CircleCI is looking for an experienced Fullstack Engineer to help us launch a new team focused on Notifications. We need someone who enjoys diving into existing systems, designing new systems, and solving customer problems.

The Notifications team will be shaping the future of how we deliver information to customers. You’ll be part of charting a new path and defining a domain while solving a targeted set of customer problems. We care about delivering information from the basic work status level to data that can help our customers make informed decisions. While some of what we do will be that exciting green field, some of it will also be navigating existing notification systems and determining their future.

As a team member, you’ll help address important customer problems and work with cool people!

What You’ll Do

• Design & Build: Develop new features, simplify existing services and scale our systems as we rapidly grow and evolve.
• Write Code: Produce sustainable, testable, high-quality, and high-performance code that you can be proud of.
• Support and Maintain: Debug and support microservices in a complex distributed system.
• Cultivate Observability: Foster a culture of monitoring and observability by using operational data to help your team increase the stability, performance, and usage of our systems.
• Collaborate and Innovate: Partner with members of a multi-functional team to dive deep into business problems, explore creative solutions, weigh design tradeoffs, craft effective user stories, and prioritize tasks to deliver maximum value in a balanced and incremental way.

What You’ll Bring

We’re seeking someone who thrives in a collaborative environment, is curious and interested in learning, brings strong communication and teamwork skills, and helps others grow by sharing their expertise and encouragement.

Below you can find a list of skills and practices we value in candidates - you don’t need to be experienced in all of them to apply!

• Experience: 5-7+ years of professional experience building and debugging distributed systems in production environments
• Full Stack Expertise: A backend-focused engineer with a workable knowledge of frontend development. We value versatility and enthusiasm for enhancing user experience, API design, and system architecture.

Code Quality: Proficiency in writing functional code that’s easily readable, testable, and maintainable.

• Language Proficiency: Experience in Golang is preferred as this role will work primarily in Golang, with some Clojure. Data persistence may include Postgres, MongoDB, Redis, and other cloud storage systems like s3. Frontend work will be primarily in React. The person in this role should have working knowledge of event streams and event-driven architecture. You'll use RabbitMQ heavily but not exclusively for the messaging framework.
• System Design: Experience designing systems and leading large projects from clarifying requirements to breaking down work to delivery.

• Adaptability: Able to manage the ambiguity of a rapidly growing company- adjusting to changing priorities, making conscious tradeoffs when guidance is limited and information is incomplete, and instituting best practices from scratch when needed.

We’re Particularly Interested In These Work Styles

• Transparency & Collaboration: Embrace working transparently within a distributed team environment.
• Incremental Delivery: Prioritize regular and incremental delivery over achieving perfection.
• Continuous Learning: Commit to personal and team growth through continuous learning and improvement.
