HRAVITY is looking for a Technical Recruiter to join our team. We are a technical recruitment agency placing Senior+ engineers and tech leaders at product companies and startups across the US and EU. We don’t do volume hiring, we work with small and mid-sized teams who care about hiring quality over speed.
 

Our team mainly works in a full recruitment cycle: from the first call with a hiring manager to an accepted offer. The focus of this role is on driving sourcing and recruitment efforts, as part of a small agile team. You'll run 1–3 open roles at a time, just enough to actually understand what each client needs and find the right person. This role is ideal for candidates with an educational background in IT or some initial experience in the tech field, who are eager to grow their career in recruitment.
 

WHAT AM I GOING TO DO?

• Active sourcing — most of your candidates won't be actively looking. You'll build outreach strategies, test new channels, quickly read what the market looks like for a given role, and iterate until you find what works.
• Job marketing — write JDs that attract the right people, choose where to post them, and manage the inbound flow
• Screening & interviews — you'll talk to a lot of people. For each conversation, there are two jobs: present the role in a way that makes the right candidate interested, and run a structured interview to assess whether they actually fit.
• Coordination — schedule interviews, keep all sides aligned, and make sure the process moves without unnecessary delays. The best candidate experience often comes down to this.
• Client collaboration — run discovery calls, ask the questions hiring managers didn't think to answer, and turn vague requirements into a search strategy. Iterate, update, be a partner and lead client through the process.
• Talent pipeline — build and maintain a reserve of strong candidates you've already vetted. Keep relationships warm so when a role opens, you're not starting from zero.
• Process & records — keep the ATS (Notion) clean, up to date, and document what works. We're a small team, so good habits here matter.
   

WHAT ARE THE QUALIFICATIONS?

• 2+ years in IT recruitment, ideally with US or EU markets
• Strong sourcer — you know your way around sourcing tools and automation, and don't rely on one channel
• Strong English (B2) — you'll be writing JDs, running interviews, and managing client relationships in it daily
• Education in IT or completed technical courses — you understand how software is built, can read a tech stack, and follow a conversation with developers
• Structured thinker — you communicate in a clear way, prioritize well, and can articulate your reasoning
• Self-driven — you manage your own workload, flag issues before they become problems, and don't need someone to check if things are moving. We trust people to own their work without being reminded.
   

WHAT ARE THE WORKING CONDITIONS?

• Remote-first setup, flexible working hours and unlimited vacation policy
• Supportive and collaborative atmosphere with flat hierarchies and BS-free environment
• Full tax and expense coverage, all necessary equipment, tools, and resources
• Competitive base salary with uncapped performance-based bonuses
• Comprehensive insurance coverage, gym memberships and more

About the Client

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

About the Role

We are looking for a Middle-level SDET to design and maintain automated tests for a large-scale distributed data platform. You will validate the correctness, performance, and reliability of the query engine, connectivity layer, and backend services across all major clouds.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

Responsibilities

• Develop and maintain automated tests in Python / pytest for backend services, REST APIs, and distributed data components.
• Write end-to-end, integration, and regression tests covering SQL query execution, data correctness, and platform APIs.
• Support performance and load testing with JMeter, including workloads over JDBC / ODBC / Arrow Flight drivers.
• Validate data-intensive scenarios — query plans, result correctness across data sources, metadata consistency, and behavior under concurrency.
• Contribute to CI/CD test pipelines in Jenkins — configure, maintain, and troubleshoot.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker.
• Investigate failures across the stack — query engine, distributed services, drivers, infrastructure — and drive them to resolution with engineering.
• Collaborate with US-based developers on testability and quality gates.

Required Qualifications

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with a solid grasp of OOP and software design principles.
• SQL & Data: Strong SQL skills and solid understanding of how relational and analytical data systems work.
• Data-intensive testing experience: Hands-on experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 3+ years in backend/system test automation or SDET roles.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and deploying/maintaining test environments.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

Desired Skills

• Experience testing REST APIs and backend microservices at scale.
• Familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines (e.g., Presto, Trino, or similar).
• Understanding of modern data lakehouse concepts, open table formats (Apache Iceberg), and data warehousing.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Performance testing with JMeter or comparable load-testing tools.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Understanding of query plan generation, query acceleration / materializations, and metadata integrity in distributed data systems.

HRAVITY is looking for a Technical Recruiter to join our team. We are a technical recruitment agency placing Senior+ engineers and tech leaders at product companies and startups across the US and EU. We don’t do volume hiring, we work with small and mid-sized teams who care about hiring quality over speed.
 

Our team mainly works in a full recruitment cycle: from the first call with a hiring manager to an accepted offer. The focus of this role is on driving sourcing and recruitment efforts, as part of a small agile team. You'll run 1–3 open roles at a time, just enough to actually understand what each client needs and find the right person. This role is ideal for candidates with an educational background in IT or some initial experience in the tech field, who are eager to grow their career in recruitment.
 

WHAT AM I GOING TO DO?

• Active sourcing — most of your candidates won't be actively looking. You'll build outreach strategies, test new channels, quickly read what the market looks like for a given role, and iterate until you find what works.
• Job marketing — write JDs that attract the right people, choose where to post them, and manage the inbound flow
• Screening & interviews — you'll talk to a lot of people. For each conversation, there are two jobs: present the role in a way that makes the right candidate interested, and run a structured interview to assess whether they actually fit.
• Coordination — schedule interviews, keep all sides aligned, and make sure the process moves without unnecessary delays. The best candidate experience often comes down to this.
• Client collaboration — run discovery calls, ask the questions hiring managers didn't think to answer, and turn vague requirements into a search strategy. Iterate, update, be a partner and lead client through the process.
• Talent pipeline — build and maintain a reserve of strong candidates you've already vetted. Keep relationships warm so when a role opens, you're not starting from zero.
• Process & records — keep the ATS (Notion) clean, up to date, and document what works. We're a small team, so good habits here matter.
   

WHAT ARE THE QUALIFICATIONS?

• 2+ years in IT recruitment, ideally with US or EU markets
• Strong sourcer — you know your way around sourcing tools and automation, and don't rely on one channel
• Strong English (B2) — you'll be writing JDs, running interviews, and managing client relationships in it daily
• Education in IT or completed technical courses — you understand how software is built, can read a tech stack, and follow a conversation with developers
• Structured thinker — you communicate in a clear way, prioritize well, and can articulate your reasoning
• Self-driven — you manage your own workload, flag issues before they become problems, and don't need someone to check if things are moving. We trust people to own their work without being reminded.
   

WHAT ARE THE WORKING CONDITIONS?

• Remote-first setup, flexible working hours and unlimited vacation policy
• Supportive and collaborative atmosphere with flat hierarchies and BS-free environment
• Full tax and expense coverage, all necessary equipment, tools, and resources
• Competitive base salary with uncapped performance-based bonuses
• Comprehensive insurance coverage, gym memberships and more
