Monzo; London; On-site; GBP 60,000 - 100,000

Job description

We’re on a mission to make money work for everyone.

We’re waving goodbye to the complicated and confusing ways of traditional banking.

With our hot coral cards and get-paid-early feature, combined with financial education on social media and our award-winning customer service, we have a long history of creating magical moments for our customers!

We’re not about selling products - we want to solve problems and change lives through Monzo ️

In Growth, we’re responsible for driving one of the most important company-level metrics: new user acquisition. We’re made up of small, autonomous, cross-functional squads and need to collaborate across disciplines to form and test hypotheses with the aim of unlocking value for customers as soon as possible. We focus on experimentation and using data to make decisions so that we can (in)validate these hypotheses as quickly as possible in order to identify impactful changes and double down on them.

You and your team will have the opportunity to have an impact on both what we build as well as how we build it.

We're looking for a growth-minded Senior Staff backend engineer with strong product experience.

You'll care about the impact your work has on our customers, and optimise for impact rather than the number of lines of code you output; progress over perfection.

As a Senior Staff Engineer:

A Senior Staff Engineer at Monzo is a technical (IC) leadership position. As a Senior Staff Engineer in the Growth collective at Monzo, you will:

• Partner with a Senior Engineering Manager supporting the collective and provide technical leadership across multiple squads and ~20 engineers.
• Work collaboratively with product, data and operational leaders to identify and execute on opportunities that further the organisation’s goals and strategy, bringing the right level of clarity, urgency and rigour as appropriate.
• Oscillate between contributing to high-level planning and strategy and organisational leadership and diving deep into the execution of problems and getting hands-on as necessary.
• Use your expert knowledge and experience to lead architectural discussions for complex systems in the collective. You’ll do this in order to arrive at solutions that are robust and optimal given the context.
• Keep a high bar for technical excellence in the collective, through your own work, highlighting the work of others and calling out when things haven’t quite met the bar.
• Pro-actively mentor, sponsor and up-level engineers.

What you’ll be using:

We rely heavily on the following tools and technologies, please note direct experience in these technologies is not required and our interview process can be completed in any language:

• Go to write our application code (there’s an excellent interactive Go tutorial here )
• AWS for most of our production infrastructure and GCP for most of our data infrastructure.
• Feast for storing our features along a variety of tools to train and deploy models.
• GPT and Vertex models for Large Language Model support.
• You have a track record guiding teams and stakeholders to prioritise things that drive important metrics and you take the lead in using data to make decisions. Bonus if you’ve partnered closely with Marketing stakeholders to do this.
• You have a track record of balancing speed of execution with technical excellence, delivering resilient systems for consumer products.
• You solve problems end-to-end, from client applications to backend infrastructure.
• You have technically led across 3-4 teams to solve complex optimisation problems.
• You’re comfortable working in a cross-functional team that deals with ambiguity and have experience helping your team and partner teams resolve that ambiguity.
• You have demonstrable experience working with stakeholders, especially non-technical stakeholders at the senior level.

The application journey has 4 key steps

Our interview process involves four main stages after an informal recruiter call:

• Initial Call
• System Design Interview
• Take home task or pair coding exercise
• Final interview including a behavioural and a leadership interview

This process should take around 3-4 weeks - your schedule is really important to us, so we promise to be as flexible as possible!

You will have the chance to speak to our recruitment team at various points during your process but if you do have any specific questions or want to talk through reasonable adjustments ahead of or during application please reach out to us at [e-mail]

We have some guidelines on using Artificial Intelligence (AI) to ace an application and interview at Monzo. You can read them here. Please also use that email to let us know if there's anything we can do to make your application process easier for you, because of disability, neurodiversity or any other personal reason.

One of our staff engineers has written a detailed blog on their experience through this process, for extra details, hints and tips please see here.

What’s in it for you
