Where this fits

Built for the moments you can't postpone

We don't take work just to take work. This service exists because the problems below are the ones we keep being hired to solve, and the ones we've shipped through more than once.

  • You have a roadmap; recruiting senior engineers in-house keeps slipping
  • Need to ship a quarter-defining release without doing six months of hiring
  • An engineer is on parental leave / left, backfill needed for a focused window
  • Have a niche need (mobile, AI, infra) and don't want to hire it permanently
  • Internal team strong on delivery, missing senior frontend / design judgement
  • Want to test working with us before committing to a fixed-scope build

What we ship

Solutions, not slide decks

Each line below is a real deliverable shipped on past engagements, with an honest scope and a metric where it makes sense.

01 / Scope

Senior engineering roles

Frontend, backend, full-stack, infra, mobile, AI / data, placed individually or as a small pod. Every roll-on has 8–15 years of shipping behind them.

10y+ average experience

02 / Scope

Product design & design ops

Senior product designers who can run a design system, ship UI inside your sprint, and pair with engineers, not just hand off Figma.

03 / Scope

Embedded pods

Pre-formed 2–4 person teams (PM / design / engineering) for quarter-scale initiatives. They ship inside your tools, your stand-up, your code review.

04 / Scope

Delivery lead per pod

Every roll-on of two or more includes a TengenX delivery lead, your single point of accountability for velocity, quality, and weekly reporting.

Bi-weekly written review

05 / Scope

Onboarding playbook

Repo access, runbooks, stack tour, first-week shadow → second-week ship. We've onboarded into existing teams in under 48 hours when it mattered.

<48h fastest onboard

06 / Scope

Replace-within-5-days SLA

If a roll-on isn't working, for any reason, we replace within five business days at our cost. The point is your delivery, not our retention.

Common questions

Honest answers, no sales theatre

How is this different from a body shop or freelance marketplace?

Three things. (1) Every roll-on has 8–15 years of shipping behind them, no juniors, no padding. (2) Pods of two or more come with a TengenX delivery lead so you have one accountability surface, not five contractors. (3) If the fit is wrong, we replace within five business days at our cost. We're being judged on your delivery, not on billable hours.

Can roll-ons work in our timezone?

Yes. The team is split across Berlin, Bangkok, and Dubai, so we have real-time overlap with EU, GCC, and APAC, and we get into US business hours through European morning. We agree the overlap window with you on the brief call and lock it as part of the engagement.

Do they use our tools or yours?

Yours. Roll-ons live inside your Linear / Jira, your GitHub, your Slack, your stand-up. We bring our delivery hygiene, not a separate stack you have to integrate with.

What's the smallest engagement you take on?

A single senior contributor for one month, or a five-day trial week with a single contributor. We don't take on hour-by-hour gig work, the math doesn't work for the kind of delivery quality we want to be associated with.

What if a roll-on isn't a fit?

Tell us. We replace within five business days at our cost, and we'll often pre-emptively flag if a fit feels off in the first two weeks. The replacement is part of the rate card, there's no separate fee, and you don't lose sprint time.

Ready when you are

Let's get the right people in your sprint by next week.

Tell us the role, the stack, and the next quarter's outcomes. We'll come back with 2–3 shortlisted profiles, code samples, and a rate, usually within five business days.
