Sound familiar?
- Hiring a senior Scala developer full-time is taking months.
- Your Scala codebase has grown messy and every change breaks something else.
- Offshore hand-offs and time-zone gaps turn one-day fixes into week-long threads.
- You need someone senior enough to make decisions, not just close tickets.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.
What our clients say
"NextGen scaled us from 2 to 7 dedicated engineers in under a quarter. Enterprise-grade capacity, zero agency drag."
"Their R&D tax credit workflow platform paid for itself in the first filing season."
"AI-native from day one. Our IRS transcript pipeline runs 24/7 without a human in the loop."
"Property tax appeals used to take weeks. Their comp analysis tooling turned it into hours."
"The AI intake agent handles our tier-1 patient calls with a hand-off cleaner than our old call center."
"POS, inventory, ordering — all unified. We finally have one source of truth across every location."
"The procurement platform paid for itself in the first quarter of use."
"They shipped our matching engine in 6 weeks. Our old team would've taken 6 months."
"Enterprise-grade delivery without the enterprise-agency price tag."
"Their team plugged into our sprint on day one. Zero ramp time."

Hire US-based Scala developers from NextGen Coding Company for JVM services, Apache Spark pipelines, and streaming applications. Match the role to your codebase rather than the language alone: Scala 2.13 or Scala 3, Cats Effect or ZIO, Play Framework, Apache Pekko, or Spark's version-specific Scala requirements. Every engineer lives and works in the US, without offshore subcontracting.
Scala projects often need careful work at dependency and runtime boundaries: cross-built libraries, sbt configuration, Java interoperability, and distributed processing behavior. Clarify whether the priority is migrating language versions, maintaining an effect-based service, or investigating Spark data skew. Our senior engineers follow your working hours and join your standups. Book a 15-minute call to discuss the stack and the engineering work ahead.
Frequently asked questions
- Do I need a Scala backend developer or a Spark developer?
- Hire for the workload. Backend development may require HTTP APIs, effect systems, database access, and JVM service operations. Spark work calls for understanding execution plans, partitioning, shuffles, data skew, and storage formats such as Parquet. Some engineers cover both, but Scala syntax alone does not demonstrate the ability to diagnose a distributed data pipeline.
- How should we plan a Scala 2 to Scala 3 migration?
- Begin with a dependency inventory, your sbt build, and the Scala versions supported by key frameworks. Review macros, implicits, compiler plugins, and source compatibility before changing production modules. A candidate should explain incremental migration options, available cross-published artifacts, and tests that catch behavior changes. Spark dependencies can constrain language-version choices independently of your application preferences.
- Should I hire for Cats Effect, ZIO, or both?
- Prioritize the library already central to your application. Cats Effect and ZIO both support effectful programming, but their APIs, ecosystem conventions, and environment patterns differ. Interview for resource safety, cancellation, concurrency, and error handling in your chosen stack. General functional programming knowledge is useful, but should not replace the ability to navigate your actual service code.
- What should a Scala developer know about Akka and Apache Pekko?
- A relevant candidate should understand actor lifecycles, supervision, message delivery assumptions, and backpressure in streams. For a proposed Akka-to-Pekko move, ask them to inspect artifact coordinates, configuration changes, serialization, persistence plugins, and cluster compatibility. Treat migration as a tested engineering change; technical suitability and your organization's review of dependency terms are separate considerations.
- How does matching work for a specialized Scala role?
- Start with a 15-minute call and describe the exact mix of Scala version, libraries, JVM runtime, and production responsibilities. Most teams interview matched engineers within a week of that call. If the fit is not right, we bring in a replacement with a proper hand-over, including build instructions and context for the Scala work in progress.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
