• AI & Smart Tooling — Use AI to accelerate the workflow, evaluate new tools, and raise AI fluency across the team.

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

What should you know about SKELAR? It's a venture builder — in other words, a company that builds companies. Together with founders, we create consumer businesses that become leaders in global markets across EdTech, Mental Health, Petcare, FashionTech, and beyond.

Our teams build tech products that win recognition from Product Hunt and The Webby Awards, earn thousands of glowing Trustpilot reviews, and reach over 10 million users worldwide. That kind of impact doesn't happen by accident — it starts with exceptional people, and our people are our top priority.

We've built an environment where expertise meets opportunity, and where there's no ceiling on what you can achieve. Now we're looking for the kind of people who don't just want a job — they want a challenge.

We’re looking for a Middle Node.js Developer for our partner company, Duomo.

Duomo is an app rooted in Christian values, helping people turn Scripture into daily habits and inner peace. We’re building a leading Christian-tech product for people seeking spiritual renewal.

You will be responsible for:
 

• Driving MarTech Automation: Designing, developing, and scaling backend services to automate marketing technology processes and integration workflows.
• Streamlining Creative Processes: Building robust tools and systems that automate the asset lifecycle and streamline creative operations for the team.
• Enhancing System Observability: Implementing comprehensive tracking, metrics, logs, and tracing (Observability) to ensure high system visibility and performance monitoring.
• Strengthening Infrastructure Reliability: Expanding test coverage (unit, integration, end-to-end) and setting up automated testing pipelines to ensure high code quality and fault tolerance.
• Architecting Scalable Solutions: Participating in system architecture design, code reviews, and optimizing backend performance to support business growth.

What you need to succeed in this role:

• 2+ years of experience with Node.js + TypeScript & NestJS.
• PostgreSQL + any typed ORM (Drizzle, Prisma, or TypeORM).
• Redis & Message Queues (BullMQ, RabbitMQ, or SQS) — hands-on experience with idempotency, retries, and distributed locks.
• Third-party REST API integrations — handling rate limits, pagination, and partial failures.

• Docker, CI/CD, and unit testing with Jest

   

  Nice-to-Have Requirements

• Experience with Facebook Marketing API, Google Ads API, or other ad platforms (TikTok, Applovin)
• Cloud & Infra: AWS (ECS, ECR, S3, Lambda) and GitHub Actions
• Observability: Prometheus, Grafana, and structured logging
• Integrations with Airtable API and Google Sheets API
• Practical experience with LLM APIs (Claude, Gemini) — structured output and prompt versioning

Why Duomo:

— You’ll work on a product with a clear mission and real values.
— You’ll help us transition from a content-rich app into a truly connected spiritual platform.
— You’ll be early enough to influence how product is done at Duomo long-term.

What we offer:

— Competitive salary;
— Significant impact on a rapidly growing business and contribution to how it shapes up;
— Ample career opportunities for ambitious growth and development;
— A possibility to attend internal, external courses, seminars and the access to a corporate library;
— Comfortable working environment. We provide all necessary work equipment for your role and serve complimentary breakfasts, lunches, and snacks in the office;
— 20 days of paid vacation, medical insurance and a variety of sports activities available for employees inside and outside the office.

At SKELAR, we've built an environment where people can grow, build, and do the most meaningful work of their careers:

• SKELAR Platform. The operational backbone of our venture builder. It exists to help founders move faster and easier — so business teams can stay laser-focused on the product while 10+ specialized Platform takes care of everything else: Legal, Finance, HR, Admin, Talent Acquisition, Employer Branding, IT, and more.
• Networking and knowledge-sharing as a way of life. Our people include co-founders who've launched multiple businesses and some of the sharpest specialists in the industry. Whatever expertise you need, it's never far away.
• Learning programs you won't find anywhere else. We've developed our own educational tracks for teammates to choose from — a two-month school for first-time managers, intensive AI workshops, and professional clubs for engineers, product managers, and more.
• Meaningful impact in Ukraine. The SKELAR Foundation was created by our own people, and every employee plays a part in bringing important social initiatives to life. We founded Europe's first accelerator for veterans and are working to build lasting support structures for veterans at a national scale.
• Spaces designed to inspire. Our offices are places people actually want to be — with an in-house gym, a climbing wall, Bali-inspired green spaces, and libraries. Every detail, from service and security to comfort and design, is built to match the pace of our growing teams.
• Everyday comfort built in. Meals, gym access in Kyiv or a partial fitness stipend in Warsaw, health insurance, paid business travel where the role requires it, and corporate partner discounts.

We'd love to tell you more in person.
