About INDY

INDY powers every operational layer of a movie theater—from ticket sales and concessions to scheduling, accounting, and real-time business intelligence. Our platform handles tens of millions of tickets a year across cinemas worldwide, yet we remain a nimble team where each engineer’s work is felt immediately in theaters on six continents.

Why This Role Exists

Our home-grown reporting platform is the analytical backbone of INDY. It decomposes incoming queries into thousands of parallel Sidekiq jobs (hourly → daily → weekly → monthly roll-ups) and serves the results back to cinema managers in seconds. As volume soars, we need a backend-focused engineer to:

  • Own and harden this distributed reporting engine.
  • Design data pipelines that can ingest years of transactional data and still answer ad-hoc questions quickly.
  • You will partner with—but not be accountable for—front-end engineers who wire these APIs into Vue-based dashboards.

What You’ll Do

  • Architect & Scale
    • Profile, partition, and optimize multi-terabyte MySQL schemas.
    • Tune Sidekiq queues, worker pools, and EC2 autoscaling groups for bursty loads.
    • Refactor long-running jobs into idempotent, parallelizable units.
  • Maintain Data Integrity & Observability
    • Implement validation, audit trails, and automated backfills.
    • Instrument metrics/alerting around throughput, latency, and cost.
  • Expand Administrative Workflows
    • Expose clean GraphQL/REST contracts that power accounting tools for film bookings, revenue splits, and studio payouts.
    • Introduce domain-specific abstractions (DSLs, helpers) so other engineers can add new report types rapidly.
  • Collaborate Across Functions
    • Work with infra engineers on Terraform-managed AWS resources.
    • Pair with front-end devs to ensure APIs are ergonomic and secure.
    • Advise product and finance teams on data-model trade-offs.

What We’re Looking For

Must-Have

  • 5+ yrs building high-throughput backend systems
  • Deep Ruby/Rails & ActiveRecord expertise
  • Hands-on MySQL tuning (indexes, partitioning, query plans)
  • Proven record scaling background-job frameworks (Sidekiq, Resque, Celery, etc.)
  • AWS production experience (EC2, RDS, IAM, VPC)

Nice-to-Have

  • Experience with BI/reporting engines or OLAP stores
  • Exposure to ClickHouse/Redshift/BigQuery
  • Event-driven or stream processing (Kafka, Kinesis)
  • Familiarity with data-viz pipelines (we use Highcharts.js)
  • Contributions to OSS or tech-blog posts on performance

What Success Looks Like (6-12 Months)

  • Daily report-generation latency cut by 50 % while data volume doubles.
  • Zero-downtime schema migrations and automated backfill strategy in place.
  • First phase of studio-settlement APIs shipped and adopted by finance ops.
  • Comprehensive dashboards/alerts proactively surface scaling limits before customers notice.

Why INDY Rocks

  • Massive Visible Impact – Your optimizations ripple out to millions of moviegoers.
  • Start-to-Finish Ownership – No layers of bureaucracy; ship, measure, iterate.
  • Technically Spicy – Distributed computing meets real-world financial correctness.
  • Tight-Knit Crew – Collaborate directly with founders and domain experts.
