About Us

Chorus One is one of the leading operators of infrastructure for Proof-of-Stake networks and decentralized protocols.

Position Overview

As a senior software engineer, you will join our rewards data team to assist in building and maintaining user-facing and internal applications to support rewards reporting and financial performance monitoring.

The networks rewards us for that in their native token. Keeping track of those rewards over time is a hard problem, because ironically, blockchains typically don’t expose convenient APIs to extract this data in a useful format. This is why we build our own automation, and integrate with third-party data vendors. Your work will power internal reports and dashboards, as well as external customer reporting, and rewards data APIs.

Key Responsibilities

• Design and develop new features. Discuss with internal stakeholders to clarify how our next feature should look, discuss with fellow engineers how it should be implemented, and then drive implementation to completion.
• Support and collaborate. Review and discuss engineering designs, review code, help fellow engineers, and work with other teams such as platforms engineering, customer success, business development, and our networks team, to get them the insights they need.
• Innovation and continuous improvement. Seek to simplify, optimize, and secure our staking services and systems.
• Take part in on-call rotation approximately 2 days per month. You will be responsible for building APIs used by external parties, which come with an uptime requirement.

Job requirements

What we are looking for:

• 4+ years experience as a Software Engineer.
• Experience with operating and maintaining server-side software in production.
• Experience with Python (most of our rewards data automation is written in Python)
• Other backend software at Chorus One is written in a mix of Rust and Go, experience with these is an advantage.
• Experience using SQL databases, preferably PostgreSQL.
• Experience with implementing REST APIs.
• Strong communication skills and ownership to drive new features independently.
• Interest in blockchain technology, in particular distributed systems and consensus algorithms.
• You are able to work in the following time zone: Switzerland ± 6 hours.

We use AI, machine learning, and natural language processing in our products.  You do not need to have experience with this, but if that is something you would like to learn, there are plenty of opportunities for that.

Our goal is to have you grow into a leadership role to lead our software development efforts under the direction of the CEO.  The CEO is a patent attorney and our products relate to automating the work of patent attorneys.  

Who You Are

• A well-rounded, product-focused software developer who thrives on building products that end users love.

Company Vision

Our vision is to streamline patent practice so patent attorneys can excel and thrive.  25% of patent attorneys are already using Patent Bots and we want to expand so that all of them are using our tools! 

Company Culture

These company principles are to aid in decision making as a company.  When making hard decisions, these principles should help point us in the right direction.

• Keep it simple – From product design to customer contracts and how we operate as a company, eliminate complexity to focus on what is important.
• Value our customers – Our customers are our employers and investors.  We need to provide great value to them so that they are happy to pay for our products (though it is ok to fire bad customers).
• Employee growth and satisfaction – We want employees who believe in our principles, are a great match for their role, love what they do, and have an impact on the success of the company.
• Profit-led growth – Consistency is more important than speed.  Doing the right thing is superior to doing a lot of things.  Stay aligned with our customers.
• Product-led growth – Be so good they can’t ignore us.  Our customers are our best sales people.
• Be different – Be deliberate and don’t do things just because other people do them.  Be authentic.
• Don’t be boring – We need to stand out among all the noise.  Everything we do in public should provide value to the audience.

Hiring Process

• Our first step is to ask applicants to fill out a Google form with some relatively easy questions.  Our goal here is to be able to easily weed out applicants who apply without reading the job post or who are not qualified.
• A short screening interview for qualified candidates.
• An interview with the founder who is also the primary developer.
• A take-home programming challenge that should take about an hour.
• A joint-coding session with the founder.
