Always be kind: a simple daily affirmation and one that feels more like a personal mission statement than a corporate motto -- but Pivotal isn’t just any corporation. Underpinning our world-class capabilities in cloud-native software delivery and agile development methodologies is one common thread: empathy. Not only do we want to transform the way the world builds software, we also want to make sure that sustainable pace, kindness, and diversity are at the core of every enterprise.
Known for taking an iterative approach, our 2000+ employees are empowered every day to help shape the way we build software. Pivotal is committed to open source, a diverse culture, and fostering safe spaces for all of our individual employees.
*You*
You are looking for a collaborative environment building distributed systems that enable enterprises to focus on their business rather than re-architecting a cloud platform from scratch. Pair programming has always been something that you wanted to try out.
Furthering your education has always been a goal of yours. Learning new programming languages and getting to work with Golang piques your interest.
Contributing to open source software makes you feel good about the transparency it brings to an organization's code quality.
*Us*
Agile concepts are at the core of our process. We have a whole host of Pivotal Practices around Test Driven Development, pair programming, team retrospectives, technical retrospectives and continuous integration. We are excited to teach these to you and innovate with you on their implementation.
We stick to a strict 8 hour a day schedule (with flexible start and end times). Although on-call rotations are part of most teams, incidents are exceedingly rare.
We pair in small teams of 4 - 8 people in our London office, conveniently located at Old Street. We use Slack to stay connected and Tmux for pairing. We are working hard to make sure that our distributed teams function as smoothly as our distributed systems.
You'll rarely be alone when developing; from pairing all day to 1 on 1 time with your manager, there is always a Pivot there to lend a helping hand. Mentorship from senior engineering leadership is built right into our process - you’ll always be empowered.
Making an investment in each Pivot’s professional development improves the organization as a whole. We encourage you to go to conferences or purchase those pricey O'Reilly books - and we’ll give you a budget each year to do it.
*Your Day*
As cliche as it may sound, every day is completely different from the next. We have a general framework for what our day looks like and the majority of it will be spent with your pair:
9:06 AM - Office-wide stand-up to build office cohesion and start the day off together.
9:10 AM - Team standup - discuss any blockers, choose pairs, maybe even tell a joke.
9:30-12:30 PM - Start pairing, tackle an open GitHub issue and open a pull-request.
12:30-1:30 PM - Lunch! Grab food from one of the many nearby restaurants, run an errand, or join a book club.
1:31-6:00 PM - Get back with your pair and start an acceptance test for a big feature.
While that schedule does look busy, don’t worry - we take ample breaks throughout the day. Take a walk to get boba, read a book on the balcony, play a game of ping pong, or chat with co-workers at the snack bar. Sustainable pace is held in high regard. We know there is a life outside of work, we want you to be able to spend time with family and friends.
*Desired Skills / Experience*
We know from experience that not ticking every box on the skills sections stops many from applying. You should apply regardless of your self-assessment because we want to hear from you.
*Nice to Haves*

Our decentralised platforms are built on smart contracts and decentralised applications, and are supported by backend services in Go.
We're looking to hire a Core Developer to expand our Layer 1 Engineering team.
ABOUT YOU
You're a systems programmer with good knowledge of Layer 1 protocols, and a passion for blockchain and decentralisation. You enjoy working to a high standard and writing code that is clean, performant, and maintainable. You appreciate the importance of careful design choices and can anticipate the impact of code changes on wider system behaviour. You can demonstrate a strong interest in blockchain and may even have open source contributions that you can highlight. You express yourself clearly in writing and in discussions.
RESPONSIBILITIES
You will be involved at all stages of the development lifecycle for the Autonity protocol and its blockchain node client (a fork of go-ethereum). These include: - Implementing new protocol features in Go and Solidity - Developing new distributed systems tests and frameworks - Contributing to protocol and design specifications - Working with members of the community to resolve issues - Your work will ensure that Autonity client is correct, reliable, performant, and secure. This will enable Autonity to serve as the foundational layer for a new ecosystem of decentralised markets.
