Facts

Purpose
SignalLoop is an AI-native candidate evaluator for software engineering hiring that assesses realistic backend tasks with a constrained AI collaborator.github.com · 9 Oct 2026
Evidence report
The platform captures evidence of candidate framing, AI usage, verification behavior, design judgment, and ownership, then generates an Engineering Evidence Report for employer review.github.com · 9 Oct 2026
Candidate workspace
Candidates use invite links and a browser workspace with a Monaco editor for file editing.github.com · 9 Oct 2026
Testing
Candidates can run public tests through a local Docker worker, and final submissions run hidden tests through the worker.github.com · 9 Oct 2026
AI provider
The constrained AI collaborator supports an OpenAI provider and a local fallback.github.com · 9 Oct 2026
Employer advisory
An optional bounded GPT-5.6 advisory summarizes allowlisted process evidence without changing deterministic scores, integrity labels, or recommendations.github.com · 9 Oct 2026
Role matching
Guided role matching maps role or job-description requirements to the closest registered Standard or Advanced FastAPI assessment and reports unsupported coverage.github.com · 9 Oct 2026
Integrations
The hosted pilot uses Render, Supabase, and Clerk, with optional AWS ECS/Fargate per-run execution for operators configuring isolated production infrastructure.github.com · 9 Oct 2026
Security controls
Pilot hardening includes audit events, validation and fallback error responses, retry-bounded hidden-worker calls, and basic rate limiting.github.com · 9 Oct 2026
Deployment options
The project documents a hosted Render/Supabase/Clerk pilot and local setup using PostgreSQL, a Docker worker, an API, and a web app.github.com · 9 Oct 2026
Notable limitation
Guided role matching does not assemble new questions, and question-bank items are not connected to employer blueprint composition, mixed-question delivery, or report scoring.github.com · 9 Oct 2026
Production use
The repository says its public demo assessment packs expose hidden tests, scoring rubrics, and evaluator notes, and recommends private calibrated packs for real hiring decisions.github.com · 9 Oct 2026
Maintainers
SignalLoop was created as joint work by Sreenivas Makam and Ritesh Dhoot.github.com · 9 Oct 2026
Product
SignalLoop is an AI-native candidate evaluator for software engineering hiring.github.com · 9 Oct 2026
Assessment
It evaluates candidates solving backend engineering tasks with a constrained AI collaborator and generates an Engineering Evidence Report for employer review.github.com · 9 Oct 2026
Evidence captured
It captures evidence of problem framing, AI use, verification, design judgment, and candidate ownership.github.com · 9 Oct 2026
AI providers
The constrained AI collaborator supports an OpenAI provider and a local fallback.github.com · 9 Oct 2026
Employer reporting
The platform generates deterministic Engineering Evidence Reports, with an optional bounded GPT-5.6 advisory that does not change scores, integrity labels, or recommendations.github.com · 9 Oct 2026
Security status
The security policy describes SignalLoop as a pilot-stage hiring evaluation system and a reference implementation rather than a hardened production SaaS.github.com · 9 Oct 2026
Security boundaries
The policy says candidate invite tokens are bearer links, public demo hidden tests and rubrics are unsuitable for real hiring, and manual evaluator review is required before hiring decisions.github.com · 9 Oct 2026
Execution isolation
The security policy says local execution uses Docker and hosted production execution should use isolated per-run tasks.github.com · 9 Oct 2026
Open-source license
The repository states that original application code and documentation are Apache-2.0 unless a file specifies otherwise, while imported question-bank content retains upstream licensing and attribution requirements.github.com · 9 Oct 2026
Notable limit
Guided role matching does not compose new questions, and the question bank is not connected to employer blueprint composition, candidate delivery, or report scoring.github.com · 9 Oct 2026
Intended users
The product is for software engineering hiring teams evaluating candidates’ problem framing, verification, judgment, AI collaboration, and ownership.github.com · 9 Oct 2026
