Position Summary


We're looking for an experienced, solution-focused software engineer to support frontend development of our web and mobile applications. You will have significant responsibility and influence in shaping those applications as we evolve our patient-centered experience in close collaboration with the rest of our product, design and software engineering teams.Our mobile apps are written in React Native w/ TypeScript. Our web application is written in React using Next and TypeScript. A significant percentage of JS code is shared across our Android, iOS and web platforms.

The DevOps environment leverages a whole lot of GitHub and CodePush with various levels of automated testing for frequent releases to all clients. Expertise in these areas is a huge plus, but having familiarity with similar technologies can be fine substitutes. You will need to have a passion for quality and an ability to understand complex systems. Above all, you should be passionate about solving real world problems, and bringing that value to our members. Why is this a great opportunity for a senior software engineer?


  • The problem domain and our approach to solving it is super compelling. We're bringing together data sources that have never been joined, building models of a GI patient that have never been built, and discovering new GI health insights that help real people to manage and support their real medical conditions.

  • It's still early enough that there’s a lot of decisions and new discoveries to be made, so this is your chance to get in early and help shape our future.

Other things about our environment you should be aware of:


  • We're still a small company, which means that everyone still wears a lot of hats and we need engineers who are comfortable with ambiguity and working across a wide variety of challenges. That said, our existing engineering team has built an extremely efficient working environment based on best-in-class hosted SaaS frameworks that greatly minimize the overhead in deploying and supporting software in production. 

  • We're all really passionate about improving clinical outcomes for our members and truly advancing the GI health space. Most of us also have personal (direct/family/friend) connections to GI health problems. Whatever it is that fuels you, we're on a mission to build something much larger than ourselves here and looking for another partner in driving that mission forward.

Responsibilities Include:



  • Develop the kind of software that you’d want to inherit from another developer (documentation, test coverage, logging, metrics, etc.) 

  • Collaborate with the rest of your engineering team on design, planning and code reviews

  • Partner with product stakeholders on ideation, feedback and refinement of solutions that meet our business needs 

  • Keep learning

You'll be a good fit here if you are:



  • A team player. You like collaborating closely with other engineers, often through pair programming, design & code reviews

  • Empathetic to our members’ GI health conditions and are driven to improve their outcomes

  • Security oriented. We take the stewardship of our customer's healthcare data seriously, and take no shortcuts to protect it

  • Comfortable with a distributed workforce. We interact with each other via video chat, Slack and PR comments

  • A self motivated, creative problem solver

We are proud of the team culture that we foster today, which is extremely friendly and supportive while constantly reaching to raise our own standards of engineering. We're really excited about what we're building, and usually having fun building it together. If all of that sounds fun to you too, we'd love to meet you.

Desired Qualifications



  • Degree in Computer Science or a related field, or equivalent experience

  • 4+ years of demonstrated experience building and supporting software applications

  • Proficiency with JavaScript, TypeScript, and React Native

  • Ability to execute front end and mobile development throughout the entire development process. Driving continuous improvements from leveraging modern tools and frameworks that enables us to release more frequently.

  • A passion for automated testing

  • Outstanding communication and interpersonal abilities with colleagues, business partners, and vendors alike

  • Bonus:

  • Any experience with native iOS/Android code via Objective-C, Swift, Java or Kotlin 

  • Familiarity with Google Cloud Platform (GCP)/Firebase frameworks, such as Cloud Firestore, Cloud Identity, Dynamic Links, etc..

  • Experience with medical, healthcare and/or population health data. Double bonus for familiarity with FHIR and/or other healthcare data standards

  • Experience working in a HIPAA regulated environment (or other regulated industry) and supporting data security and privacy controls

Cylinder is an equal opportunity employer.

We believe safe spaces where everyone can be their authentic selves is the key to a successful team so we welcome and embrace all identities, cultures, and backgrounds.

Life at Vivante Health

Vivante Health is an innovative healthcare company whose mission is to help those with invisible, neglected, and stigmatised chronic illness overcome barriers standing in their way to optimal care and for every day to be their Best Day Forward. We are starting with digestive diseases because an astonishing 70M in the US live with these conditions, more than diabetes or any other chronic condition, but they go on unrecognised because no one really wants to talk about them. Chronic digestive diseases affect home life, work performance, and even simple social functions. We believe now is the time to bring something special to support people with these conditions and to educate those others who don't understand how someone who doesn't look sick is really struggling on the inside. We don't focus on just the condition. We focus on understanding the person. We believe that the personal touch is the difference-we've built our program on the principle that we are not just there when there is an acute health issue, but there early and often to build that strong relationship that is steeped in trust and key to providing meaningful and lasting support. While we are a young company we have years of collective experience in clinical care, education, and consumer technology. Everyday our passion drives us to create something new, useful, and collaborative that provides people with invisible, neglected, or stigmatised diseases and their families with the support and tools that will make big differences in the quality of their lives.
Thrive Here & What We Value* Small friendly team culture* Advancing GI health space* Embracing diversity* Remote workforce supported by digital investors* Leading SaaS frameworks for efficient software deployment* Real solutions for digestive symptoms* Empowerment through technology and science* Focusing on neglected healthcare conditions* Collaborative environment with shaping opportunities* Personalized medical nutrition therapy
