A laboratory, not an agency
Most technical staffing firms operate as routing layers. They receive a job description, broadcast it across a sourcing network, lightly screen the inbound, and hand you whatever survives the noise. TechHire Labs operates as a laboratory. Every requisition we accept begins with a discovery session in which we walk through your architecture diagrams, deployment topology, and the actual failure modes your team has absorbed in the last twelve months. From that we construct a sandbox — a controlled replica of the surface area your future hire will own — and we use that sandbox to grade every candidate before you ever see their name.
Our staff is intentionally small and intentionally senior. The people grading kernel engineers have shipped kernels. The people grading distributed systems engineers have been on call for control planes. Vetting at this layer cannot be outsourced to a keyword scanner or a junior coordinator; it requires peers, and we provide them.
What the sandbox actually does
When you submit a brief, our intake engineers translate it into a sandbox manifest — language version, build toolchain, observability stack, simulated load profile, fault schedule, and the specific surface area the new hire will operate. The manifest spins up an isolated environment with synthetic services, traffic generators, and a telemetry pipeline that captures every move a candidate makes inside it.
Candidates we have already pre-graded are dropped into your sandbox and given a real assignment: a regression to chase, a contention to resolve, a syscall path to harden, a budget to instrument. We do not watch over their shoulder. We watch the artifacts — commits, traces, profiler output, design notes — and we score against a rubric you helped us build. The result is not a yes-or-no signal. It is a packet: the work, the telemetry, the rubric, and a written assessment from a senior reviewer.
Who we are
TechHire Labs is operated by former staff engineers from autonomous vehicle programs, kernel teams, and hyperscale infrastructure groups. We were the people writing the interview loops that nobody could pass and watching the offers we extended get countered by FAANG. We built TechHire Labs because we wanted to stop running the same broken loop for the next company we joined. Today we run that loop on behalf of our clients, and we run it once, properly, at the front of the process — not five times over six weeks at the back.
What we will not do
We will not send you resumes we have not graded. We will not pad shortlists with "stretch" candidates to look productive. We will not pursue requisitions we cannot sandbox honestly — if we cannot build the environment, we will tell you, and we will recommend a different partner. The discipline of the laboratory works only when it is applied without exception.
