Where our Ruby On Rails developers work

Hours logged by Ruby On Rails developers on each product, the size of the team, and how long we have been on it. These are the engagements with a case study you can read — not everything we have built in Ruby On Rails, only the part we can show you. Hours are counted from 2022, when our time tracking moved to its current system; a few of these relationships started earlier than that.

What we take on in Ruby On Rails

  • Products that have outlived two or three roadmaps

    Four of our Rails engagements have run since 2022 and are still shipping. The work is version upgrades, schema history and features landing on top of decisions made years ago — not a greenfield app that will be someone else’s problem by spring.

  • Rails and Ruby upgrades without stopping delivery

    Moving a live application forward a major version while features keep landing, which is a scheduling problem as much as a technical one.

  • Applications whose original team has gone

    Reading a codebase nobody can explain, writing down what it actually does, and getting to a state where a change is safe. This is how most of our Rails engagements started.

  • Performance that has a number on it

    Slow queries, N+1s that only appear at production volume, background jobs that pile up on a Monday. Measured before and after.

How a Ruby On Rails engagement starts

  1. Days 1–2

    A call, then a written profile of what the person will own. If the brief cannot be staffed at the budget, you hear it here rather than after three interviews.

  2. Days 3–14

    Rails is our largest practice, so a match from someone rolling off is more likely here than anywhere else. When we recruit, our closed Rails roles run a median of 31 days from opening to a signed offer.

  3. First week on the project

    Get the app running locally, read the migration history, and come back with the three things that will slow the team down. On an inherited Rails app that is the whole week and it is worth it.

  4. Every month after

    The hours logged, published the way they are on this page. You can scale the team down without renegotiating the arrangement.

How a Ruby On Rails engagement is shaped

  • A team that stays

    Three to eight developers with a project manager, running for years rather than a quarter. Four of ours have run since 2022 and this is what we are built for.

  • One developer who knows the app

    Several Rails products here run perfectly well on a single developer who has read every migration. Cheaper than a team and better than a rotation.

  • Upgrade and rescue work

    A defined engagement to get a stalled application onto a supported Rails and Ruby version, after which you decide whether to keep the team.

Working with a Ruby On Rails team

Where the team sits

More than half our engineers now sit in Latin America, with most of the rest in Eastern Europe — Brazil, Argentina, Ukraine, Poland and a scattering of others. On engagements that run for years the overlap question is not really about hours, it is about habit. Our European developers cover the US morning and the Latin American ones the full working day, but what makes the four Rails products we have staffed since 2022 work is that the same people are in the same standups every week.

How people get here

Rails has the best funnel of any stack we recruit for: 21 vacancies since 2021, 1,623 candidates, 16 offers — about one hire per 101 applications, against 130 on React and 157 on Node. It is also our largest practice, so a match from someone rolling off is more likely here than anywhere else.

Why ScrumLaunch for Ruby On Rails

work-with-us-0

28 days to a signed offer

The median across 167 hires since 2021, from opening a role to a signed offer — a quarter of them inside 16 days. When someone is rolling off another engagement it is days instead, and each stack page publishes its own number rather than this average.

work-with-us-1

One hire per 130 applications

What our front-end funnel actually filters, and it runs from one in 63 to one in 219 depending on the stack. We publish the ratio per stack instead of claiming a percentile, because the ratio is the thing you can check.

work-with-us-2

Three levels of quality control

A project manager on your standups, a tech lead over the architecture, and scheduled code audits — 150 of them across 61 client repositories since September 2025, scored the same way we score our own.

work-with-us-3

One month trial period

If you aren't fully satisfied, we will staff a replacement at no cost and you won't pay for the unsuccessful trial period.
