Requirements
• Languages: Python (primary), Go, SQL Messaging & streaming: Apache Kafka Storage & databases: Databricks, BigQuery, Apache Iceberg, GCS, Mongo, Redis Data processing & orchestration: Apache Spark, DataFlow, Airflow / Cloud Composer Infrastructure: GCP, Kubernetes, Terraform AI / Agentic: LLM APIs, MCP, agent orchestration frameworks Observability: Grafana, Prometheus, Victoria Metrics, PagerDuty, Sentry, OpenTelemetry CI/CD & tooling: GitLab, Jira, Confluence AI coding agents: Cursor, Claude Code • Languages: • Messaging & streaming: • Storage & databases: • Data processing & orchestration: • Infrastructure: • AI / Agentic: • Observability: • CI/CD & tooling: • AI coding agents: • Impact • You can articulate how your contributions transformed the way engineers work and fostered a strong SRE/DevOps culture. • You can demonstrate how impactful reliability work connects to business success and customer outcomes. • Ownership • You embrace the you build it, you run it principle — you love owning what you ship. • You are cost-aware: effective vertical and horizontal autoscaling and detailed telemetry insights are how you demonstrate mindfulness of cloud spend. • Systematic approach • Systematic approach • Infrastructure as Code is the only thing that brings stability into chaos • You design for failure: SLOs, error budgets, and runbooks are first-class artifacts, not afterthoughts. • Data-driven • You use telemetry and metrics to give engineers actionable feedback on how applications and services behave. • You can navigate complex data platform architectures using distributed tracing and debugging. • Solid hands-on experience with GCP (BigQuery, DataProc, Cloud Composer, GCS) and Kubernetes. • Kubernetes • Experience with Python; Go is a strong advantage. • Python • Familiarity with data pipeline technologies (Kafka, Airflow/Cloud Composer, Spark, Iceberg) — you don't need to write ETL code, but you need to operate it reliably and know when something is wrong. • data pipeline technologies • Fluent use of AI coding agents (Cursor, Claude Code, Copilot, Gemini CLI, or similar) — you already use these tools daily to accelerate work. • Fluent use of AI coding agents • Comfortable with on-call rotation and 24/7 incident response. • on-call rotation • Remote-first mindset — you know how to be effective in distributed teams. • You are able to learn and adapt — essential when exploring new tech or navigating our growing codebase. • Strongly preferred • Experience operating single-DWH environments (Snowflak, Databricks or BigQuery). • single-DWH environments • Familiarity with agentic/LLM workloads — API reliability, latency SLOs, trace observability for AI systems. • agentic/LLM workloads • Experience with open table formats (Iceberg, Delta Lake) in production environments. • open table formats • Exposure to data security and compliance in the context of customer-facing DWH integrations (consent, data retention, PII handling). • data security and compliance • Personal qualities • Ownership & accountability — you take issues from detection through to resolution and follow-up prevention. • Ownership & accountability • Systematic thinking — you identify root causes, not symptoms, and document your findings so the team learns. • Systematic thinking • Collaboration & communication — you explain trade-offs and constraints clearly to both engineers and non-engineers. • Collaboration & communication • Bias for reliability — operational excellence (SLOs, oncall friendliness, proactive alerting) is not a chore, it's your craft. • Bias for reliability • Continuous improvement mindset — you are comfortable iterating, revisiting assumptions, and improving incrementally. • Continuous improvement mindset • Comfortable operating remote-first in a distributed team across Central Europe. • Comfortable operating remote-first • Your success story
Responsibilities
• a. Platform reliability & observability • Build and maintain the reliability ecosystem where engineers can safely develop, debug, and operate DataCraft services running on GCP and Kubernetes (DataProc, Cloud Composer, BigQuery, Snowflake/Databricks connectors). • Ensure end-to-end observability across the full data platform — from Kafka ingest through GCS/Iceberg staging, Airflow orchestration, to Databricks and BigQuery destinations — enabling the team to catch missing loads, SLA breaches, and data drifts before customers notice, or costs drift. • end-to-end observability • Drive scalability so services can scale vertically and horizontally based on operational and telemetric data (OpenTelemetry, Prometheus, Victoria Metrics). • Maintain team health dashboards and alerting (Grafana, PagerDuty, Sentry). • b. Infrastructure as Code & deployments • Own and evolve Terraform-based infrastructure for DataCraft services. • Terraform-based infrastructure • Automate deployments, instance setup, and operational runbooks to eliminate manual/semi-manual steps. • Maintain CI/CD pipelines (GitLab) with linters, security scans, and code quality checks, AI code reviews, enabling engineers to produce high-quality MRs. • CI/CD pipelines • c. Security & compliance • Help the team fulfill security requirements for ISO and SOC2 audits by enforcing security principles: key distribution, key rotation, authorization & authentication at the service level, data encryption in transit, data isolation, resource limitations, and audit logs. • ISO and SOC2 audits • Ensure data access controls are properly enforced across multi-DWH environments (BigQuery, Snowflake, Databricks). • d. Incident management & L3 support • Participate in and drive L3 on-call rotation and incident resolution for DataCraft services. • L3 on-call rotation • Contribute tooling for debugging, troubleshooting, and performance testing of data pipelines and orchestration layers. • Use telemetry data and distributed tracing to navigate complex, distributed service architectures. • e. Agentic platform reliability • Ensure reliability and observability of the Loomi Analytics Agent data infrastructure — LLM API gateway performance, MCP server health, and evaluation pipeline availability. • Loomi Analytics Agent data infrastructure • Monitor and alert on data quality issues that could introduce inconsistencies or hallucinations in Loomi's responses — making the agent's data access patterns reliable and debuggable. • Get to know the DataCraft team, the company, and the most important processes. • Set up your local and GCP development environment and complete the Engagement engineering onboarding. • Understand the current state of DataCraft services: pipelines, orchestration, observability gaps, and on-call runbooks. • Start contributing to the L3 on-call rotation, handling incidents, troubleshooting, and debugging — which will sharpen your understanding of the platform and surface fresh improvement ideas. • Deliver your first meaningful reliability improvement: an observability enhancement, a deployment automation, or an SLO definition for a key DataCraft service. • Own the reliability posture of at least one DataCraft domain end-to-end — able to independently design, operate, and continuously improve it. • Drive measurable improvements in MTTR, alert signal-to-noise ratio, or deployment confidence across the team. • Be a trusted reliability partner in architecture discussions — your input shapes how new DataCraft services are designed for operability from day one. • The pay range actually offered will take into account a variety of potential factors considered in compensation, including but not limited to skills, qualifications, geographic location, accomplishments, experience, credentials, internal equity and business needs, and may vary from the range listed above.
