v2.0 Plato Engineering Career Ladders

Add your Career Ladders

Follow the 4 steps on this page to add/update public engineering career ladders and rubrics.
📌 IMPORTANT: To add your company’s public career ladder go to to submit a request. Once you’ve been granted Editor access, you will be able to add/update your company’s career ladder and rubric details. To prevent people from accidentally modifying others’ rubrics, only the person that added a new company ladder can go back and update it. If someone wants to edit a ladder they didn’t add, they’ll need to create a new ladder, and the existing one will need to be removed by the Plato team.

STEP 1. Add/Update company name and logo
Type the name of a company you want to create/update a career ladder for. If the company doesn’t show up in the company list, click ‘Add new company’ to add it to the list. If the company already exists, you can update the name and logo from here.

To add a logo, find a sharp JPG or PNG logo mark that is no larger than 450x260 in size, and drag and drop it into the corresponding cell or click the plus sign (+) and select it to upload it to your computer.

Level 1 engineers are at the start of their software engineering career. They’re working on well-defined tasks and are supported by the
team when stuck. They’re expected to ask lots of questions! As someone progresses toward Level 2 they should start to gain
confidence to pick up larger or less well-defined tasks with less required support.
Level 2 defines engineers who have learned the ropes, and are building the foundation to being solid individual contributors at Monzo.

Level 2 engineers are focussed on tasks assigned to them within their team, typically working with the support of other engineers to
reliably deliver these*.
We expect all Level 1 and Level 2 engineers at Monzo to show positive trajectory towards Level 3, and generally expect people to
progress from 2A to 3A within the course of 1-2 years at Monzo.

* Many squads at Monzo have fewer mobile engineers than other disciplines. Because of this, we expect mobile engineers to be able to
work independently in a squad from level 2c+.
Level 3 defines a solid individual contributor at Monzo, able to take on any technical problem related to their discipline or domain
confidently, and can clearly articulate how they’re working with others to help their team reach its goals. While we don’t expect any
engineer to work alone, Level 3 engineers are highly independently capable, and can lead on the design and implementation of a
feature or project. A Level 3 engineer not only delivers their own work, but also demonstrates the ability to bring up others around
them, for example through activities such as onboarding engineers into their team, or mentoring less experienced engineers working
with them. They’re engaged in the challenges, opportunities and risks faced by their squad, collective and discipline – taking part in
the initiatives where they’re best placed to help.
Our expectation is that all Monzo engineers are capable of reaching Level 3 within an appropriate timescale (see previous levels), but
they may not wish to take on additional responsibilities beyond this level, and that’s OK. Progression through level 3 to level 4 would
usually take up to 2 years experience, as a guide.
The scope and impact of a Level 4 engineer is typically felt at the team or domain level, with their influence beginning to spread wider across the business. It should be clear to see how a Level 4 engineer has contributed to a team achieving their goals for a quarter. The engineer brings distinct individual strengths, is self-aware of what these are, and are impactful through these.

In the past, progression to Level 4 focused heavily on leadership abilities. We’re now keen to recognise that impact at this scale can
be made in various ways (including by more generalist engineers), and that there are different ‘shapes’ of engineer at Level 4.

Depending on the individual situation, someone may skew more heavily towards certain behaviours and technical skills than others.
At one end of the continuum we have the tech lead, who excels at leading engineering in their team, effectively working with other disciplines such as product and design, or stakeholders such as finance and data analysts. Whilst they may be involved in running rituals, their impact is felt more around the engineering culture they foster through their work: tech leads cultivate the design of performant systems that scale and meet customer needs, encouraging and supporting their team to build software that is high quality and tested sufficiently. It’s important to note that some engineers may wear the tech lead hat before they reach Level 4, but not yet be meeting the level expectations in other ways; L4 and tech lead are not synonymous.
The other end of the scale has the domain expert, who is a collective or company wide subject matter expert in one or more areas of our platform, whether that’s a set of complex services or problems, such as Mastercard, or a particular technology such as Kafka. The domain expert drives technology forward for Monzo, and is typically the person to lead on systems design in that area, sharing proposals to level up others with their work.
In between will be people who are technically competent, excellent team members and highly productive but none of whom are a specific 'expert' in a particular thing or want to be a tech lead

Level 4 is a challenging step up from Level 3, and with it comes new responsibilities and expectations. Not every engineer will be capable of, or want to reach Level 4, but Monzo will always need engineers at this level and there will be opportunities to progress to this point should someone be willing and able. To progress through this level will likely take 2-3 years.
Staff and Senior Staff are senior leadership “Director Level” roles within Monzo. The engineer should be highly confident in the role
that they can personally play to be instrumental in helping Monzo achieve our collective and business goals. They do this by focusing
on high impact, high value work which likely involves our largest and most ambiguous problems, and by breaking down large
long-term projects and mobilising teams to deliver them.
As an engineer they’re a technical authority at Monzo, with influence and respect across multiple squads, disciplines and projects.
They proactively drive cross-team initiatives, championing our engineering principles and guiding others through pragmatic technical
choices and trade-offs. They actively help lead engineering technology strategy for their Collective or Discipline, not only in the
present, but for the future.
Progression to Level 5 will be possible for many engineers at Monzo, but the opportunities to do so will be more limited, taking into
account their discipline and area of the company
As a Level 6 engineer an engineer will be leading on technical initiatives which directly address Monzo’s most important needs,
beyond a single Collective or Discipline. To do this, they’ll be setting high level vision and strategy, and directly using their engineering
knowledge and abilities to create solutions to our most challenging problems.
They’re respected by both the wider Monzo engineering community, and the industry at large, because their past impact speaks for
itself, both from work where they’ve been involved directly, and through appropriately working through others.
To move to and progress through Level 6 they’ll be on an individual journey and their progression and goals will be very bespoke. These will be agreed with their line manager and other senior leaders around the business. There will be a difference between an
engineer being a general L6, and one who is doing a very specific job (e.g. VP Architecture). Progression to L6 is not a given, and
depends on having a specialism or unique skill that is critical to the company.
