Anyone looking for a job at a US scale-up company? GrayHair Software specializes in postal data processing and analysis for large US firms. They handle 25% of all US Postal data and track billions of pieces of mail every year for the top US banks and insurance providers. They already have four Spaniards in the development team and they are now looking for their fifth player, in the shape of a Java Developer, to carry on  growing. Are you ready? Keep on reading! 👀.

¿Qué harás?

Let's go back in time a little to see how they arrived to where they are today... Fasten your seatbelt and follow me ;)

The journey began in 2000 when GrayHair started as a mail tracking service. Just a few years later, by 2008, they managed to build a robust client list and added four additional services. However, in 2016 the company lost its founder… and later went on to pivot towards being a data-centric company. By 2020, the entire team was fully active and refocused on remote culture and tech transformation 💪. They learned from the past to grow into the future and became what they are today 🚀

GrayHair is a tech-company that specializes in processing and analyzing postal data for some of the largest companies in the United States. They handle 25% of all US Postal data and track billions of pieces of mail every single year for the top US banks and insurance providers. They process over 125 billion data points annually for their clients, providing increased visibility into vital processes across the organization to advance business goals.

Since 2000, they have become the leading consumer and provider of postal data, and their mission is to turn data into Business-Ready Intelligence. This intelligence enables company leaders to make informed decisions that can significantly improve essential business processes, such as marketing campaign effectiveness, fraud prevention, customer experience, and mail operations.

GrayHair is also undergoing a global technological transformation, redesigning all its services from scratch, taking advantage of cutting-edge technologies to provide even better services to its clients.

Business solutions currently offered by GrayHair include: Postal Optimization, Marketing Effectiveness, Customer Experience, Fraud Prevention, Mail Delivery Performance, and Address Data Quality.

What are they looking for?🧐

GrayHair´s wide product offering represents just a small percentage of their engineering. Most of what they do is backend driven, based in Java, and it doesn’t really involve user interface. They are currently in the middle of a migration over to AWS. They are looking at all the services they provide to clients from the ground up and re-doing them in AWS. There are 3 teams working in this area and it is where most of their development goes at the moment. They are using Spring Boot based microservices running on AWS ECS that are orchestrated via AWS Step Functions. While writing backend services is important, it is equally as important for teammates to have an understanding of how databases work and to be able to write SQL queries.

The ideal candidate they are looking for is someone who brings experience to the table, who’s hungry and will help them on their growth path. A team player, who likes to share and learn in equal parts, and whose goal is to continue growing alongside the team to find solutions for each new challenge that arises. Of course, you'll always be given the autonomy and freedom to do what you do best 😉

GrayHair Software is a 100% REMOTE company!

The headquarters are in Florida, USA. However, they are looking for someone to join the team they have based in Spain. Here they strongly believe in the advantages of working remotely and in work-life balance, so you might have colleagues from all over the country :)

They all work remotely, but they do a company offsite once a year, where all full-time employees are flown to the USA for a 3-day company retreat. Here are some pics from their most recent get-together in Florida:

What the FAQ?

You are only eligible for this position if you are a Spanish resident.

  1. There'll be an initial meeting with Robert, the Head of Development, so you can get to know each other and find out more about the company.
  2. The second phase would be a technical QA based on your experience and knowledge.
  3. This next step only applies to Mid/Senior developers: Solution Architect interview where you’ll get an abstract problem and will talk about how you would handle the solution. 
  4. Then comes the HR meeting. This meeting will be mainly to talk about employee benefits and to resolve  any questions you may still have.

NO. The team is spread over many different locations throughout Spain and the US.

They organize a fun company offsite once a year, where all full-time employees are flown to the USA for a 3-day company retreat.  Although attendance is not mandatory, I wouldn’t want to miss it if I were you!😜

Of course, they'll cover the cost of these trips for those who are overseas :)
