Swish is a world-class development studio whose teams have delivered products for Google, Microsoft, Kik, Nasdaq, Factset, and other major enterprises. The blockchain engineering team at Swish is looking for talented distributed systems engineers to optimize protocol transaction throughput and network reliability for blockchains in development.
Our mission is to bring the promise of a decentralized blockchain-based future to reality for clients.
As a systems engineer, you will work with our blockchain developers, protocol researchers and clients to implement and improve on a byzantine fault tolerant blockchain architecture based on the Tendermint consensus layer, by increasing the throughput, reliability and stability of the network. This role is ideal for engineers who have experience optimizing performance and robustness of distributed systems, and are excited to be working on the cutting edge of high-performance blockchain protocol development.
You might have experience as an Unix/Linux distributed systems engineer optimizing performance and reliability for large-scale cloud servers, and be relatively new to blockchain and distributed consensus protocols. Or you might be a blockchain engineer who is very familiar with distributed consensus protocols like delegated proof-of-stake, and newer to working on low-level performance optimizations. Experience with Tendermint is a huge plus.

We are also looking for: Strong communication skills. Experience with performance and load testing.
You should be motivated by a desire to solve the most important problems, obtain unprecedented results, and push your methods to their maximal performance.
Responsibilities * Optimize Tendermint consensus protocol codebase for speed, reliability and performance, including making PRs as needed to the OSS Tendermint project * Troubleshoot reliability issues of distributed systems, e. g. connection losses between Tendermint nodes under heavy load * Monitor the infrastructure and blockchain performance to identify issues * Measure and improve server response times in different conditions and environments * Guide protocol design decisions
Requirements * 1+ years experience with Golang, C or C++ * 4+ years of experience in a systems engineering role * Deep experience with networking and concurrent computing * Deep experience with Unix/Linux systems * Experience with AWS/GCP * Comfortable operating in dynamic environments

We are seeking experienced engineers to join our Platform Engineering team. In this role, you will be key to the development and management of the Wanderu technology platform. As a member of this team, you will work closely with others in an exciting environment using the latest technologies including NoSQL and graph search technologies. You will start fast and ship features and fixes in your first week.
About you
You learned CS concepts in school like linked lists, graphs, Big “O” notation, search and sorting, but you wondered why everybody used a relational db for everything.
You thrive in an environment that doesn't get bogged down with red-tape and encourages creative solutions to complex problems.
You desire to have an impact with what you do and want to see what you build help people.
You know that there is never just one path to a solution and that the key is finding the solution that helps move the product and team forward quickly without sacrificing quality.
You like to travel and wondered how technology could have made the experience better.
When you run into every-day problems, you think to yourself “How can I automate this?" or "How can I make this work better?”
When you were a child, you disassembled your toys to see how they worked. Most of the time, the pieces came back together in the right order.
Your engineering career started on the front-end or the back-end, but you feel comfortable contributing across the full stack.

Ravelin is looking for a senior backend engineer to lead the development of a high volume fraud technology platform within a small tech team. You will be invited and expected to have opinions about the strategic direction of the company and products, as well as leading the development team from the front. A successful candidate will be willing learning new skills (machine learning, neural networks, python, golang, cloud automation etc), turning their hand to necessary tasks and working with complete autonomy.
Code for Humans
Your machine is happy if it compiles; your team is happy if they can understand what it does. Your pull requests are succinct and a pleasure to review, you have unit tests where it matters, and you understand that the code is not, in fact, the documentation.
Reliable & Resilient Software Not for you the happy path or the assumed network. That habit of yours of assuming the worst and planning for it has earned your stripes in the world of running software at scale under real-world conditions.
Tools for the Team
Whether it's a smart command line utility or a core internal library, you excel at improving everyone's lives by removing repetition & common sources of error, and by solving hard problems in accessible ways. You build internal processes that are so reliable they melt into the background but are key to getting work done.
APIs
You've been on the receiving end of APIs good and bad, and want to delight our customers with the high quality they expect. You know that whilst everything should be JSON, sometimes you have to get your hands dirty with some SOAP for that critical integration but know how to isolate the contagion.
We are an equal opportunity employer and value diversity in our company. We do not discriminate on the basis of race, religion, colour, national origin, gender, sexual orientation, age, marital status, or disability status.
