Job Description

We are looking for a Team Lead to serve as the technical authority within our Product team. Think of this as a mini-CTO role: you will own architecture decisions, set technical direction, and drive the engineering culture for the team building Wintermute's client-facing and internal trading platforms. You will have significant autonomy to shape how we build, what technologies we adopt, and how we scale our systems to handle the data volumes and performance demands of a world-class trading operation. You'll lead a team of talented engineers while staying deeply hands-on with the codebase.


What you will work on:

  • Define and own the technical architecture for Wintermute's trading products, client-facing portals, and internal applications - making the key technology and design decisions that determine how these systems are built and scaled.
  • Lead and mentor a team of engineers across the full stack, setting standards for code quality, review processes, and engineering best practices.
  • Drive technical strategy and roadmap alongside product leadership, translating business requirements into robust, scalable technical solutions.
  • Architect systems that handle high data volumes, real-time streaming, and low-latency interactions - the kind of challenges you'd find on a trading platform processing millions of events per second.
  • Oversee frontend experience across the full customer lifecycle, from onboarding portals to real-time trading dashboards.
  • Work cross-functionally with product, marketing, trading, and backend engineering teams to ensure alignment and delivery.
  • Establish and evolve engineering processes - sprint planning, incident response, deployment pipelines - that let the team ship with confidence and speed.

Hard skills requirements:

  • 8+ years of software engineering experience, with at least 3 years in a technical leadership role (tech lead, engineering lead, or similar).
  • Proven track record of making architecture decisions for complex, data-intensive applications - ideally in trading platforms, financial services, or other high-throughput/low-latency environments.
  • Deep experience building and scaling real-time, high-data-volume systems (e.g., trading dashboards, live data feeds, streaming analytics, order management systems).
  • Strong command of the modern frontend stack: TypeScript, React, Node.js - and the ability to evaluate and adopt new technologies as needed.
  • Hands-on server-side experience: building and maintaining backend services, APIs, and data pipelines using languages such as Node.js, Python, Go, or similar.
  • Solid understanding of end-to-end system architecture: APIs, microservices, event-driven architectures, WebSockets, message queues, databases, and how frontend and backend systems work together in high-performance environments
  • Experience with infrastructure and DevOps fundamentals: CI/CD, cloud platforms, CDN, monitoring/observability, and deployment strategies.
  • Strong understanding of security best practices (OWASP, authentication/authorization patterns, secure data handling) - especially in a financial context.
  • Experience hiring, mentoring, and growing engineers - building a high-performing team, not just managing one.

Nice to have:

  • Experience at a trading firm, fintech, or any environment where milliseconds matter and data volumes are extreme.
  • Familiarity with algorithmic trading concepts and financial market infrastructure.
  • Experience with performance optimization at scale - profiling, caching strategies, efficient rendering of large datasets.
  • Experience with backend technologies beyond Node.js (Python, Go, Rust, or similar) for performance-critical services.

Write to us if you:

  • Love making hard technical decisions and seeing them pay off at scale.
  • Get energized by building high-performance systems that handle serious data volumes.
  • Want to shape the technical direction of a product team, not just execute on someone else's plan.
  • Are passionate about engineering culture - code quality, mentorship, and continuous improvement.
  • Are curious about algorithmic trading and financial markets.
  • Are determined, ambitious yet humble, willing to lead by example.
  • Thrive in a meritocratic environment where impact matters more than titles.
  • Prefer ownership over process - you'd rather build the right thing than follow a playbook.
  • Enjoy working in-person with your team (not fully remote).

Company Benefits

  • A unique opportunity to work on very interesting projects, get the level of responsibility and ownership that would be unlikely at any other project or trading firm
  • A unique opportunity to join one of the strongest and most successful CeFi teams globally
  • Great company culture: informal, non-hierarchical, ambitious, highly professional yet collaborative and entrepreneurial
  • A cool office in central London with a sci-fi touch
  • Although we are unable to accept fully remote candidates, we support significant flexibility in regards to working from home and working hours
  • On top of competitive base pay, we offer substantial performance based bonuses
  • We offer standard perks too, like pension, private health insurance and free food, but that’s probably not the right reason to join us
  • We offer UK work permits and help with relocation

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.

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.

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.

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
