Sound familiar?
- Hiring a senior Data Engineering developer full-time is taking months.
- Your Data Engineering 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 data engineers from NextGen Coding Company to join your team on Python pipelines, Airflow orchestration, dbt transformations, and warehouse development. Every engineer lives and works in the US, with no offshore subcontracting. Define the assignment around your actual bottleneck: unreliable ingestion, slow Snowflake queries, inconsistent BigQuery models, or a reporting layer that changes whenever an upstream schema shifts.
For a useful match, bring your source systems, warehouse choice, orchestration setup, and the operational problems your team needs to resolve. A PostgreSQL-to-Snowflake pipeline using Debezium has different requirements from batch ingestion into BigQuery or Spark processing on Databricks. Our engineers work your hours and join your standups; NDA and full IP assignment are signed before anyone touches your code.
Frequently asked questions
- Should I hire a data engineer or an analytics engineer for dbt?
- Choose a data engineer when the work centers on ingestion, orchestration, storage, or pipeline reliability. An analytics-focused assignment is more appropriate for dbt models, metric definitions, and reporting datasets. If your backlog spans both, describe the source-to-dashboard workflow so the engineering interview can test Python, SQL, warehouse design, and dbt together.
- What should I ask an Airflow developer in an interview?
- Ask how they make tasks idempotent, handle retries without duplicating records, and backfill historical data without overwhelming source systems. Have them explain scheduling behavior, task dependencies, and secrets management. Discuss your deployed Airflow version explicitly: an Airflow 2.x maintenance assignment and an Airflow 3 migration require different compatibility checks and rollout planning.
- Can a data engineer improve slow Snowflake or BigQuery workloads?
- Start with query profiles, table layout, workload patterns, and the transformations feeding the slow queries. In Snowflake, examine pruning, clustering needs, and warehouse configuration; in BigQuery, review partition filters, clustering, and scanned data. The assignment should include correctness checks and representative query benchmarks, rather than promising improvements before anyone inspects the workload.
- How should we evaluate experience with Kafka and change data capture?
- Use a scenario involving PostgreSQL changes captured through Debezium and delivered into Kafka. Ask about schema evolution, duplicate events, deletes, ordering, and recovery after connector downtime. Strong answers should distinguish delivery guarantees from end-to-end correctness and explain how reconciliation detects missing records before downstream dbt models or business reports become unreliable.
- How quickly can we interview a US-based data engineer?
- Most teams interview matched engineers within a week of the first call. Book a 15-minute call and bring your stack, source volume patterns, pipeline ownership expectations, and the problems behind the hire. For a data engineering interview, prepare a sanitized DAG, SQL model, or ingestion failure scenario rather than sharing production credentials.
- 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.
