ClickHouse is the open-source, real-time analytical database behind a lot of today's AI. More than 4,000 companies build on ClickHouse, including Anthropic, OpenAI, Tesla and Meta.

As a Consulting Engineer, you're the hands-on engineer on our customers' most important projects. When a customer needs to migrate, integrate, or prove ClickHouse on a real workload, you work in the build alongside their engineers: you design it, build it, test it and hand it over.

You'll work on a broad mix of projects for customers across EMEA, from moving large workloads off other databases to building new real-time analytics on ClickHouse. Each one is scoped with clear goals from the start, so you know what success looks like and can get stuck in. It's a fast way to build deep experience across lots of different data problems.

The consulting function at ClickHouse is less than a year old, so you'll help shape how ClickHouse delivers this work as the team grows. Between projects you take cases alongside support engineers, which keeps you close to day-to-day support.

WHAT YOU'LL DO

- Turn customer goals into a scoped project with measurable success criteria, sizing and a timeline

- Design a target architecture and prove it against the customer's own data: schema and engine design, capacity and sizing, proofs of concept

- Do the build: implementation, pipelines and integrations, migration execution, tooling and automation

- Measure it before it matters, with benchmarking, load and functional testing, then support the cutover

- Tune what production reveals, then hand over with an engagement report and knowledge transfer,



so the customer's team can run it without you

- Take L1 to L3 cases alongside support engineers when you're between projects

- Feed what you see in the field back to Product and Engineering, and turn your work into reference architectures, knowledge base articles and blog posts

- Work in a constant feedback loop with the Pre-sales team to ensure that the demos and POCs they present are credible when you put them into production

WHAT YOU'LL BRING

- 5+ years delivering hands-on technical work for customers, whether your title was consultant, professional services, solutions architect, senior support, SRE or something else

- Real depth in databases, whether analytical, transactional or relational

- Hands-on SQL. You regularly write complex queries from scratch, and tune and debug them yourself

- You've owned implementations, migrations or POCs for external customers from start to finish

- Hands-on cloud experience (AWS, GCP and/or Azure)

- You've deployed and run workloads on Kubernetes yourself

- You give precise technical answers and explain them clearly

- Fluent English

NICE TO HAVE

- Experience with ClickHouse

- Hands-on Splunk experience





- Migrating analytical workloads from systems such as PostgreSQL, Snowflake, BigQuery or Elastic

- Terraform

- Data pipelines and streaming, such as Kafka, Kinesis, Spark or Debezium

- Python, Bash or Go

- Involvement in open source, as a user, contributor or community member

GOOD TO KNOW

- This role is remote within EMEA, in a country where ClickHouse already hires

- Travel to customer sites is part of the job, up to 35% of your time, depending on the project: some need none, others weekly visits

- You'll join our EMEA Support Services team, where Support Engineers, Consulting Engineers and TAM Architects work as one team

- You'll be part of the on-call rotation, about one week a quarter, with time off in lieu if you're paged at a weekend

HOW WE HIRE

- A 30-minute call with our recruiter

- A conversation with the hiring manager

- A take-home exercise, designed to take three to four hours, with three working days to complete it

- A 90-minute technical interview with the team: you'll walk us through your take-home, then join a working session where you write and tune SQL live

- A final conversation with our VP of Support Services

- References, then an offer

The working session is without AI tools, so make sure you're comfortable writing queries from scratch. Download open-source ClickHouse and practise: it's free, easy to install, and great preparation.
