Job Description

Program Overview

Tech Sur Solutions is supporting a federal program delivering a modern, cloud- application for a Department of Defense end-user community. The application replaces legacy paper-based workflows with a digitized, mobile-first platform deployed on Google Cloud Platform (GKE) within an IL4 authorization boundary. The technology stack includes Angular, Spring Boot (Java), Postgre

SQL (Cloud SQL), and a Git Lab-managed CI/CD pipeline.

Position Summary

We are seeking a Senior Load & Performance Test Engineer to join our test automation team supporting a high-visibility DoD modernization program. This role carries primary technical ownership of all load and performance testing activities — including Green Doc / RSO approval stewardship — using Grafana k6 OSS. The candidate will also contribute to automated functional testing (Playwright) and unit testing, but the core responsibility — and the reason this position exists — is to design, develop, execute, and report on load and performance tests in a federal cloud environment.

Primary Responsibilities:
Load & Performance Testing (k6) — ~60–70% of Time (target)

· k6 Script Development & Execution:
Author, maintain, and execute load and performance test scripts in JavaScript/Type Script using Grafana k6 OSS. All scripts must be version-controlled alongside application source code.

· Test Scenario Design & Orchestration:
Design and execute load profiles including baseline/steady-state, peak business load, stress ramp to SLA-breach identification, and soak/endurance testing (spike testing only if authorized under a future Green Doc amendment).

· Transaction Mix Configuration:
Define and manage parameterized transaction mixes across inquiry, create/update, reporting, and administrative operation classes — refining based on stakeholder input and production usage patterns.

· Threshold & SLO Definition:
Define SLIs/SLOs and collaborate with SRE and product stakeholders to set and evolve performance thresholds that govern automated run pass/fail.

· Performance Diagnostics:
Root-cause regressions across the stack — JVM/GC, Postgre

SQL query plans, GKE autoscaler and pod-level resource behavior — not just report them.

· Cloud Infrastructure & Deployment:
Deploy k6 as a containerized workload (Nix-flake-built image) within GKE, or as a managed VM for manual verification. Work directly with partner cloud/infrastructure engineers on:

o VM provisioning, workload-/service-account configuration, and IAM role assignments

o Artifact Registry management and k6 image provisioning

o GCP Secret Manager integration for test user credentials

o Pipeline-triggered execution via Git Lab Runner

· Authentication Strategy:
Manage
-provider-based authentication for load-test service accounts, including session management, account-lockout mitigation, and explicit login/logout sequences. Coordinate with partner teams for test user provisioning.

· CI/CD Integration & Execution Governance:
Integrate k6 tests into the Git Lab pipeline so load runs execute automatically on successful builds/deploys, with environment guards, protected variables, and safeguards against accidental execution against demo/.mil/prod.

· Observability & Reporting:
Stream k6 results to the enclave-internal Grafana / Prometheus stack (no external telemetry egress). Define metrics, compile load-testing reports, and present findings to program stakeholders.

· Browser-Based Load Testing:
Develop and execute browser-based load testing scripts using k6/browser against Angular frontend endpoints.

· Data Integrity & Recovery:
Collaborate with infrastructure engineers on Cloud SQL snapshot/restore strategies before and after…
