from this employer's Department of Labor filings
Third-party placement is common here
100% of this employer's visa filings place the worker at a client company rather than at the employer itself, across 48 clients. Your visa, salary band and layoff exposure would follow the employer of record, not the client.Most common: Wells Fargo · Telecommuter to Floor & Decor · Telecommuter to Canon USA IncFiles as an H-1B dependent employer.
Green-card follow-through: 100%
Of 6 labor certifications old enough to have been used, 0 expired without the employer filing the next step. Median time from filing to decision: 484 days.100% of their filings were for a worker who already held the job.Only certifications past the 180-day window are counted — recent ones cannot have expired yet.
Files H-1B transfers
12 transfer filings in the last year, covering 12 workers. Median labor-condition decision: 7 days. An employer that already files transfers is one that can take over an existing H-1B.

About the role
- What We Expect End-to-End Ownership - Own features from design -> development -> testing -> deployment -> production support - Take accountability for the reliability and performance of your services in production - Drive technical decisions without waiting to be told what to do System Design & Architecture - Design scalable, resilient distributed systems handling millions of daily transactions - Make pragmatic trade-off decisions (consistency vs. availability, complexity vs. speed) - Produce clear technical design documents and lead design reviews - Evaluate build vs. buy decisions with data Development - Strong proficiency in Java and/or Scala - Build high-throughput, low-latency microservices - Write clean, maintainable code - but more importantly, know when and what to build Testing & Quality - Write meaningful unit, integration, and contract tests - not just for coverage metrics - Own E2E test strategy for your services - Build confidence in deployments through automated validation Infrastructure & Cloud (AWS) - Hands-on with AWS services (ECS/EKS, Lambda, S3, SQS, CloudWatch, IAM) - Understand networking, security, and cost implications of architectural choices - Comfortable with Infrastructure as Code (Terraform/CloudFormation) Data & Messaging - Kafka - design event-driven architectures, manage topics, handle consumer lag and rebalancing - Redis - caching strategies, pub/sub, cluster management - MongoDB/DocumentDB - schema design, indexing, query optimization, aggregation pipelines Monitoring & Observability - Datadog - build dashboards, set meaningful alerts, track SLOs, analyze APM traces - Splunk - log analysis, search queries, correlation across services for incident investigation - Understand distributed tracing, structured logging, and metric-driven decision making SRE Mindset - Analyze production incidents: read logs, trace requests, identify root cause under pressure - Think about failure modes before they happen (circuit breakers, retries, fallbacks, graceful degradation) - Participate in on-call rotations and drive blameless post-mortems - Proactively identify capacity risks and performance bottlenecks Proactive Analysis & Innovation - Identify risks, tech debt, and performance bottlenecks before they become incidents - Propose and drive improvements - don''t wait for a ticket - Stay current with industry trends and bring relevant ideas to the team - Challenge existing patterns when they no longer serve the system What This Role is NOT - A pure coding role - AI can write code; we need engineers who decide what to build and why - A ticket-taker role - you identify work, not just execute it - A siloed role - you''ll collaborate across teams, influence architecture, and mentor others Nice to Have - Experience with circuit breaker patterns (Hystrix, Resilience4j) - Performance tuning at scale (JVM, thread pools, connection pools) - Experience with CI/CD pipelines and deployment strategies (blue-green, canary) - Contributions to internal tooling or developer experience improvements - Experience leading technical initiatives across multiple teams
Responsibilities
- You''ll be responsible for the full lifecycle of backend services: from design and development through production reliability.
- In an era where AI can generate code, we value engineers who think critically, anticipate problems, and drive systems forward.
