Carbon Five is a digital product development consultancy. We partner with our clients to create exceptional products and grow effective teams.


We have openings for this position in New York NY, San Francisco CA, Santa Monica CA and Chattanooga TN.

Carbon Five is a digital product development consultancy. We partner with our clients to create exceptional products and grow effective teams in a healthy, sustainable way.

Over the last 20 years, we have learned a lot about what it takes to do this successfully, and in the process, we have created some of the most highly-valued digital platforms, mobile apps, websites, and more.

We offer great benefits, reasonable work hours, and intriguing projects in a welcoming work environment where employees feel safe, have fun, and learn every day.

Working at Carbon Five

At Carbon Five, you will work on a single cross-disciplinary product development team—engineers, designers, and product managers—working full-time, side-by-side with one of our clients. Together, you will learn the problems they want to solve, get to know the people who are experiencing them, and design potential solutions. You will iteratively develop and release working software using established agile development practices like experiment-driven design, test-driven development, small and frequent releases, and continuous integration and deployment.

Your Role On The Team:

As a Senior Software Engineer, you will work with the rest of your team to scope, design, build, test, and deliver new features. You will pragmatically advocate for agile engineering practices including test-driven development, collective code ownership, and continuous integration. You will work at all levels of the stack, sharing your expertise where you have experience and learning from your colleagues where you’d like to grow.

Your typical week may include the following:

  • Writing test-driven code while pair programming with other engineers
  • Working closely with stakeholders, product managers, and designers to shape product direction and discuss the feasibility of prototypes
  • Facilitating iteration planning meetings, helping lead the team in refining feature definition, estimating stories, and prioritizing the highest-value work
  • Helping non-technical collaborators understand technical requirements and constraints to inform scope and facilitate milestone planning
  • Mentoring less experienced members of your team, sharing your time, knowledge, and insights

About You

This job might be right for you if you:

  • Prefer collaboration over working solo
  • Take a collective approach to problem-solving and decision-making
  • Enjoy being given goals and finding ways to achieve them
  • Enjoy using your creativity and resourcefulness to tackle unexpected challenges
  • Enjoy participating in all aspects of product development including generating ideas, prototyping and building solutions, talking to users, testing outcomes, and integrating learnings into future work
  • Want to learn new languages, paradigms, patterns, and frameworks
  • Make technical decisions with a strong consideration for the capabilities and skills of the entire engineering team
  • Care about maintaining a safe, learning work environment, making space for innovation and professional growth

To be considered for this role, you will need:

  • Strong written and verbal communication skills
  • A high degree of empathy for others
  • Experience as a member of a professional agile software development team
  • The ability to communicate technical concepts and constraints to non-technical collaborators in an accessible way
  • The ability to develop, test, and deploy a complete application using at least one of the following languages: JavaScript, Ruby, Java, Elixir, Go, Swift, or Kotlin
  • The ability to address complex bugs on your own, effectively using developer tools to identify root cause(s) and define the work to resolve them
  • Strong knowledge of web fundamentals: including the TCP/IP stack, HTTP, the DOM, HTML, and CSS
  • Experience with multiple programming languages, one of which must be JavaScript or TypeScript
  • Experience with a commonly-used back-end framework (e.g. Express, Rails, Spring) and a commonly-used front-end framework (e.g. React, Angular, Vue.js)
  • Experience with a relational database, including familiarity with common query optimizations (e.g., using joins, eliminating N+1s)
  • Experience with a non-relational data store
  • Experience with a version control system, preferably Git
  • Experience deploying applications to a cloud environment

You’ll receive additional consideration if you have:

  • Experience consulting or working as a freelancer
  • Consistent involvement in the tech community (e.g. speaking at conferences and meetups, mentoring less experienced practitioners, leading or volunteering time to organizations committed to supporting underrepresented groups in our industry)
  • A track record of self-directed, continuing education
  • Experience leading teams of software engineers
  • Experience with multiple device platforms (e.g., web, iOS, Android)
  • Experience with multiple programming paradigms (e.g., object-oriented, functional)
  • Experience with cloud platforms (e.g., AWS, GCP, Azure), containerization tools (e.g., Docker), and/or orchestration systems (e.g., k8s)
  • Experience building accessible user interfaces
  • Experience implementing visual and interactive designs using advanced JavaScript and markup/stylesheet languages
  • The ability to architect applications at different scales, from server-side rendered web applications with hundreds of users to service-oriented architectures serving millions to fully decentralized networks usable by billions
  • The ability to assess security risks in an application’s design
  • The ability to model the domain and logical architecture of an application

An Inclusive, Sustainable, and Learning Culture

  • We check our ego at the door. As experienced practitioners, we understand that success is a team sport. We hire smart people who enjoy doing great work with others and who enjoy celebrating each others’ wins along the way. Teams solve problems and are given the support to do so without micro-management. We know every project is different, and only a dynamic team can deliver the quality and productivity that goes along with the name.
  • Your nights and weekends are yours. You should have a life outside of the office, and being well-rested is essential to doing good work. We work sane hours because we want you to come in each day fresh and enthusiastic, ready to build great products with a clear mind.
  • We don’t do trust falls. We genuinely like the people we work with and find that building strong relationships focused on trust occurs organically because we hire good people. We don’t have Forced Company Fun™, but we do enjoy getting together for (virtual) happy hours, tea time, holiday celebrations, and more. We look forward to attending more baseball games, gallery openings, boba tea outings, and playing tabletop games in-person again when it's safe to do so!
  • We want you to be yourself. Folks at Carbon Five are skilled in many things. We’re rock climbers, musicians, parents, coffee critics, and much more. Part of working with us is celebrating your passions while discovering and sharing one another’s. Check out some of the things that we’re passionate about.
  • We're here for you. As we look into the future, we’ll continue to grow in whatever ways make our employees and clients happy. There is no exit plan or 10-year strategy; we’re simply in the business of building a great place to work, where employees feel safe, have fun, and learn every day.


Our interviews are a four-step process that includes: an application review, a preliminary phone screen, a work experience & behavioral interview, as well as an “on-site” interview.

The “on-site” interview (now done remotely due to COVID) includes: an interview with other Developers, a second interview with Designers and Product Managers, a pairing exercise, and a conversation with the office’s Managing Director.

We use a standardized rubric for all candidates.


At Carbon Five, we want to build a team that reflects the diversity of identities in the communities in which we live. We strive to be a community where all are welcome to be themselves without fear of discrimination, and encourage each other to thrive. We strive to make concrete commitments towards promoting diversity, equity, and inclusion, and to be held accountable by being transparent with our process and impacts.
