About the Role
We are looking for excellent Software Engineers who can design challenging software engineering tasks to train AI models. Each task should require a minimum of 1.5 hours -2 hours of screen recording to complete and must use VS Code along with at least one of the approved tools listed below. After proposing the task, and getting the approval on the same, you will complete it while recording your screen and explaining your thought process throughout the implementation.
Responsibilities
- Propose complex software engineering tasks that require at least 1.5 hours to complete.
- Complete the proposed task while recording your screen and explaining every step.
- Use VS Code along with at least one of the approved tools listed below.
- Deliver a minimum of 6 hours of approved screen recordings per day.
- Spend approximately 2–3 hours per day creating high-quality task proposals.
- Deliver 150+ hours of approved recordings per month.
- Follow all project guidelines and quality standards.

Example Task Proposal
Task 1: Configurable Async Rate Limiter with Token Bucket, Circuit Breaker, and Observability
Implement a production-style asynchronous rate-limiting framework for an HTTP client that enforces configurable per-host concurrency and request-rate limits while remaining resilient to transient service failures. The implementation must be driven entirely by a provided configuration specification, support retries with exponential backoff and jitter, expose structured metrics and logs, and include a comprehensive automated test suite validating concurrency limits, retry timing, circuit-breaker behavior, and overall throughput.
Workflow:
A configuration specification document describing per-host limits (maximum concurrent requests, requests-per-second, retry policy, exponential backoff formula with jitter, and circuit-breaker thresholds).
A high-level architecture/design note describing the intended request processing pipeline, component responsibilities, and interactions between the scheduler, token bucket, retry handler, circuit breaker, logging, and metrics modules.
A mock dataset of 20-50 API endpoints spanning multiple hosts (e.g., api-a.local, api-b.local, api-c.local).
A configurable fakeRequest(url) implementation that simulates:
- Variable latency (100-500 ms)
- Random transient failures (~20%)
- Host-specific failure patterns
- Configurable timeout scenarios
An intentionally incomplete HTTP client codebase that currently performs unrestricted asynchronous requests without rate limiting. The supplied implementation contains only the basic project structure, and requires completing multiple interdependent components including configuration parsing, token-bucket rate limiting, retry scheduling, circuit-breaker state management, metrics collection, structured logging, and portions of the automated test suite before the application functions correctly.
Challenge Dimension:
Cross-source reasoning by requiring the solver to reconcile behavior described across the configuration specification, architecture/design note, incomplete codebase, and timing-based automated tests.
Multi-item state tracking by coordinating concurrent request execution while simultaneously tracking per-host concurrency, retry attempts, token availability, circuit-breaker state, and request completion across multiple hosts.
Deliverable:
The completed submission should include:
Source implementation of the configurable asynchronous rate limiter.
Configuration file(s) implementing the supplied specification.
Automated unit and integration test suite.
Structured logging output from a representative execution.
Metrics output (JSON or console report).
A short implementation summary (3-5 lines) describing the architecture and key design decisions.
