Job Description

A Principal Engineer is the most senior technical role in manifesto's engineering team, providing leadership when it matters most: whether shaping a new client opportunity, designing complex architecture or resolving a critical live issue.

You will work across our client estate rather than being embedded in a single project, moving between platforms and codebases as the work demands. You will hold technical authority across our core stacks, .NET and Umbraco, PHP and Drupal, alongside the cloud infrastructure and hosting platforms that sit underneath them.

The role has three sides to it. You help shape technical solutions through discovery, technical qualification and solution design. You steer delivery on our most complex projects, setting the architectural direction and lifting the standard of the engineering around you. And you are the person who can drop into an unfamiliar codebase under pressure and diagnose what is actually happening, giving both our teams and our clients confidence at the moments that matter most.

We build digital products for charities, non-profits and membership and visitor organisations. Our clients are purpose-led, often working with constrained budgets, and the platforms we build carry donation journeys, supporter data and services people depend on. Technical decisions here have real consequences, and this role exists to make sure we get them right.

Responsibilities

  • Provide technical authority across our client estate, spanning multiple platforms, hosting environments and codebases.
  • Shape technical solutions for new business, from initial qualification through discovery to solution design and estimation.
  • Lead the architecture of our largest and most complex client projects.
  • Act as the senior technical escalation point for live incidents and complex problems, across multiple stacks.
  • Raise the standard of engineering across the department through mentorship, technical review and setting clear standards.
  • Build client confidence by representing us credibly with senior technical stakeholders.

You set and hold the technical direction on our most complex work

  • You define architecture that is appropriate to the client's budget, team and long-term maintenance capability, not to the most interesting technical solution available.
  • You uphold a clear software design philosophy and ensure teams deliver maintainable solutions.
  • You have a clear understanding of simplicity. You define solutions that are simple by design and challenge requirements that introduce unconsidered complexity.
  • You identify and challenge ineffective practices in delivery teams and in client organisations.
  • You delegate, and maintain clear separation from work that should be considered routine.
  • You make hosting, infrastructure and platform decisions with a clear view of cost, security and who will be responsible for what after launch.

You are the senior technical escalation point across the estate

  • You diagnose and resolve complex problems in codebases you did not write and may not have seen before.
  • You lead the technical response to significant incidents, establishing root cause and directing remediation.
  • You give clients and internal teams confidence at the point where things have gone wrong, through clear communication and visible control of the situation.
  • You identify the systemic causes behind recurring problems and drive the changes that stop them repeating.

You raise the standard of engineering across the department

  • You are an active and visible technical leader across the company.
  • You mentor lead and senior engineers, building capability rather than absorbing the hard work yourself.
  • You contribute to and uphold our engineering standards, technical governance and software development lifecycle.
  • You demonstrate your passion for keeping on top of current tools, standards and trends, including AI-assisted engineering practice.
  • You support marketing and new business with prototypes, thought leadership or presentations where it plays to your strengths.
  • You create learning within the team by specifying solutions that further our collective knowledge and give others opportunities to grow.

Professional knowledge and experience

  • Cross-stack technical depth. Genuine working expertise across more than one platform and language, specifically .NET and Umbraco alongside PHP and Drupal. Comfortable holding technical authority in both rather than being deep in one and passing in the other.
  • Architectural leadership. Expert in designing robust, scalable and secure architectures for content-managed platforms, integrations and modern web applications.
  • Cloud and infrastructure. Practical, hands-on experience with cloud platforms, particularly Azure, including CI/CD pipelines, infrastructure as code and managed hosting environments. Enough depth to make infrastructure decisions and resolve infrastructure problems with minimal support.
  • Diagnostic ability under pressure. Proven ability to enter an unfamiliar codebase, establish what is happening quickly, and lead resolution. This is a defining requirement of the role.
  • Pre-sales and technical discovery. Experience qualifying opportunities, running technical discovery, producing solution designs and estimating work before it is sold.
  • Software engineering principles. Mastery of clean code, testing practice, design patterns, security and accessibility standards.
  • Leadership and mentorship. Demonstrated experience developing lead and senior engineers, raising standards through others rather than personally absorbing the difficult work.
  • Commercial awareness. Understands that technical decisions carry margin, risk and maintenance consequences, and factors this into the solutions proposed.
  • Communication. Outstanding ability to explain complex technical concepts to non-technical stakeholders, and to hold client confidence when things are difficult.

Technical skills

Essential

  • Strong hands-on experience with content management platforms across more than one stack, specifically Umbraco and .NET, and Drupal and PHP
  • Practical cloud engineering experience, primarily Azure, including CI/CD pipelines, infrastructure as code and environment management
  • Experience across managed hosting platforms such as Azure, Acquia, Umbraco Cloud, WP Engine or Pantheon
  • API design and integration, REST and GraphQL, including third-party systems such as CRM, payment and marketing platforms
  • Security by design and DevSecOps practice, with particular awareness of handling supporter and donor data
  • Accessibility standards and practice, WCAG 2.2 and above
  • Version control, branching strategy and release management at scale across multiple codebases
  • Agile delivery practice, and how to make it work in a client services context

Desirable

  • Headless and decoupled CMS architecture
  • Authentication and identity, including OAuth and SSO
  • Search implementation, including AI-assisted and hybrid search
  • AI-assisted engineering practice, agentic tooling or AI-enabled development workflows
  • Experience of the charity, non-profit or membership sector and its particular constraints

Behaviours

  • You are the person others want on the call when something has gone wrong. You stay calm, establish facts quickly and communicate clearly under pressure.
  • You are pragmatic rather than purist. You choose the simplest approach that meets the need and challenge complexity that is not earning its place.
  • You proactively define and champion the long-term technical direction, ensuring it aligns with business goals and client reality.
  • You actively develop and empower other engineers, sharing knowledge and

Company Benefits

  • Some of our benefits include:
  • 30 days holiday + bank holidays
  • Life Assurance
  • 2 charity volunteer days for causes that you are passionate about
  • Working from home allowance
  • Share incentive plan
  • Maternity/Adoption Paid Leave =6 months, Paternity Paid Leave = 3 months
  • Cycle-to-work scheme

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 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.

  • 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
