Staff augmentation is the model where you add vetted senior engineers directly to your own team, under your management and your process, instead of outsourcing a project or waiting out a hire. Cubitrek staffs full-stack, AI and ML, agent-framework, mobile, DevOps, data, and security engineers this way, on monthly billing per engineer, replaceable at any time. 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, and is expected to know where it helps and where it quietly does not.

What we ship

Everything under one roof.

  • 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).

    Trigger
    Every keystroke in the engineer's editor.
    Output
    Fewer lines written by hand, more focus on architecture and judgment.
  • Standup reporter

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

    Trigger
    Every morning at the engineer's local standup time.
    Output
    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.

    Trigger
    When a ticket is assigned to the engineer.
    Output
    A broken-down plan with risks and unknowns surfaced before code is written.
  • Documentation writer

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

    Trigger
    Every merged PR.
    Output
    Docs that match the code on day one and stay current.
  • Code-review agent

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

    Trigger
    On every PR open or update.
    Output
    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

How the work actually runs.

  1. 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.

  2. 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.

  3. 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.

  4. 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.

Questions buyers ask us.

  • No recruiter margin, no bench-seller incentive, no marketplace markup. You work directly with our delivery lead; our engineers are long-tenured Cubitrek team members, not marketplace contractors trying to move to the next gig. We also bundle our internal agent toolbox (pair programmer, standup reporter, spec reader, documentation writer, code-review agent) at no extra cost. We do not put a multiplier on it: the published research is clear that these tools help on some tasks and slow experienced people down on others, and knowing which is which is the part we hire for.
  • Three tiers: Mid-senior (3-5 years experience), Senior (5-8 years, lead-capable) and Principal (8+ years, specialty expertise in AI, SRE, or security). Monthly billing, no minimum commitment beyond the first month. Seniority and specialization drive the rate, not negotiation theater. We quote after a short scoping call.
  • 7 days median, 3 days fast-path when we have a current bench match. Brief on Monday, shortlist Wednesday, interview Thursday, contract Friday, embedded the following Monday. Slower when the role requires very narrow specialisation (rare framework, hard compliance overlay, niche industry experience), but we are transparent about that on the brief call.
  • EU and US working hours by default. Pakistan time zone for back-office or follow-the-sun coverage where it makes sense. Most engineers shift their day to overlap with the client's core hours; we screen for this on the candidate interview before the client ever sees the shortlist.
  • Yes. The first two weeks are a soft start. If the fit is not right (technical, cultural, communication, anything), we replace the engineer at no cost. The replacement candidate ships within 5 business days. Most engagements pass the two-week mark without a replacement; the soft start is insurance, not a normal path.
  • You, 100%. IP assignment is done contractually before day one, covered under the master services agreement. Everything the engineer writes during the engagement is your intellectual property: code, designs, documentation, ML models, prompts, eval data. No surprises, no shared-IP fine print.
  • Yes. Common pattern for series-B and -C startups that need a full squad against a 3-6 month deliverable. We staff a delivery lead, 2-4 engineers, a designer, and a PM under the same monthly billing model. Same vetting standard across all roles, same replace-anytime policy.
  • Yes, by default. Every engineer we place has shipped at least one production agent (LangChain, CrewAI, AutoGen, OpenClaw, or hand-rolled). They use the Cubitrek agent toolbox (pair programmer, code reviewer, spec reader, documentation writer, standup reporter) from day one. If your stack needs deeper AI/ML specialisation (RAG pipelines, fine-tuning, model ops), we route you to the AI engineer tier specifically.
  • Engineers on the Senior or Principal tier ship on-call ready. We support primary on-call rotation when the client's on-call infrastructure includes the engineer; secondary on-call as a backup; or 24/7 follow-the-sun coverage when the team is distributed enough to rotate naturally. Pricing for on-call is bundled into the monthly rate up to a reasonable cap.
  • 30-day notice on any engagement. No cancellation fee, no contract escape clause. Engineers transition back to the Cubitrek bench or onto another client. We do not charge for engineers you do not need, and we do not lock you into multi-quarter commitments.
  • Yes. Standard engagements ship with NDA, mutual MSA, IP assignment, and our SOC 2 Type II attestation. GDPR-compliant for EU clients. HIPAA-aligned for healthcare clients (we have BAAs ready). ITAR and other US-export-controlled engagements are handled case-by-case via our US legal entity.
  • Yes. That is a different service: Cubitrek delivery (fixed-scope project with our PM running it) instead of staff augmentation (engineers embedded in your team under your management). Both run from the same engineering pool with the same vetting. The right choice depends on whether you want to own the project management or hand it off.
