Senior Software Engineer at Checkout.com:
Our solutions allow merchants to route dynamically a transaction to the best payment provider to optimise their conversion rate. Your main task will be to design and create or maintain micro-services within our infrastructure. Our product handles millions of transactions within a week. The API has its key part on it but the load is also on a multitude of other services.
You will work closely with our technical teams to learn about the possible technical bottle-necks. We have implemented different technologies such as Go (go-kit toolkit, gRPCâŚ), Kubernetes, AWS, PostgreSQL and many others. Your role would be to lead us to new technologies that our product can benefit from.
Our product handles financial data making uptime one of our key KPIs. We expect that you will be able to work on high-availability and technically challenging programs.
You will join a talented team of 10 engineers, Data Scientists and DevOps, that are tech-passionate, working closely with most of them. Our main goal is to ensure that we can contribute to your personal growth as an engineer.
Payments are often compared to a black-box. Merchants around the world have issues understanding how their performance is and what optimization can be done. Our team is focused on building the best payment performance tool there is. It allows merchants to better understand their online processes as well as offline payments.
We offer 2 products to our merchants:The first, named Telescope, allows us to analyse, understand and make recommendations to a merchant. It does not require any technical integration from them and works mainly through webhooks, pulling data from APIs or parsing exported files.
If you don't meet all the requirements but think you might still be right for the role, please apply anyway. We're always keen to speak to people who connect with our mission and values.

Key Responsibilities:
At Monzo weâre aiming to build the best current account in the world. We are always keen to hear from capable, creative engineers who want to help us accomplish that goal. We want our bank to be safe and secure for our customers, so security is very important to us
Security at Monzo
Monzoâs security team has a wide range of responsibilities, from infrastructure security to application security. As a bank, we are solving diverse, novel problems to ensure that our customers are safe and secure.
One of the guiding principles of security at Monzo is that security at the expense of user experience is a last resort. We aim to move mountains in the background such that we can build world-class features without compromising on security.
As a member of our security team you would be responsible for constantly improving the security of Monzo, and you would work closely with other teams to ensure that our systems are secure by design. Of course, security incidents can and do occur, and the security team is involved with many different types of incident response.
Our engineers have a variety of different backgrounds
We have several non-graduates; only some of us studied Computer Science; one of the team has a degree in Marketing; some of us have worked in huge companies; some have only ever worked in startups; others are former consultants. As long as you enjoy learning new things, weâd love to talk to you.
We encourage an open and transparent working environment
You can get involved in any aspect of the business you are interested in and, following Stripeâs example, all emails in the company are visible in an email archive. We regularly run hackathons in which people build things on our third party API and we contribute to open source software as much as possible. Weâve also made our product roadmap public and give sneak peeks of features in our community forum. Our blog is a good place to learn even more about what we do!You can get involved in any aspect of the business you are interested in and, following Stripeâs example, all emails in the company are visible in an email archive.

We offer competitive salaries based on skills and experience, which could be anywhere between ÂŁ40,000 - ÂŁ100,000 per year.
We care deeply about inclusive working practices and diverse teams. If youâd prefer to work part-time or as a job-share, weâll try our best to make this happen. Just let us know in your application so we can plan for it.

About Cuvva
Cuvva is a new kind of insurance thatâs fast, friendly, and flexible.
We get it - insurance doesnât sound exciting. But this isnât insurance as you know it. Itâs insurance the way it should be. Weâre putting the customer first and building products that solve real human needs.
We were the first company in the UK to sell hourly insurance, and the first to sell insurance through an app. Weâve sold over 1 million policies. Weâve written over 260,000 lines of code. And weâre a fast-growing team of over 70 talented people.
Why work for Cuvva?
Weâre shaping the future of insurance. So we donât cut corners. We try to do the right thing, even when that makes life more difficult for us.
Weâll speak up when we have an idea - but we know when to let go and get behind something else.
And weâre comfortable giving and receiving honest feedback, and trying new ways of doing things. Itâs the Cuvva way.
Weâre building a diverse team with different backgrounds, outlooks and experiences. So we give everyone a fair chance of getting a role at Cuvva. Even if you secretly donât love insurance. (Donât worry - we didnât either.)
And if you need any adjustments or support when youâre applying to Cuvva, no worries. Just let us know.
As well as a competitive salary (ÂŁ75-90k, dependent on experience) and equity based remuneration, benefits of working at Cuvva include:
Equality
Weâre committed to ensuring that everyone has a fair chance to join Cuvva, whatever your background. We will always treat your application in a fair and equal manner.
About the role
We're looking for a software engineer who has held senior positions in engineering teams within high-growth, high-scale startups, who will operate with a high level of autonomy, ensuring impeccable reliability and availability. You care deeply about building rock-solid infrastructure for the long term, with a track record of delivering solutions which support your team and your product.
You will develop Cuvva's core platform, abstracting the key processes required to sell insurance, delivering solutions that allow the team to develop strong and stable products, without having to spend time ensuring they get the basics right.
Aside from developing core platform services, we expect you will also become heavily involved with ops and security activities, contributing towards the maintenance of our servers, AWS account, etc.
"Core platform"
When we refer to the "core platform", we mean the services which underpin the processes of all insurance activities on our system.
For example, we expect one of these to be the "policy service", which might be responsible for ensuring compliant issuance of policies, coordinating mid-term adjustments, preventing overlapping policies (double insurance), etc.
Other services could include user authentication, risk & pricing calculation, handling the process of modifying user data in-line with any mid-term adjustment requirements.
All services we consider to be part of the core platform will have strict requirements around stability, data integrity and transactional safety. All functionality must fail safely and explicitly, for example using 2-phase commit processes or other similar techniques. This will also require a reasonable level of testing to validate this safety.
The perfect addition to our team will have:
We are a small team so it is important that the successful candidate is not only technically highly competent, but also a great cultural fit!
