Staff augmentation

On-demand developers, ready in days, not months.

Pre-vetted senior engineers who plug into your team. Hourly, part-time, or full-time. Full-stack, mobile, AI / ML, DevOps, cloud, QA. You stay in control. We supply the people.

Most engagements start within a few days of the brief. No 90-day onboarding. No agency middle layer between you and the engineer doing the work.

Hire only the capacity you need.

Staff augmentation extends your existing team with skilled engineers from OST. Use it when full-time hires take too long, when you need a specialist for one stretch of the roadmap, or when capacity has to flex around launch dates.

01 · Scale on demand

Add capacity for a sprint, a quarter, a year.

Bring on engineers when the roadmap needs to move faster than hiring can support. Release them, or roll them into long-term retainers, when the surge ends. No severance, no benefits overhead, no recruitment cycle.

02 · Bridge skill gaps

Get the specialist your team is missing.

Need a senior Drupal architect, a React Native lead, a Salesforce developer, an MLOps engineer? Pull a person who has shipped that stack ten times before. Pay for the niche skill without committing to it on payroll.

03 · Keep control

Your roadmap, your tickets, your standups.

Augmented engineers report into your tech lead. They use your sprint board, your pull-request workflow, your code review standards. We supply the people. You manage the work.

04 · Cut delivery cost

Skip recruiting, training, and bench cost.

You bypass agency markups on full-build projects, full-time hire ramp time, and the cost of keeping rare specialists on payroll between needs. Pay only for the hours you book.

Three engagement models. Pick what fits.

Match the engagement to the work. Hourly for short fixes and overflow. Part-time for ongoing, predictable load. Full-time for embedded contributors on multi-quarter roadmaps.

Model A

Hourly

For short fixes, spike work, code review, audits, urgent feature drops.

  • Commitment No minimum hours
  • Billing Tracked & logged
  • Onboarding Same week
  • Best for Bursts & specialists

Pay only for hours worked. End anytime.

Model B

Part-time

For steady, ongoing capacity at 20 to 30 hours per week. The most common model for product teams.

  • Commitment Monthly retainer
  • Hours 20 to 30 / week
  • Onboarding 3 to 7 days
  • Best for Long projects

Predictable cost, predictable output.

Model C

Full-time

Dedicated 40-hour engineer embedded in your team. Behaves like a hire without the hiring.

  • Commitment Multi-month
  • Hours 40 / week
  • Onboarding 3 to 10 days
  • Best for Embedded squads

Lowest blended rate. Highest continuity.

Why teams choose OST for augmentation.

Senior staffing without bait-and-switch. Compliance and security on day one. Continuity beyond the contract. The same team that delivers full builds is on the bench you draw from.

No swaps

The engineer in your interview is the engineer in your standup.

The senior on your kickoff call is the senior on your release. We do not bait you with seniors and ship juniors. If a profile is unavailable mid-engagement, you approve the replacement. Always.

Pre-vetted

Engineers come from our delivery bench, not a freelance pool.

Every developer has shipped real production work for OST clients. Background-checked, NDA-ready, code review trained. No freelance marketplace surprises.

Compliance ready

HIPAA, GDPR, SOC 2, FedRAMP-aligned.

For regulated stacks (healthcare, government, financial services), we staff engineers with the right training and the right paper trail. SBOM, audit logs, attestations on request.

USA & India coverage

Lansdale PA, Atlanta GA, plus India delivery team.

US-based PMs and senior architects when you need them on your time zone. India delivery team when economics and after-hours coverage matter. We blend both transparently inside one engagement.
