Looking to hire Scala developers who genuinely think in functional terms, not Java developers who happen to compile Scala? Scala's power comes from combining functional programming with a strong static type system on the JVM, but that power is only real in the hands of someone who understands immutability, type classes, and effect systems. Hire the wrong person and you get Java written with Scala syntax: mutable, imperative, and missing the whole point.
Scala talent is concentrated in two demanding worlds: big data engineering with Apache Spark, and high-concurrency backend systems with Akka and the typed actor model. The instincts for each are different, and both reward type safety that catches whole classes of bugs at compile time. We match you to a developer who has shipped in the world you actually live in.
Whether you need one engineer to build out a Spark pipeline or a team for a full functional backend, we offer flexible engagement models that fit your data scale and your timeline.

Why Hire Through Us
Benefits of hiring developers through Hevcode
Pre-Vetted Functional Engineers
Every Scala developer is tested on functional design, the type system, and Spark or Akka depth, with proven production JVM experience.
Quick Onboarding
Start working with your Scala developer within 48 hours. They get sbt building and start contributing to your pipeline or service fast.
Flexible Engagement
Choose hourly, part-time, or full-time. Bring in scarce Scala and Spark expertise for a data initiative without a permanent hire.
Direct Communication
Work directly with the engineer building your data pipeline or backend. No translation layer between intent and implementation.
Timezone Overlap
We guarantee at least 4 hours of overlap with your working hours for real-time design and review.
Risk-Free Trial
Start with a 1-week trial. If the Scala developer is not the right fit, you pay nothing.
Engagement Models
Flexible hiring options to match your needs
Dedicated Developer
A full-time Scala engineer working exclusively on your project, owning the design of functional, type-safe pipelines or services.
Ideal for: Teams building data platforms or high-concurrency JVM backends long-term
Development Team
A managed team of Scala and data engineers plus QA and a technical lead, ready to deliver a full Spark platform or backend end to end.
Ideal for: Enterprises building big data or reactive systems needing complete delivery
Hourly/Part-Time
Flexible hours for targeted work like tuning a Spark job, building a Kafka consumer, an Akka service, or a focused data transformation.
Ideal for: Pipeline tuning, migrations, code reviews, and consulting
Hiring Process
Simple 4-step process to get your developer
Share Requirements
Tell us what you are building in Scala, whether it is a Spark pipeline, an Akka service, or a functional backend, plus your data scale and Scala version.
Developer Matching
Within 24 hours we present 2-3 pre-vetted Scala developers matched to your domain, with profiles, sample work, and availability.
Interview & Select
Interview the candidates, give them a real Scala or Spark problem if you like, assess functional depth and fit, and choose your engineer.
Start Building
Your Scala developer joins within 48 hours. We set up repository and cluster access, communication channels, and kick off the work.
Frequently Asked Questions
Common questions about hiring developers
What is the experience level of your Scala developers?
Our Scala developers have 4-9+ years of JVM experience with strong functional programming skills, fluent in immutability, the type system, and either Spark for big data or Akka and Cats/ZIO for backend systems. Many work across both Scala 2 and Scala 3.
How quickly can a Scala developer start on my project?
We can have a developer onboarded and contributing within 48 hours of selection. Scala talent is specialized, so we keep a vetted bench, and for urgent needs we can often expedite to 24 hours.
What if the Scala developer is not a good fit?
We offer a 1-week risk-free trial. If the engineer is not the right fit for your pipeline or service, we replace them at no cost or give a full refund. After the trial we can still swap developers with one week's notice.
Do your Scala developers work in my timezone?
Yes. We guarantee a minimum 4-hour overlap with your working hours, and many of our Scala engineers flex their schedules to align with US, EU, or APAC teams.
How do you ensure Scala code quality?
Our developers write idiomatic, immutable, type-safe code, lean on the compiler and type system, add ScalaTest and ScalaCheck property tests, profile Spark jobs for skew and shuffle, and use scalafmt and Wartremover. They integrate with your existing review and CI process.
Can I hire a complete Scala team?
Yes. We provide full teams of Scala engineers, data engineers, a QA specialist, and a technical lead, including Spark-focused big data teams, scaling from 2 to 10+ members.
