Hiring senior engineers in-house takes quarters and burns $21k to $38k per month fully loaded. Our staff augmentation services embed pre-vetted senior engineers into your team in a week, at a quarter of the cost, with no recruiter or middle-layer taking a cut. Every engineer also gets our agent toolbox so they ship 2 to 3x the old pace.

What we ship

Everything under one roof, delivered by senior operators.

Full-stack engineers

Next.js, React, Node, Python, Go, TypeScript. Senior developers who ship production code with tests, observability, and documentation that matches reality.

AI and ML engineers

LLM engineering, RAG pipelines, embedding strategy, model ops, eval harnesses, fine-tuning. Engineers who have shipped GPT, Claude, Gemini, and open-source models into production.

Agent framework engineers

LangChain, LangGraph, CrewAI, AutoGen, OpenClaw, and MCP-native agent development. Engineers who have shipped autonomous agents to revenue teams, not just prototypes.

Mobile engineers

Swift, Kotlin, React Native, Flutter. Pre-vetted senior mobile talent who can ship to the App Store and Play Store without surprises in the review process.

DevOps and SRE

AWS, GCP, Azure, Kubernetes, Terraform, Pulumi. On-call-ready engineers who can stand up production infrastructure and own the pager when it goes off.

Data engineers

Warehousing (Snowflake, BigQuery, Redshift), dbt, real-time pipelines (Kafka, Flink), and the LLM-augmented analytics stack that lets the rest of the team self-serve.

Security engineers

AppSec, SOC 2 readiness, pentesting, zero-trust implementations, prompt-injection defense for agent workloads. The skill set most teams need but cannot hire fast enough.

Technical leads

Staff-level engineers who can architect, code-review, mentor your team, and own delivery across multiple workstreams. The hire that usually takes 6 months to find in the open market.

Whole pods

Need a 4-person squad (PM + 2 engineers + designer) instead of one engineer? We staff full pods with a delivery lead, same vetting standard, same monthly billing.

AI in the loop

The agents that sit next to the engineers you hire.

Every engineer we place comes with the same agent toolbox our own teams use. You do not just get a senior. You get a senior who ships at 2 to 3 times the old pace because half the production grind is now agent-driven.

Pair programming agent

Real-time code completion, refactors, and test scaffolding inside the IDE (Cursor, VS Code, Zed, JetBrains).

Fewer lines written by hand, more focus on architecture and judgment.
agent 02

Standup reporter

Summarizes yesterday's commits, PRs, blockers, and merged work for your team chat.

triggerEvery morning at the engineer's local standup time.
A short, skimmable update so your PM never has to chase.

Spec reader

Parses your Notion, Linear, GitHub, or Jira specs into implementation checklists with open questions flagged.

A broken-down plan with risks and unknowns surfaced before code is written.
agent 04

Documentation writer

Produces ADRs, READMEs, runbooks, and changelogs directly from merged code.

triggerEvery merged PR.
Docs that match the code on day one and stay current.
agent 05

Code-review agent

Pre-reviews every PR for style, security, performance, and missing tests before a human reviewer sees it.

triggerOn every PR open or update.
Inline comments with suggested fixes. Frees senior reviewers to focus on architecture.
You pay for the engineer. You get the engineer plus the agent stack at no extra cost.
How we work

A four-stage cadence that compounds every sprint.

01

Brief

Tell us role, stack, seniority, and timezone. Written job spec back in 48 hours with the candidate pool sized and the shortlist plan agreed.

02

Match

Two to three senior candidates delivered within 3 to 5 business days. Each candidate ships with a written work sample, a recorded technical walkthrough, and reference notes.

03

Interview

You run the technical interview. We handle contracts, payroll, compliance, IP assignment, and onboarding. First two weeks are a soft start: if it is not a fit, we replace at no cost.

04

Operate

Your engineer shows up on day one fully integrated (Slack, email, repo access, on-call rotation if applicable). Monthly billing. Replace anytime. Delivery lead checks in monthly to make sure the engagement is compounding.

< 7 days
median time to embed
Series-B fintech needed two senior backend engineers (Go + Postgres) for a 6-month build. Brief on Monday, two candidates Wednesday, contracts signed Friday, engineers fully embedded the following Monday. 7-day end-to-end. The same hires through their previous recruiter took 14 weeks each.
-60%
cost vs in-house US senior
Mid-market SaaS replaced a churned US-based senior AI engineer ($28k/mo fully loaded) with a Cubitrek-staffed senior AI engineer at $3,500/mo. Same seniority, EU timezone overlap, MCP + LangChain experience, started in 9 days. 12-month savings: $294,000 with no productivity loss on the team.
94%
retention at 12 months
Across 47 engineers placed in the 12 months ending Q1 2026, 44 are still embedded with the same client. The 3 transitions were one client downsize, one engineer family move, and one role-fit mismatch we resolved with a no-cost replacement. We track this monthly because durable embeds beat fast embeds every time.
