Job Description
Hunter's product team is hiring a Backend Go developer! You'll become one of the key team members responsible for moving the data side of the Hunter application forward.
We’re a bootstrapped and sustainable product-focused company. We’ve set up a great work environment for our team, focusing on autonomy and growth. We take full advantage of the fact we’re entirely remote by focusing primarily on async communication and limiting the number of video meetings. Everyone in the team participates in discussions shaping the future of the product.
We love working as a small team and don't hire frequently. So this is a rare and exciting opportunity to join the team. You'll be part of the product team alongside Bastien (head of engineering), Bernardo (Backend Go developer), Mark (Ruby on Rails developer), Chris (Designer), François, and Antoine (co-founders).
About the role
At Hunter, we've been working from the start with one Go application (managing all our data) and one Ruby on Rails application (responding to users' requests). This setup has allowed us to be highly productive while our team stays small. We believe in always finding the most elegant way to build our product, and Go has been the ideal language to crawl, parse, and organize billions of public web pages.
As part of a small group within a young company, you will work on various projects over time, but you can expect that:
You'll work on our main Go codebase that gathers, processes, and provides all the data of hunter.io.
Within a few weeks, you'll become responsible for significant projects that will improve Hunter by building new critical features in our existing services. Over time, you'll help expand our product line.
You'll work with the rest of the product team to gradually increase the importance of NLP in our data pipelines.
You'll get a high level of autonomy in your work and help shape future development efforts.
You'll gather feedback from our Support team to find issues in our current system and improve it.
Hunter is a fully remote team, and this is a remote job. It is open to anyone located in Europe.
About you
You have multiple years of experience working with Backend Development. Ideally, you have experience in Go. If you don’t, you should be confident in your ability to pick up this new skill quickly.
You enjoy dealing with complex problems and finding elegant solutions.
You're confident you can have a high level of autonomy and enjoy making decisions for yourself.
You're excited to take ownership of projects, set directions, and make calls. You're able to communicate clearly with your colleagues.
You have experience in remote working. You're comfortable working primarily with asynchronous communication and don't need a lot of handholding or supervision.
About us
Salespeople, marketers, and recruiters use Hunter to reach out to the people that matter for their business. We index B2B data from millions of public web pages and make it convenient to explore with simple but powerful tools.
Hunter is the most popular solution to find professional email addresses. It is used by almost 3 million people and leading companies such as Google, Adobe, Microsoft, or IBM.
Hunter was founded in 2015 and is a self-funded company. We're a team of 11 peopleworking remotely from Europe, America, and Asia. Twice a year, the team meets in a company retreat in Europe.

Software Engineer BlueLabs Europe (Remote) €58,000 to €76,000 a year
April 2021
2 Applicants This Week
More Than 6 Months Old
This job posting is no longer available
Job Description
At BlueLabs we are building a next-generation sports betting platform focused on performance, reliability, modularity and automation. After a period of experimentation, we are now excited to see our technology powering the launch of BetFox, a new B2C operator in Ghana.
To ensure the continuous enhancement of our platform while scaling up operations and entering additional African countries, we are now looking to growing our team. As a result, two of our teams (i.e. Betting and Account) are now on the lookout for seasoned Software Engineers who want to join our distributed team and help us execute our vision.
The Team
The Account Team is responsible for the development and daily operations of the core services powering business-critical functions such as player account management and wallets. Other focus areas include, but are not limited to: responsible gaming, integration with third-party payment providers, integration with Mobile Network Operators, and player acquisition and retention programs with a focus on personalisation and automation.
The Betting Team is responsible for designing, developing, and operating all services relating to the lifecycle of bets in our sports betting platform. This stretches from bet placement to bet settlement, including advanced features such as an event- and player-based risk management, ability to build complex bets such as from outcomes with dependent probabilities, or continuous calculation of early settlement offers (cash out).
The services built by our teams are to be concurrently used by thousands of users and are expected to be able to handle hundreds of thousands of daily transactions in a timely manner.
Sub-second latency is welcomed but high throughput has higher priority in the Betting domain. The goal is building a sports betting platform where no bet is rejected due to lack of capacity in the system. Bet settlement is worth a special mention as the platform needs to be able to quickly evaluate hundreds of thousands of bets upon the resulting of an underlying sporting event.
Raw performance isn't everything. The team must also ensure that the platform can be easily adapted to be compliant with the different and ever-changing regulatory demands our industry is facing all over the world. The ultimate goal being to ensure a fair and safe sports betting experience to all our players.
We are building a microservice architecture based on event sourcing using Pulsar. Our services are written in Golang and use PostgreSQL as an operational database. We use SemaphoreCI to deploy our services to a GKE cluster, which is provisioned using Terraform.
A good candidate should have high standards for himself, a desire to build high-quality, well-tested, production-ready solutions and constantly improve his/her skills. We expect you to take ownership of some parts of the platform, be proactive over the entire development lifecycle and have the ability to work in a fast-paced environment. If this sounds scary, don’t worry - you won’t be alone in this. We value teamwork, trust, communication and a healthy working relationship, so you can always count on the team for support.
About You
You have good problem-solving skills, a tendency towards simple and effective solutions, and a “getting things done” mentality.
Analytical thinking, troubleshooting skills, attention to detail.
You are a reliable, trustworthy person that keeps their promises.
Interest in keeping yourself up to date and learning new technologies.
Product-oriented mindset and eagerness to take part in shaping the products we build.
Ability to work autonomously in a fully distributed team.
Good communication skills in verbal and written English.
Requirements
BS degree in Computer Science or similar technical field
1+ years of professional software development experience using Go
Experience building large-scale distributed systems, communicating asynchronously via message passing using RabbitMQ, Kafka or Pulsar
Deep understanding of DDD, CQRS, microservices architecture, and SQL/NoSQL data stores
Ability to write clean, efficient, maintainable, and well-tested code
Familiarity with test automation, cloud and containerization technologies, code instrumentation and CI/CD pipelines
Interest in taking full ownership of your services and managing them in a production environment including the troubleshooting of live incidents
Remote Work
We are hiring for talent, not for a specific location. You will find that members of our team are distributed all over Europe. Being a distributed team enables us to hire only the best, without being restricted to the talent pool available at a specific geographic location. However, to facilitate team communication and collaboration we currently require you to be located in Europe. You must also be able to travel to other European locations a few times a year for on-site meetings and workshops.
Compensation
The budgeted compensation range for this role is €58,000 to €76,000 annually, depending on your background and experience. As an independent contractor, you will be responsible for paying any taxes or applicable fees in your country of residence. In addition to that, we offer a number of perks to each of our team members as we truly believe in a healthy work-life balance and continuous learning.
