About Jet’s Internal Engine
We’re building a new kind of company, and we’re building it from the inside out. For us this means that investing in hiring, developing, and retaining the brightest minds in the world is a top priority. Everything we do is grounded in three simple values: trust, transparency, and fairness.

About the Job
We are looking for exceptional back-end developers to help us build a world-class e-commerce platform. The Jet marketplace is powered by a real-time and dynamic pricing engine. We handle hundreds of millions of events per day that affect prices as customers shop. The Jet Pricing Engine is a set of sophisticated, scalable systems that are required to be low latency, high throughput, fault tolerant and highly available. The platform is an event-driven (event-sourced) system built largely in .NET and designed to run on Azure. The Dublin pricing team is an extension of our US team, which is responsible for generating all of Jet.com’s prices. We're looking for talented Software Engineers at all levels who get excited about working on distributed systems with huge business impact.
Jet’s pricing platform is built using a message-orientated, event-sourced microservice architecture, developed in F#. It leverages a mixture of proprietary and open-source tech such as Microsoft Azure, Redis, DocumentDb, Kafka, Event Store, TFS, Jenkins, and Nomad.
Some key factors of the Jet.com Pricing Team
Distributed systems: We build distributed architectures supported by Jet’s microservice and event sourcing platform. We build for scale, we build for 100 million messages/day.
Optimization: We deal with classic combinatorial optimization computer science problems that require constant research and optimization.
Platform-centric design: We look for patterns in everything we build and invest in reuse of functionality where appropriate.
Autonomy: The business might know what problems it wants to solve, but not how to solve them. We have free range to decide how we approach these challenges. We choose whatever tool or technology best fits the job.
Back-end focus with full-stack considerations: The pricing platform is a Tier 1 platform for an e-commerce site. We have:
- World-class deployment and operations
- Internal portals and APIs to interface with other Jet.com platforms
- Internal bespoke tooling
The individual will be someone with the following traits:
- .NET experience
- Solid understanding of large-scale, cloud-based distributed systems
- Uptime operational management and testing experience
- Experience with event-driven systems
- Strong drive and ownership over systems you're responsible for

Cookies we use and why we use them
- Essential cookies
Essential cookies are technical cookies that are required for the operation of our sites. Without essential cookies our sites can’t operate properly. Essential cookies include, for example, cookies that enable you to log into secure areas.
- Performance cookies
Performance cookies allow us to recognise and count the number of visitors to our sites and to see how visitors move around them. This helps us to improve the way our sites work by enabling us to tailor our sites to the way visitors use them. The information we collect from performance cookies is aggregated which means that we cannot directly identify you from it.
- Experience cookies
Experience cookies allow our sites to remember the choices you make. Our sites use experience cookies to provide you with enhanced and personalised features. For example, we use information collected through what are known as “web-analytic” cookies to compare the choices you make to those of our other users so that we can learn from those choices. Information collected by experience cookies cannot track your browsing activity when you leave our sites to browse other sites.
- Marketing cookies
Marketing cookies record your visits to our sites, the pages you have visited and the links you have followed.

Why are we allowed to collect your information?
The reason depends on the particular activity we use your Information for. During the recruitment process, we will collect your Information if one of the following applies:
- We need to use your Information to enable us to run our business successfully (the law calls it “legitimate interests”). This includes recruitment and hiring processes.
- We can only do this if we can show that there is little or no risk to you or your personal information rights (see “Your Rights”)
- We believe that our use of your personal information for recruiting purposes creates little or no risk to you or your rights but we want to be sure that you are happy for us to do it, so we will always ensure that we put you and your interests first.
- We also make it easy for you to exercise your right to ask us to stop processing your application at any time– simply contact us at the address provided in the Your Rights section.
- We need to use your information to comply with a law which we are subject to or we are legally obligated to do so. Where the law tells us that we need to use certain information, then we are allowed to do so, as long as we only use it for that purpose.
- You have specifically given us your permission (the law calls it “consent”). Where we need your consent to use your personal information for a particular purpose, we must be able to show that the consent is:
- Specific – we have to tell you exactly what activity your consent covers.
- Informed – we have to provide you with clear details of what you are consenting to.
- Freely given – you must have a genuine choice; for example, we couldn’t say “by registering for our free Wi-Fi, you consent to us sending you marketing emails” because that would prevent you from using the Wi-Fi service if you chose not to consent to marketing emails.
- Unambiguous – this means that you must have clearly indicated your wishes by confirming your agreement to a statement (e.g. by ticking a box) or taking some positive action to show that you intended to give your consent.
We will need your consent for the following activities – we will always make it clear at the time:
- Placing cookies on your device to find out how you use our websites so we can personalise what you see by tailoring advertisements and notifications to the things you are interested in
- Using the location tracking function on your mobile device to enable location based services and advertising
- Certain situations where you share sensitive Information about yourself, such as your health
Who we share the information with
We may share your information collected through cookies with advertisers and adverting networks so that we or they can show you relevant and interesting ads on and off our services. However, we do not share information that personally identifies you (personally identifiable information is information like name or email address that can by itself be used to contact you or identifies who you are) with advertising, measurement or analytics partners unless you give us permission. We may provide these partners with information about the reach and effectiveness of their advertising without providing information that personally identifies you, or if we have aggregated the information so that it does not personally identify you. For example, we may tell an advertiser how its ads performed (e.g. 500 men aged under 30 have clicked on their ad on any given day).
Processing by third parties
In order to carry out the steps set out above we may send your personal information outside of the European Economic Area and, if necessary, across international borders. The data protection laws in these countries may not be as comprehensive as in the European Economic Area. However, we have taken appropriate steps to make sure the same level of protection for the processing carried out in these countries as within the European Economic Area. Any details you provide may be electronically sent to the US to our parent company Walmart Inc., which helps us in running our websites. However, any such information will be dealt with in accordance with the Irish Data Protection Acts 1988 and 2003.
Storage of data
We will not store your personal information for any longer than we need to. However, we may be obliged by law to store your communications and personal information including activity logs and we may need to show details of these to government or authorised officials upon request. Like many websites, we use log files to monitor the effectiveness of our online marketing programmes.
