Become a Senior SRE for Bloomreach!

Join the newly form Datacraft team — the team building the next-generation data platform for Bloomreach Engagement. Datacraft owns three interconnected domains:

• Data Warehouses (~60%) — making Bloomreach data first-class in customer DWHs (Snowflake, BigQuery, Databricks). The strategic goal for 2026–27 is to use DWHs to exponentially accelerate data adoption.
• Loomi Analytics Agent (~20%) — evolving Loomi Analytics into an agentic analytics assistant that can explore data across systems, explain insights, and act on them.
• Dashboards & Analytics Stack (~20%) — moving Engagement reporting onto DWH-backed, modern analytics stacks (semantic layers, headless BI tools).

As a Senior SRE, you will be the reliability backbone of this AI-first data team. Your work will directly impact the deployments, pipelines, reliability, and observability of pipelines and services that hundreds of enterprise customers depend on — from data exports into Databricks and BigQuery, to the  AI agent Loomi uses to surface insights.

Datacraft is an AI-first team. We believe code is a commodity and expect every engineer to fluently use coding agents (e.g., Cursor, Claude Code, Copilot, Gemini CLI) as a core part of their daily workflow. The ability to leverage AI tooling to accelerate development, prototyping, and problem-solving is not optional — it's foundational. 

For candidates at the P3 / Senior SRE level, starting monthly compensation begins at 3 800 € gross, with the final offer tailored for each candidate based on their skills and experience. Stock options and a comprehensive benefits package are also included. Working in one of our Central European offices (Bratislava, Praha, Brno) or from home on a full-time basis, you'll become a core part of the Engineering team.

What challenge awaits you?

As a P3 (Senior) SRE at Bloomreach, you are an independent professional — expert in reliability engineering, able to decompose objectives into actionable infrastructure improvements, and lead initiatives end-to-end with minimal day-to-day guidance.

We need you to build and operate an ecosystem where data engineers can safely and efficiently develop, debug, and operate data-intensive jobs and services — spanning Kafka ingest pipelines, Iceberg data lakes, multi-DWH exports, Databricks deployment and orchestration (Airflow / Cloud Composer), and agentic AI workloads.

Your 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.
• 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.
• 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.

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.
• 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.
• 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.
• 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.

Our tech stack

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

Your qualifications

Professional experience

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

• 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.

Technical skills

• Solid hands-on experience with GCP (BigQuery, DataProc, Cloud Composer, GCS) and Kubernetes.
• Experience with Python; Go is a strong advantage.
• 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.
• Fluent use of AI coding agents (Cursor, Claude Code, Copilot, Gemini CLI, or similar) — you already use these tools daily to accelerate work.
• Comfortable with on-call rotation and 24/7 incident response.
• 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).
• Familiarity with agentic/LLM workloads — API reliability, latency SLOs, trace observability for AI systems.
• Experience with open table formats (Iceberg, Delta Lake) in production environments.
• Exposure to data security and compliance in the context of customer-facing DWH integrations (consent, data retention, PII handling).

Personal qualities

• Ownership & accountability — you take issues from detection through to resolution and follow-up prevention.
• Systematic thinking — you identify root causes, not symptoms, and document your findings so the team learns.
• Collaboration & communication — you explain trade-offs and constraints clearly to both engineers and non-engineers.
• Bias for reliability — operational excellence (SLOs, oncall friendliness, proactive alerting) is not a chore, it's your craft.
• Continuous improvement mindset — you are comfortable iterating, revisiting assumptions, and improving incrementally.
• Comfortable operating remote-first in a distributed team across Central Europe.

Your success story

In 30 days:

• 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.

In 90 days:

• 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.

In 180 days:

• 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.

Help us evolve and scale the Bloomreach Engagement UI design system and become our new UI Developer. Implement new designs, and create and maintain UI components used across our product. You’ll sit at the intersection of design, engineering, and product, turning ideas into intuitive, robust, and beautiful interfaces. For candidates at the P3 / Senior level, starting monthly compensation begins at 3 500 € gross, with the final offer tailored for each candidate based on their skills and experience. Stock options and a comprehensive benefits package are also included. Working in one of our Central European offices (Bratislava, Brno, Prague) or from home on a full-time basis, you’ll become a core part of our Frontend Team. 

What tech stack do we use?

• Our styles are written in Sass (SCSS).
• Our Engagement app currently runs on Angular.
• We use JavaScript/TypeScript for application logic.
• We use Git for version control.
• Our build process uses Nx + Angular CLI, with custom ts-node and Node scripts.

You don’t need to be an expert in every framework from day one, but you should be comfortable working in at least one modern SPA framework (Angular, React, or Vue) and curious to learn the others.

What challenge awaits you?

As a Bloomreach UI Developer, you will be the go‑to person for:

• Designing and implementing UI components and patterns that are reused across the Engagement app.
• Evolving our in‑house UI framework and design system so that it’s easier and faster for product and engineering teams to build consistent experiences.
• Collaborating tightly with product designers to bring new ideas to life and to keep our visual language coherent.
• Bringing a CSS architecture mindset to a large codebase so styles remain modular, predictable, and easy to refactor over time.
• Leveraging AI in your daily work — from code generation and refactoring suggestions to documentation and quick UI experiments.

Our goal is to make our Engagement app easy to use and visually pleasant for our customers. You’ll operate on three levels: bug fixing, maintenance and creation of UI components, and implementation of new designs — with a strong focus on the design‑system layer and product outcomes. Having a great developer experience is also something we’re serious about.

Your job will be to:

1. Expand & maintain our UI design system and components library
2. Improve & maintain our in‑house SCSS framework
3. Implement new designs and product experiences

a. Expand & maintain our UI design system and components library

• Understand how our components work under the hood and enable frontend developers to build advanced interfaces using our framework.
• Design and implement reusable UI primitives (tokens, layout primitives, form controls) and higher‑level components in a way that can be applied across Angular applications.
• Revise code of the components frequently and keep up with the latest possibilities of CSS (e.g. container queries, cascade layers, new color functions) and how they affect our architecture.
• Ensure cross‑browser compatibility (modern browsers only) and good accessibility practices.
• Shape visual representation and behavior together with designers, acting as a technical partner in design reviews.
• Maintain and improve our internal “Showcase”/component gallery as a single source of truth for our design system (documentation, usage examples).

b. Improve & maintain our in‑house SCSS framework

• Extend and update core functions, mixins, and utilities that help us write styles efficiently and keep them easy to reason about.
• Evolve our CSS architecture (e.g. layers, naming conventions, design tokens, theming approach) to keep the system scalable as the product grows.
• Identify and remove legacy styles, dead code, and inconsistencies, focusing on performance and maintainability.
• Use AI‑powered tooling where it makes sense (code search, refactor suggestions, documentation summaries) to speed up this work.

c. Implement new designs and product experiences

• Update existing screens to match the latest design specs and interaction patterns.
• Research the best strategies for comprehensive changes — understanding how components are reused across screens and in different contexts — and propose pragmatic rollout plans.
• Work closely with product managers and designers to make trade‑offs that balance UX quality, technical feasibility, and delivery timelines.
• Ensure that visual and structural changes don’t introduce any bugs — partnering with QA and using tools (including AI‑assisted testing where appropriate) to catch regressions early.

Your success story will be:

• In 30 days, you will learn how our methodology works, ship your first UI bug fixes, and start contributing to small improvements in our design system.
• In 90 days, you will understand how our core components and SCSS framework work, co‑own at least one part of the design system, and support other frontend developers on a sprint project — including reviewing their usage of UI components and any styling or template changes.
• In 180 days, you will be able to tackle most tasks on your own, question and challenge designs with confidence, propose and drive improvements to our UI architecture, and help shape the future roadmap of our design system.

You have the following experience and qualities:

1. Professional — CSS, Sass, working with browser,  programming skills, Git, knowledge of Angular (optionally React or Vue), familiarity with web components is an advantage.
2. Personal — team player, honesty, responsibility, motivation

Professional experience

• Strong CSS and Sass skills — CSS will be your bread and butter and for a smooth experience it’s good if you know: selector types and specificity, fonts, relative units, box sizing, positioning, flexbox, grid, responsiveness, pseudo elements, animations, and their performance impacts.
• Experience with writing maintainable, modular, component‑based CSS
• Experience building or significantly contributing to a design system or UI component library (tokens, components, documentation, versioning, rollout).
• Comfortable with intermediate programming in JavaScript or TypeScript — structuring code, working with asynchronous logic, and debugging — and using that knowledge to implement or adjust UI behavior in Angular/React/Vue components.
• Hands‑on experience with at least one modern frontend framework (Angular, React, or Vue). Curiosity to apply design‑system thinking across frameworks is a plus.
• Familiarity with Git and standard workflows (branching, pull/merge requests, code review).
• A genuine passion for modern CSS and web UI, keeping an eye on new specs and browser capabilities and knowing when (and when not) to use them.
• An architecture mindset when it comes to stylesheets: you think in layers, dependencies, and long‑term maintainability, not just “what works right now”.
• Openness to leveraging AI in the development process — for example, using AI tools to explore refactoring options, generate variants, or support documentation — while still owning the final quality of the solution.

Personal qualities

• Product‑oriented mindset: you care about the problem we’re solving and the impact on the user, not only the implementation details.
• Ability to work in a team where we value diversity and open‑mindedness.
• Willingness to discuss problems honestly, keep focus on what’s important, and look for outcomes, not blame.
• Sense of ownership and responsibility — you follow through on what you start and care about the quality of your work in production.
• Motivation to grow: you enjoy your craft, seek feedback, and look for ways to improve both the product and the system you’re building on.
