Job Description

Loyyal Corporation

Loyyal is the Internet of Loyalty, on a mission to connect the largest loyalty programs across the world. Leveraging blockchain and smart contract technology, we provide a common ground for interoperability, accelerate the speed at which customers can earn and redeem value, give tools to programs to fine-tune incentivization, and smartly react to the varied interests and behaviors of customers.

By joining the Loyyal team, you are entering the cutting edge and rapid-changing world of blockchain technology, working collaboratively with a close-knit team to connect the world’s largest loyalty programs. As a member of a Loyyal, you will receive an equity share and market rate salary, as well as gym coverage, company adventures, global travel, and the freedom to have ownership and direction over your work. Of course, medical and 401k benefits too.


We’re solving challenging technical problems including observability, reliability and performance of distributed networks, distributed identity management and transaction synchronization across disparate platforms. We’re looking for enthusiastic and talented engineers to join our tight-knit team to help us tackle the hard problems at the frontiers of distributed systems.

When you wake up you may have unread messages of inspiration from our early rising CEO. You can glance at them and make a mental note to revisit them in normal human hours since asynchronous communication is encouraged. You’ll arrive at the office and nod to yourself about the modern facilities and say something like “this sure beats that literal garage I worked in that one time.”

At your desk you’ll quickly craft (or remind yourself of) your objectives for the day using asynchronous goal tracking tools. Then you’ll get straight to work. At Loyyal you own your time and push forward to achieve the goals of the company that are most important at the time. Today you could do any of the following:

- performance test a blockchain;
- improve the readability of Go code;
- hire more engineers;
- fix a Kafka / Zookeeper configuration issue;
- design a distributed identity management system;
- improve production support of the Loyyal platform;
- improve observability of a distributed system with log aggregation, alerts,
metrics, and traces;
- migrate a monolith to microservice architecture in Go;
- and much more!

Whatever you’re doing, chances are you’re learning something new and expanding your skill set.

During the day you’ll pause every now and then to make a comment about how floral tracksuits are fresh or to share your very good idea for a new episode of Black Mirror. At the end of every day you’ll have pushed forward the goals of the company in a concrete way. What’s more you’ll have made Loyyal’s vision of revolutionizing the loyalty industry by reducing barriers to entry and enabling novel functionality that much brighter and closer.


- 5+ years of experience in software engineering
- 2+ years of experience in and passion for Go
- You have familiarity with and passion for blockchain technology
- Specific working knowledge/expertise in Kafka/Zookeeper
- You write high quality, well tested code to meet the needs of your customers

- You’ve worked in a startup environment previously
- Up to 10% travel may be required
