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. Either way, you are a great detective and passionate about pushing the performance of your infrastructure to its limits, without compromising on safety or stability.
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
Bonus Points * Background in networking or distributed systems * Familiarity with Cosmos / Tendermint * Proficiency in protocol-level blockchain development * Contribution to open source software * Degree in STEM field, especially software engineering or computer science related. * Experience in small startÂup environments helping large enterprises. * Experience with a distributed team

Role Overview:
You are someone who loves building software that people genuinely love using. You want to make things that excite people. That add joy to their daily lives. And you want to do it with people who are working towards a common goal and see your success as their success. You will be joining a team that values getting things done, helping others get things done, and building towards an amazing future.
Our customers are designers and engineers who care about the details, the small stuff. Every bit of the customer experience is important and we’re not just talking about features. Every bit of friction is something that gets in the way of creativity and innovation. Our job is to foster both of those things.
You like to go really deep because you love to unravel things, both to understand how they work and to use them beyond what others thought was possible. You love both new and interesting things, but also things that are proven to work because you’ve been burned by the new and shiny before. You aren’t afraid to tackle any problem head on with the support of talented people to help. You enable people to do their best and achieve things together they never thought possible. Because you care. Because you genuinely want to deliver something that people love.
If that sounds like you, we want you here. We need you here! We have super ambitious goals that we think will genuinely make a difference for our customers. You’ll help us achieve those goals.

Requirements:
InVision has both management and individual contributor career progression tracks for software engineers. This is an individual contributor role.
