

Our Data Environment

Our Data teams are excited about the value of data within the business, powers our product decisions to improve things for our customers and enhance effective and agile decision making, regardless of what their primary tech stack may be. Hear from the team in our latest blogs or our case studies with Women in Tech.

We are looking for talented data professionals at all levels to join the team. We value people being engaged and caring about customers, caring about the code they write and the contribution they make to Starling. People with a broad ability to apply themselves to a multitude of problems and challenges, who can work across teams do great things here at Starling, to continue changing banking for good.

Requirements

We have built our entire banking platform in house and mostly in Java. We are looking for people who want to work on building the tooling that is used by our engineers on a daily basis.

We are looking for people who are truly full stack, and are as comfortable polishing their javascript front end as they are debugging the innards of their java applications database interactions, or standing up infrastructure with terraform. We are looking for people who can:

  • Design REST apis.
  • Code backend services, ideally using Java, or another other server side compiled language.
  • Develop modern front ends, ideally using React and Redux.
  • Get their code into the cloud and support it there, ideally on AWS.
  • Believe in clean coding, simple solutions, automated testing and continuous deployment.
  • Like to take ownership of a feature from the original idea through to live.
  • Think (like us) that a small number of empowered developers is the right way to deliver software.

Company Benefits

  • 33 days holiday (including flexible bank holidays)
  • An extra day’s holiday for your birthday
  • 16 hours paid volunteering time a year
  • Part-time and/or flexible hours available for most roles

  • Life insurance at 4x your salary
  • Hybrid/remote working
  • Private Medical Insurance with VitalityHealth including mental health support and cancer care. Partner benefits include discounts with Waitrose, Mr&Mrs Smith and Peloton
  • Generous family-friendly policies
  • Varied social groups set up and run by our employees
  • Perkbox membership giving access to retail discounts, a wellness platform for physical and mental health, and weekly free and boosted perks
  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

Interview Process

Interviewing is a two way process and we want you to have the time and opportunity to get to know us, as much as we are getting to know you! Our interviews are conversational and we want to get the best from you, so come with questions and be curious. In general you can expect the below, following a chat with one of our Talent Team:

  • Stage 1 - 30 mins with one of the team
  • Stage 2 - Take home challenge
  • Stage 3 - 90 mins technical interview with two team members
  • Stage 3 - 45 min final with an executive and a member of the people team
