Senior Full-stack Software Engineer


Trineo delivers custom solutions for global organizations and is a well recognized Heroku and Salesforce partner since 2010. Our work tackles system integration and data brokering, API development and highly specific customer, employee applications.

As an agile team, we present a complete service offering -- with senior advisory, product and project management, UX and engineering (back end and frontend).

We’re known for our ability to ship valuable work into production in complex and challenging environments.

We’re looking for a Senior Full-stack Developer to join our Boulder team. You’d be part of a growing global professional services practice in the process of expanding our US footprint. In addition to our Boulder office, Trineo has offices in Christchurch, NZ (our headquarters), Auckland, and Sydney, Australia. Remote working arrangements are available in the US (for candidates who are legally authorized to work in the US).

Trineo is and will always be a small team, with 70 team members worldwide, growing slowly and deliberately. We're not looking for gurus, rock stars or ninjas. We're interested in working with level headed people who operate with a sense of confidence, humility and humor. Our global footprint truly brings to life our belief in celebrating diversity.


We’re looking for candidates with 5+ years experience. Candidates should have deep knowledge of either back end (Rails) or front end (Javascript) technologies with the ability to debate technology decisions up and down the stack. This position will not have direct reports but will require aspects of leadership for a specific client and/or development team. These aspects of leadership require an individual to demonstrate ownership of features which require research and a clear articulation of pros / cons of available implementation strategies. Furthermore, the role requires a consultative approach which seeks to develop a consensus on major decisions within the entire team (Trineo and our customers). Our point of view is that a decision made with research, peer review and collaboration is one which will have the most sustainable outcome for everyone.

Above all else, we’re looking for candidates who will be the best addition and help curate the team and culture.

If you’re a good candidate for this position, here are some characteristics you embody:

  • Must be highly articulate in a back end and/or front end technology, with a preference for Ruby and/or Javascript
  • Experience working across the entire stack
  • Comfortable writing SQL queries, optimizing query performance and DB design.
  • Experience with the development and consumption of APIs
  • Experience with the development of frontend applications that consume aforementioned APIs
  • Excellent working knowledge of Git
  • Experience working with cloud hosting technologies (ie Heroku and AWS)
  • Experience with optimizing high performance applications under significant load
  • Thrive when working within an Agile team
  • Enjoy working in a cross functional team composed of UX, BA, PM, Development
  • Experience working with a distributed / remote team

Our typical stack and methodology:

  • Development: Ruby, Rails, Javascript, Webpack, React, CSS/SASS, HTML
  • Data: Postgres, Redis
  • Testing: Rspec, Capybara, Jest, CI, BrowserStack
  • Infrastructure: a strong understanding of cloud platforms: Heroku, AWS componentry and a decent handle on Unix

We also adhere to agile delivery (Scrum/Kanban), continuous integration, test driven development, consistent peer review and pair programming.

This expertise would be nice to have:

  • Service Oriented and Monolithic Architecture
  • Identity Management (Authentication and Authorization)
  • A thorough understanding of security principles, common exploits and an interest in recent advisories and corresponding mitigation strategies.
  • Culinary prowess, baking skills are looked upon very favourably. Seriously, we have a team which is composed of a diverse range of people that have a number of hobbies outside of work.


We have a comprehensive benefits package which includes generous Medical, Dental, Vision Insurance, a free Eco Pass, Simple IRA option, generous PTO, flexibility, bi-weekly in-house massage and the opportunity to travel to global Trineo offices.
