Clearmatics is a protocol engineering company. We are building a new financial market architecture that is more open, fair, and resilient than the legacy systems that are in use today. We develop protocols and software that create new markets for risk and more efficient infrastructure for trading, backed by a robust and scalable blockchain network, and secured with modern cryptographic techniques and economic mechanism design.
Clearmatics is based in London but operates on a 'remote first' model. We welcome candidates from all over the world. We have close ties to the Open Source and Ethereum communities, with Vitalik Buterin as an adviser.
The Engineering team at Clearmatics is responsible for developing our blockchain software at Layer 1 and Layer 2. At the core of our stack is the Autonity client, the node software that powers our blockchain network. It is based on Ethereum (go-ethereum) and is secured by Tendermint Proof-of-Stake consensus. 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.
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.
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.
We are looking for a track record of:
Preferred experience with, but not required:
Delivering secure and well-tested solutions that scale:
Strive to take ownership of a project from ideation to delivery and maintenance. Your experience provides a framework for you to work independently on several initiatives which will provide significant and measurable value to our customers. Seek opportunities to develop horizontal technologies that benefit multiple teams. Build and automation tools to increase the quality of all teams at Ferrum.
Communicate and document everything. At Ferrum, we are a distributed team. A culture of sharing and documentation allows everyone to work together. We are looking for a practitioner of clear documentation that is well-maintained. You adapt your communication style to suit different audiences and follow up on feedback to ensure positive outcomes.
Are a team player. Ferrum is a high-growth, venture-backed, fast-paced startup. This means that while the team members we’re hiring will fully own their functions, we expect them to understand adjacent roles and responsibilities in order to support and sometimes contribute.
Are an out-of-the-box thinker. In a fast-paced startup environment, much of our success hinges on our ability to think differently from competitors, counter-position, outmaneuver, iterate rapidly, and present compelling messaging that differentiates us from the pack.
Think healthcare can be better and want to have an impact in the industry. Ferrum’s team is first and foremost, mission-driven. Our mission is to help hospital systems use AI to improve patient care, and the work that we do impacts patient lives every day.
We are looking to hire remote principal engineers as individual contributors to design, develop, test, deploy, maintain, and improve Humanitec. You should have significant professional experience in building highly scalable distributed systems. CS degree and experience in dev productivity tools are a plus. Languages: predominantly Go. Everything is on Kubernetes. We pay top 5% in the market, stocks are part of the package. Work is fully remote and we work exclusively with senior engineers in small, lean, and self-organized teams. We currently prefer time-zones UTC-1 to UTC+3.
We are pioneering a new category of tooling called “Internal Developer Platforms”. Built for some time in companies such as Spotify, Github, Airbnb, and others, we are providing the fastest way for teams to build their own Internal Developer Platforms. Internal Developer Platforms provide a developer experience as simple as Heroku but on top of the tech and tools the team uses already. They allow ops teams to stay in control while enabling developers to self-serve the tech they need. Do you want to spin up an environment to do some quick testing? No problem! Need to clone Production to troubleshoot an issue without risking more problems? Easy! Need to stand up a new database for your service but ops is busy? Piece of cake! We serve customers from startups to unicorns.
The majority of our company are engineers. Our management team is made up of Ex-Google, Ex-Mckinsey, and serial entrepreneurs. We are backed and advised by experts such as Sohaib Abbasi (Oracle, Redhat, New Relic), Mirko Novakovic (Instana, IBM), Jason Warner (Github, Microsoft), and Chris Schagen (Contentful). We are well on track for our Series A at the beginning of 2022.
We're looking for people who could land a job at the likes of Google, Amazon, or Microsoft - but prefer the excitement, challenge, and daring of being part of a disruptive startup. We focus on your talents and personality - your background, origin, or gender will never make a difference to us.

Jetstack is a Venafi company.
Venafi is the undisputed heavyweight champion in Machine Identity Protection. Why? Because we created the category and are light years ahead of anyone that would consider competing! Gartner has recognized Venafi as number one in our space and as it turns out, one is NOT the loneliest number!
Venafi is the inventor of the technology that secures and protects keys and certificates. Venafi protects machine identity types by orchestrating cryptographic keys and digital certificates for SSL/TLS, IoT, mobile and SSH. Many of the largest organizations in the world use Venafi.
Billions of dollars have been spent protecting usernames and passwords and almost nothing protecting keys and certificates—organizations are just now realizing that protecting keys and certificates is as important as protecting usernames and passwords. The bad guys know this and are using stolen or forged keys and certificates to attack networks and steal data. In fact, Gartner says 50% of network attacks will use certificates.

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 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.
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.
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*
Cloud Foundry engineers participate in an on-call rotation with their team to support software they work on.
Pivotal is an Equal Employment Opportunity employer that will consider all qualified applicants, regardless of race, color, religion, gender, sexual orientation, marital status, gender identity or expression, national origin, genetics, age, disability status, protected veteran status, or any other characteristic protected by applicable law.
