— ability to work effectively in a distributed, highly communicative team.

Nice-to-have requirements:
— commercial experience with Oracle Database and Oracle-specific SQL behaviour;

We’re looking for a proactive Talent Acquisition Partner to join our team and grow alongside our business.

This is not a traditional recruiter role.

Recruiting will be your primary responsibility, but you’ll also communicate directly with clients, help improve our AI hiring platform, contribute ideas, and gradually become involved in different parts of the business as you gain experience.

About us

We build two businesses that work closely together to transform how companies hire technical talent.

Our first business is an AI-powered hiring platform that helps companies evaluate candidates more efficiently. We combine AI-driven resume analysis, voice interviews, and candidate evaluation with human expertise to help companies hire faster without sacrificing quality.

Our second business partners with startups and technology companies to help them build exceptional engineering teams. We specialize in finding and placing highly skilled software engineers, DevOps engineers, AI specialists, QA engineers, and other technical professionals for companies primarily across Israel, North America, and Europe.

Although these are two separate businesses, they complement each other and share the same mission: helping technology companies build stronger teams through better hiring.

As part of our team, you’ll work across both businesses, with a particular focus on growing and improving our AI hiring platform.

Your responsibilities

Talent Acquisition (~70%)

* Work directly with clients to understand hiring needs.

* Gather detailed information about open positions.

* Write compelling, high-quality job descriptions.

* Publish vacancies across multiple platforms.

* Source candidates using LinkedIn, job boards, referrals, AI tools, and other channels.

* Screen candidates and conduct initial interviews.

* Coordinate interviews between candidates and clients.

* Maintain hiring pipelines and ensure every process keeps moving.

* Deliver an excellent experience for both candidates and clients.

Client Communication (~10%)

* Communicate directly with clients throughout the hiring process.

* Present candidate profiles.

* Collect and follow up on feedback.

* Schedule interviews.

* Keep clients updated.

* Make sure nothing gets stuck because someone forgot to follow up.

Product & Operations (~20%)

You’ll actively participate in improving our AI hiring platform.

We’re looking for someone who constantly thinks about questions like:

* How can we make candidate interviews better?

* What repetitive work should be automated?

* How can recruiters work more efficiently?

* What features would improve the customer experience?

* How can our internal processes become better?

You won’t be expected to make product or business decisions on your own, but we expect you to bring ideas, challenge assumptions, and actively participate in discussions.

Over time, you’ll also become involved in customer meetings, product discussions, and other strategic initiatives.

One more thing. We value people who pay attention to details and genuinely care about what they’re applying for. If that’s you, please start your cover letter with BANANAS so we know you actually read the description.

What we’re looking for

Experience matters, but mindset matters much more.

We’re happy to teach the right person.

Requirements

* At least 6 months of experience in recruiting, talent acquisition, HR, customer success, or another people-facing role.

* Strong spoken and written English (strong B2 minimum, ideally C1).

* Excellent communication skills.

* Strong organizational skills.

* Ability to manage multiple hiring processes simultaneously.

* Comfortable working in a startup environment where priorities evolve.

* Curious, proactive, and eager to learn.

* Basic understanding of technology (you don’t need to be an engineer, but you should know the difference between Java and JavaScript and feel comfortable discussing technical roles).

AI is a requirement

We expect everyone on our team to actively use AI every day.

At a minimum, you should already be comfortable working with:

* ChatGPT

* Claude

* Codex

We believe AI makes great people significantly more productive. If you rarely use AI or aren’t interested in integrating it into your daily work, this role probably isn’t the right fit.

The most important quality: Proactivity

This is more important than experience.

We don’t micromanage.

We don’t assign every task.

We expect you to think, notice, communicate, and take initiative.

That means:

* reminding clients before we’re asked;

* following up with candidates without waiting for instructions;

* asking questions when you’re blocked instead of waiting;

* noticing opportunities to improve our product or processes;

* bringing ideas instead of simply executing tasks.

We’d much rather hear:

“I noticed this could work better. Here’s what I suggest.”

than:

“Nobody asked me to do it.”

If you’re unsure what to do next, we don’t expect you to sit and wait. We expect you to ask, challenge, suggest, and keep things moving. We’d much rather answer a question than discover days later that nothing happened because no one asked.

This role isn’t for you if…

* You prefer waiting for instructions.

* You need constant supervision.

* You dislike communicating with people.

* You don’t actively use AI.

* You’re uncomfortable with change or ambiguity.

* You want a predictable corporate environment with clearly defined responsibilities and little change.

* You’re only looking for a traditional recruiting role.

Growth

We’re looking for someone who wants to become a long-term partner in building the business.

As you grow, you’ll have opportunities to become more involved in client relationships, product development, business operations, and strategic initiatives.

We’re not hiring someone to fill a seat.

We’re looking for someone who wants to help build something meaningful with us.

Summary

We're preparing to roll out a brand-new marketplace section on our platform. Before we remove the staging gates, open up indexing, and kick off a massive programmatic expansion, we need a sharp, hands-on Technical SEO specialist to audit our foundation and stress-test our scaling strategy.

This initial project covers a full technical audit and expansion roadmap for Phase 1 (approx. 50+ pages). If we hit it off, there's an immediate second phase with an identical scope for another high-priority section of our site.

What You'll Be Doing

You'll dive into a gated staging environment (we'll provide crawler access credentials) currently set to noindex, nofollow and deliver a prioritized breakdown (P0/P1/P2) across five key areas:

1. Technical Foundation & Indexability

• Audit schema markup accuracy across dynamic page templates (ItemList, Organization, local business schemas, etc.)
• Validate canonical structures, dynamic sitemaps, and base-path routing logic (/staging/ vs. final production URL architecture)
• Plan for redirects, crawl efficiency, and Core Web Vitals readiness

2. Keyword Strategy & Information Architecture

• Ensure page templates match target search intent without thin content or cannibalisation risks
• Run a competitive gap analysis against top players in our space

3. Internal Linking & Site Structure

• Evaluate hub-and-spoke structures, orphan risk, and anchor text distribution
• Map out how this new section should interlink with our primary root domain

4. Programmatic Expansion & Scaling Strategy (Crucial)

• Critique our plan to scale into hundreds of dynamic programmatic URLs (geo-hubs, category pages, guides)
• Evaluate our Supply Gate Rule (indexing pages only once they hit a specific threshold of live listings) to prevent thin or doorway page penalties
• Advise on URL architecture, link equity distribution, and crawl budget management at scale

5. Pre-Launch Flip Plan

• Outline a strict checklist of non-negotiable fixes required before we turn on search engine indexing

Deliverables

• Prioritised Findings Document — Actionable feedback broken down by severity (P0, P1, P2) with concrete dev instructions
• Expansion Build Roadmap — Recommended rollout sequence for page types and geographic/category expansions
• Pre-Launch Checklist — The sign-off sheet before we flip the switch

Who You Are

• A seasoned SEO engineer or technical SEO consultant with proven experience in programmatic SEO (pSEO) and directory or marketplace platforms
• Fluent in schema, JS rendering, crawl logs, and index management
• Pragmatic and direct — you deliver clear, actionable fixes prioritized by real business impact, not just raw automated site audits
• Excellent written communication skills

How to Apply

Drop us a brief note outlining:

1. A quick summary of your technical SEO experience with pSEO or supply-gated directory platforms
2. Your standard approach to auditing gated staging environments
3. Your availability to start right away
4. Price quote for a 200-page section

Thanks, 
Ron

• Initiative — proposes improvements instead of waiting for instructions

We offer

• Competitive salary
• Reservation from mobilization
• On-site work with access to hardware and lab facilities

About B2Spin

We are B2Spin, and we are dedicated to delivering the best Free-to-Play Social Casino and gaming experiences by creating captivating, engaging, and unique products that are accessible to everyone. We have built a team of talented professionals from all over the globe, who are working to continually improve the experiences of our players. We are not looking to just be part of the industry, but to revolutionize it.

AI-Driven Engineering Culture

We are actively building an AI-driven engineering organization with a clear and deliberate stance: artificial intelligence is a core part of how we build and deliver software — not an experiment, not a trend, and not an optional add-on.

AI is embedded into our engineering workflows, from system design and prototyping to refactoring, testing, and code review. We expect engineers to be fully comfortable working in AI-driven environments and to treat AI as a primary productivity multiplier. Strong engineering judgment, architectural ownership, and accountability remain essential—AI amplifies our engineers, it doesn’t replace responsibility for technical decisions.

What you will be doing
• Design, evolve, and maintain core libraries, framework extensions, and shared components used across all engineering teams
• Take ownership of system performance, scalability, and high-load architecture, ensuring core services can handle massive throughput with low latency
• Proactively monitor production behavior, investigate complex application/database performance bottlenecks, and introduce advanced metrics, dashboards, and alerting systems
• Establish and advocate for best practices in concurrency, memory management, and resource utilization across the backend ecosystem
• Collaborate with cross-functional teams including backend, web, mobile, QA, and product teams
• Take ownership of specific functional areas within our large-scale architecture
• Leverage AI tools and assistants as integral parts of your development workflow—from system design to code review
• Contribute to maintaining high test coverage, predictable production behavior, and seamless scalability
• Drive engineering excellence through modern practices and continuous improvement

What we are looking for
• Deep, low-level understanding of Java internals (JVM, GC behavior, memory management, concurrency/multithreading, and performance profiling)
• Advanced knowledge of relational databases (PostgreSQL), including query optimization, indexing strategies, locking mechanisms, and connection pooling under heavy load and distributed systems architecture, specifically high-throughput event streaming with Kafka (partitioning, replication, consumer group rebalancing, and tuning).
• Strong system design, troubleshooting and debugging capabilities
• Comfortable and proactive in using AI coding assistants (GitHub Copilot, Claude Code, etc.) as productivity multipliers
• Practical experience validating, refining, and taking ownership of AI-generated output
• Upper-intermediate or higher level of English

Nice to have:
• Proven track record of building or maintaining shared libraries, SDKs, or internal tooling in a large-scale engineering organization.
• Hands-on experience with APM tools and observability stacks (Prometheus, Grafana, ELK) with the ability to define meaningful SLOs/SLIs, custom metrics, and proactive alerts.

Main technologies: Java, Spring, Spring Boot, Ebean-ORM, Quartz, Maven, Resteasy, Flyway, PostgreSQL 15, HTTP/Websockets, Netty, K8S/Docker, GCP, Jenkins, ELK, Grafana.

We're looking for a Senior Python Engineer to become the technical owner of the backend platform: you decide how it is built.

The MVP is live and it proved the product works. Now it has to become a platform that holds under load, over unreliable networks, on a 24/7 production system - which means new services designed properly, an engineering standard that does not exist yet (Spec-Driven Development, AI-powered pipelines, CI/CD, review), and the old shortcuts retired along the way.

What you'll do

• Take full ownership of the backend: Django, DRF, FastAPI services, Celery, PostgreSQL, TimescaleDB, Redis, and the OPC UA components
• Audit the existing MVP end to end and define the refactoring strategy.
• Design reliable failover for site connectivity so telemetry and commands keep working over unstable networks
• Balance fast product validation against long-term platform stability, and re-prioritize when the business shifts
• Build AI-powered engineering workflows (agentic pipelines) and make Spec-Driven Development the standard
• Work with cybersecurity specialists on IEC 62443 and translate its requirements into platform architecture
• Set the engineering standards: code quality, reviews, CI/CD, testing, API stability

Must have

• 6+ years of commercial Python, with strong production experience across: Django and DRF, FastAPI (Pydantic v2), Celery, PostgreSQL, Redis, Docker / Docker Compose, pytest and CI/CD
• System design, hands-on: you have defined service boundaries, API contracts, data flows and scalable architectures for production - and can walk through decisions you made and what they cost
• Authorization models by design: RBAC, least privilege, Django/DRF permission systems, object-level permissions, and consistent enforcement across distributed services
• Resilient third-party integrations: retries with exponential backoff, rate-limit handling, Redis caching and invalidation strategies, graceful degradation when an upstream service goes down
• OPC UA - working knowledge: client/server model, namespaces, subscriptions, security modes
• AI-driven engineering: contract-first / Spec-Driven Development (OpenAPI/Swagger, Pydantic, gRPC), plus experience building or using agentic pipelines - CrewAI, LangGraph, or your own orchestration - to automate code generation, tests, documentation, review or integration validation
• English B2+

Nice to have

• Modbus TCP/RTU or other industrial protocols
• IEC 62443 / OT security
• TimescaleDB, InfluxDB or ClickHouse; MongoDB
• Redis beyond simple caching
• Observability: Sentry, Flower, structured logging
• Refactoring legacy production systems without downtime
