Scala engineering for systems that can't be wrong

Tailrec builds and staffs backend systems in Scala for fintech and data-intensive companies — trading platforms, payment rails, streaming pipelines. Senior engineers only. When you email us, an engineer answers.

The problem we solve

Why teams hire a Scala development company instead of recruiting

Hiring a senior Scala engineer takes 3–6 months in the current market, and the good ones aren't applying to job ads. Meanwhile your Pekko cluster still needs migrating off Akka, your Spark jobs still cost too much, and your roadmap doesn't pause.

We exist for that gap. You get engineers who have already shipped production Scala — not generalists who “can pick it up” — without the recruiting cycle, and without a 12-month commitment if the need is temporary.

What we do

What we do

Staff augmentation

Senior Scala engineers embedded in your team, your repos, your standups. Productive in week one because they've seen your stack before.

Scala staff augmentation

Custom development

A defined system, built end-to-end and handed over with documentation your team can actually maintain. Fixed scope or milestone-based.

Custom Scala development

Consulting & code review

Akka-to-Pekko migration plans, effect-system architecture reviews, performance work on Spark and Kafka pipelines. Short engagements, concrete deliverables.

Who we are

Built by engineers, run by engineers

Tailrec was founded by [FOUNDER NAME], [one sentence of verifiable track record], and [CO-FOUNDER NAME], [same standard].

There's no sales layer. The person who scopes your engagement is the person accountable for its delivery. That's slower for us and better for you.

Timezone coverage

Working hours that cover two continents

We operate from New Zealand — which sounds like a liability until you look at a clock. Our working day overlaps US West Coast afternoons and hands off cleanly into the European morning. Your standup gets a live human; your overnight becomes our workday.

For US teams, that means code review turnaround while you sleep, not a 10-hour dead zone.

How it works

What engagement looks like

01

Technical call (45 min, free)

With an engineer. We'll tell you on the call if we're not the right fit — including if your problem doesn't need Scala or doesn't need us.

02

Written scope

What we'll build or who you'll get, milestones, cost. No discovery-phase invoices.

03

Two-week checkpoint

If it's not working, you say so and we part ways at cost. This exists because we're new and you're taking a risk on us — we'd rather price that risk in than pretend it doesn't exist.

Talk to an engineer

30 minutes, no sales deck, and a straight answer on whether we can help.
