Python Backend Developer Beats (CI Dashboard)
RingCentral
Say hello to possibilities.
It’s not every day that you consider starting a new career. We’re happy that someone as talented as you is considering this role. RingCentral is a $2 billion global leader in cloud-based communications and collaboration software. We are fundamentally changing the nature of human interaction—giving people the freedom to connect powerfully and personally from anywhere, at any time, on any device.
Beats (CI Dashboard) is a system that ingests CI automation results (around 100,000+ tests per night), aggregates them, and produces rich analytical reports for Engineering and QA teams.
The PlanIT team is taking ownership of the product: you’ll maintain the current implementation and evolve the architecture to meet new requirements.
This role requires on-site presence at our office 4 days a week to support effective collaboration and teamwork.
Key responsibilities
Develop and maintain the Python backend for the CI Dashboard under high-load conditions (large data volumes, intensive writes/aggregations, heavy reporting queries).
Work with an existing codebase: quickly understand “someone else’s” code, identify bottlenecks, make safe changes, and reduce technical debt.
Design and implement improvements focused on performance and efficiency (CPU/memory/IO), speeding up nightly processing and report generation.
-
Drive an evolutionary redesign (“moving the system onto new rails”):
refactor critical modules without disrupting production,
improve the data processing pipeline architecture,
increase reliability and observability.
Own data model and storage efficiency: schemas, indexes, partitioning, query optimization, caching.
Strengthen engineering quality: tests, code reviews, standards, technical documentation; participate in planning and estimation.
Requirements:
Strong Python backend experience (3+ years).
Hands-on experience with high-load systems; ability to reason about typical hotspots (DB, network, serialization, locks, GC, etc.) and fix them.
-
Solid profiling and performance optimization skills:
latency/throughput diagnosis,
application + database bottleneck analysis,
optimizing hot paths.
Strong SQL/PostgreSQL skills, including query tuning (EXPLAIN, indexes, partitioning).
Understanding of distributed systems and reliability practices: retries, idempotency, backpressure.
Experience maintaining and evolving large existing/legacy codebases; careful migrations and backward compatibility.
Familiarity with observability: metrics/logs/traces, alerting, incident investigation
Nice to have
Kafka / queues / stream processing (especially for high-volume CI result ingestion).
ClickHouse / columnar stores or experience building analytics data marts.
Caching strategies (Redis), pre-aggregation, materialized views.
Docker/Kubernetes, CI/CD, performance/load testing.
Experience building reporting/analytics platforms: time-series, drill-down, filters/aggregations, deduplication, historical runs storage.
What success looks like
You ramp up quickly, become an owner of critical areas of the codebase, and confidently improve them.
You reduce processing/report generation time and improve stability as load grows.
You propose a clear, low-risk, phased architecture evolution plan and start executing it.
What we offer:
Well-coordinated professional team.
Cutting edge technologies, interesting and challenging tasks, dynamic project, great opportunities for self-realization, professional and career growth.
Additional Health and Life Insurance Package.
Employee Assistance Program.
25 vacation days.
102,26 EUR/200 BGN Digital Food Vouchers
61, 36 EUR/120 BGN Gross as part of the salary for Working Expenses Allowance
