Job Description

About the role

Oneiro builds DLX, a platform that helps financial institutions manage syndicated lending and loan administration.

We’re looking for a Senior Product Engineer to own meaningful product work from discovery through design, implementation, release, and production follow-up. You’ll work across the stack and collaborate closely with Product, Design, Engineering, and client-facing teams to turn real customer problems into pragmatic, reliable software.

This is a senior individual contributor role, scoped below Staff level. You’ll be expected to anchor project delivery, identify risks early, mentor others, and raise the quality bar within the team.

What you’ll do

  • Own features, workflows, and integrations from problem definition through to production.
  • Build clean, maintainable, well-tested software across the stack.
  • Turn ambiguous problems into clear technical plans and keep delivery moving.
  • Contribute to system and API design, data flows, reliability, performance, and security.
  • Work carefully with complex financial logic, calculations, dates, state transitions, and edge cases.
  • Define correctness invariants and design appropriate tests and controls.
  • Work closely with Product, Design, Engineering, and customers to understand real user needs.
  • Improve the tooling, documentation, testing, and systems you work with.
  • Support and mentor junior and mid-level engineers.
  • Develop deep expertise in syndicated lending and loan administration.

What we’re looking for

We look for candidates with strong analytical ability and evidence of excellence, whether demonstrated through academic achievement, professional work, or substantial projects, regardless of university or educational background.

  • 5+ years of professional software development experience, or equivalent practical experience.
  • Strong experience building and operating production software.
  • Expertise in TypeScript, JavaScript, Python, Java, or a similar production language.
  • Experience owning features from requirements through deployment and production support.
  • Confidence reasoning about mathematical models, financial calculations, assumptions, rounding, dates, state transitions, and edge cases.
  • Ability to independently validate complex financial logic and define correctness invariants.
  • A degree in Mathematics, Physics, Quantitative Finance, Computer Science, Engineering, or another highly quantitative discipline, or equivalent practical experience.
  • Good understanding of system design, APIs, data flows, automated testing, reliability, performance, and security.
  • Experience with cloud-native systems, integrations, distributed systems, or workflow-driven products.
  • Practical experience using AI development tools to improve engineering productivity or quality.
  • Strong communication skills and a product-minded approach.
  • Comfort working in a fast-moving environment where priorities and requirements can change.
  • Professional experience building software in banking, fintech, lending, payments, or another complex regulated domain.

Nice to have

  • Familiarity with corporate banking, syndicated loans, loan servicing, or financial operations.
  • Startup, scale-up, or founding experience, or experience in another high-ownership environment.
  • Experience integrating with third-party APIs or enterprise platforms.
  • Experience working in SOC 2, ISO 27001, GDPR, or similarly controlled environments.
  • Experience mentoring junior or mid-level engineers.

Location

The role is currently remote, with a preference for candidates based in or near Edinburgh or Glasgow. We’re exploring the possibility of opening an office in Scotland in the future, but these plans are not yet confirmed. We’ll be transparent as they develop.

Oneiro is committed to building a diverse and inclusive team and making our hiring process accessible to everyone.

Interview Process

Our process is designed to be practical, transparent, and useful for both sides.

  1. Hiring Manager Interview - 45 minutes
    A conversation about your experience, the role, the team, and what you’re looking for next.

  2. Take-home task
    A practical exercise based on the type of problems you may encounter at Oneiro.

  3. Technical Interview - 60 minutes
    A discussion about your technical approach, decisions, trade-offs, testing, and code quality.

  4. System Design Interview - 60 minutes
    A collaborative design exercise covering architecture, data flows, APIs, reliability, and trade-offs.

  5. Final Conversation with our CTO - 30 minutes
    A conversation about ways of working, values, Oneiro’s direction, and any remaining questions.

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

  • Access to initiatives like Cycle to Work, Salary Sacrificed Gym partnerships and Electric Vehicle (EV) leasing

Full details are available on our careers site

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
