"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."

Sound familiar?
- Hiring a senior Elixir developer full-time is taking months.
- Your Elixir 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.

Hire US-based Elixir developers from NextGen Coding Company for Phoenix applications, LiveView interfaces, and OTP services. Build your hiring brief around the system you actually run: Phoenix 1.7 or 1.8, LiveView 1.x, Ecto with PostgreSQL, or background processing with Oban. All our engineers live and work in the US, and we do not use offshore subcontracting.
Elixir hiring should test supervision design, database behavior, and production debugging, not just familiarity with functional syntax. Your project may involve reconnecting LiveView sessions, controlling job concurrency, diagnosing mailbox growth, or deploying clustered BEAM nodes. Our engineers are senior, and many have more than ten years of engineering experience. They work your hours and join standups; start with a 15-minute call to define the role.
Frequently asked questions
- What should I ask an Elixir developer in a technical interview?
- Ask how they would structure a supervision tree, recover from a failing process, and distinguish transient state from durable data. Include an Ecto query review and a production debugging scenario involving a busy GenServer. Strong answers should explain failure boundaries and observability, not assume that lightweight processes eliminate database contention or other system bottlenecks.
- Is Phoenix LiveView suitable for my application?
- LiveView is worth considering for interactive dashboards, administrative tools, and forms where server-managed state fits the product. Evaluate connection reliability, latency, accessibility, and the amount of browser-local interaction required. A developer should be able to explain when LiveView hooks are sufficient and when a separate JavaScript interface would be a better boundary.
- Can an Elixir developer improve Oban job reliability?
- Scope the work around queue configuration, retry behavior, idempotency, and visibility into failures. Oban runs on PostgreSQL, so database capacity and transaction boundaries matter alongside worker code. Ask how duplicate execution is handled when a job calls an external service, and how operators can inspect, retry, or cancel work without introducing inconsistent application state.
- How do I evaluate experience deploying Phoenix and OTP applications?
- Look for practical knowledge of Mix releases, runtime configuration, graceful shutdown, and database migrations. If clustering is required, discuss node discovery and behavior during network partitions rather than assuming distributed Erlang solves availability automatically. Telemetry instrumentation, structured logs, and deployment rollback plans should be part of the conversation, alongside your specific hosting environment.
- Will an Elixir developer work directly with our existing team?
- Our engineers work the client's hours and participate in standups rather than handing work across an offshore schedule. Before anyone touches your Phoenix or OTP codebase, we sign an NDA and full IP assignment. Use the first call to outline repository structure, code review expectations, deployment access, and the Elixir responsibilities your team needs covered.
- 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.
