GR8_TECH builds B2B iGaming platforms for operators who play to lead.
We deliver full-cycle, high-impact tech designed to scale — from seamless integrations and expert consulting to long-term operational support. Our platform powers millions of active players and drives real business growth. Call it what it is: the iGaming Platform for Champions.
With 1000+ GR8 people across locations and time zones, we don’t just ship technology — we help operators build success stories across brands, markets, and geos.
Our ambition drives us. Our people make it real.
If you’re a challenger in spirit and a champion in action — join us.
This role exists to protect platform reliability and partner trust by rapidly diagnosing and resolving complex, non-standard B2B platform incidents. You’ll help us maintain low MTTR (Mean Time to Resolution) and keep engineering focused on strategic roadmap items by owning unscripted, multi-system investigations, uncovering root causes, and serving as a strict quality filter between partner support and L3 engineering.
Incident Investigation & Root-Cause Analysis
Own end-to-end investigation for non-routine B2B operational tickets involving transactional mismatches, integration drops, and configuration failures.
Trace distributed microservice calls across Kibana and OpenSearch using correlation identifiers (Trace-ID, Request-ID, Session-ID) to isolate failures within asynchronous event streams.
Inspect Grafana metrics, error spikes, and service latencies to rapidly differentiate platform-wide degradation from localized operator misconfigurations.
Unblock operator operations autonomously by identifying configuration fixes or workaround pathways without requiring day-to-day engineering intervention.
API Diagnostics & Data Verification
Validate API endpoint behavior, payload structures, authentication tokens, and webhook/postback mechanics using Postman and cURL.
Query relational and distributed analytical databases (MySQL, PostgreSQL, Athena) to inspect real-time player states, balance ledgers, and event audit histories.
Reconcile state discrepancies across internal services and third-party payment, game, or sports feed providers.
Engineering Alignment & Quality Escalations
Filter escalated issues thoroughly to ensure only verified, reproducible platform bugs reach L3 and Development teams.
Ship reproduction-ready bug tickets in Jira complete with isolated payload examples, stack traces, database snapshots, and measurable blast-radius assessments.
Partner with QA and L3 engineers during critical defect triage to validate patches and verify staging/production fixes.
Operational Knowledge & Team Scaling
Build structured diagnostic runbooks, troubleshooting workflows, and decision trees for newly identified incident patterns.
Mentor L1 support specialists and Junior L2 colleagues through shadow sessions, log analysis training, and query optimization guidance.
Optimize support operational efficiency by identifying recurring incidents and advocating for systemic product fixes or automated alerts.
Must-Have
3+ years in L2 technical support, systems analysis, or application operations within the iGaming sector, supporting high-load transactional architectures
Advanced log analysis and distributed tracing skills in Kibana or OpenSearch, including querying stack traces and tracking requests across distributed microservices.
Hands-on API debugging proficiency with Postman or cURL, deep understanding of HTTP status codes, JSON payload schema validation, and webhook/callback mechanics.
Solid read-only SQL querying capability (PostgreSQL, MySQL, Athena) to navigate relational schemas, extract audit logs, and reconcile transactional states.
Proven observability experience with monitoring stacks (e.g., Grafana) to interpret error rate anomalies, throughput shifts, and latency degradations.
Proficiency in Jira & Jira Service Management (JSM) within multi-tier support pipelines (L1 → L2 → L3) and established SDLC workflows.
B2 English proficiency or higher, with clear written technical communication that translates complex logs into structured bug reports.
Nice-to-Have
Working knowledge of event-driven message brokers (Kafka, RabbitMQ) and distributed architecture design patterns.
Basic scripting literacy (Bash, Python) for log parsing or automating routine diagnostic tasks.
Fluency in Ukrainian or Russian.
