Lead Generation Specialist

Olive Systems is looking for an experienced Lead Generation Specialist to build a consistent pipeline of qualified B2B opportunities across Israel, the US, and Europe.

This is a hands-on role. You will research companies, identify potential needs, find decision-makers, discover relevant projects, run outbound campaigns, submit proposals, and continuously test new ways to generate conversations with potential clients.

Who We Are

Olive Systems is a technology services company working with startups, technology companies, and established businesses.

We help our clients solve engineering and product challenges across four core areas:

IT Outstaffing

We help companies extend their engineering teams with dedicated remote developers and technical specialists. We source engineers specifically for each client’s requirements, while the client works with them directly as part of their team.

AI Implementation

We design and implement practical AI solutions for existing products and business processes, including AI agents, RAG systems, LLM integrations, voice and chat AI, workflow automation, and custom AI-powered features.

Web Scraping & Data Collection

We build and maintain scalable scraping and data collection infrastructure, from individual custom scrapers to large-scale systems collecting and processing data from thousands of websites.

Custom Software Development

We build SaaS products, web applications, backend systems, APIs, integrations, internal platforms, automation solutions, and other custom software.

Your job is to understand these services well enough to recognize where there is a potential business opportunity and how to approach it.

What You’ll Do

You will own day-to-day outbound lead generation across several channels:

* LinkedIn: identify target companies and relevant decision-makers, research potential triggers and needs, build prospect lists, run personalized outreach, and follow up.

* Cold Email: research prospects, build targeted campaigns, personalize messaging, manage sequences, and optimize campaigns based on results.

* Upwork: continuously monitor relevant projects, qualify opportunities, prepare tailored proposals, submit applications, and manage initial conversations.

* XPlace: find relevant opportunities on the Israeli market, evaluate projects, submit proposals, and handle initial communication.

* Research companies before outreach to understand their product, team, technology, hiring activity, and potential needs.

* Identify founders, CTOs, VP Engineering, Heads of Engineering, Product leaders, and other relevant decision-makers.

* Find new channels, signals, and approaches for generating opportunities.

* Maintain an organized pipeline and accurately track outreach activity and results.

* Analyze what generates replies, meetings, and qualified opportunities, and continuously improve the process.

* Work directly with Olive Systems’ management on ICPs, messaging, offers, and new outbound experiments.

What We’re Looking For

* 2+ years of experience in B2B lead generation, outbound sales, SDR, or business development.

* Experience generating leads for software development, IT services, outsourcing/outstaffing, AI, SaaS, or other B2B technology services.

* Strong hands-on experience with LinkedIn and Sales Navigator.

* Practical experience with cold email outreach.

* Experience working with Upwork and submitting proposals for software/IT projects.

* Strong prospect and company research skills.

* Ability to understand a company’s business and identify potential needs instead of blindly following a lead list.

* Ability to write concise, personalized outreach that sounds human.

* Good understanding of software development and the technology industry.

* Strong written English.

* Comfortable working with CRM and lead-generation tools.

* Independent and proactive approach to work.

Strong Advantage

Experience with the Israeli market and XPlace, Hebrew, or previous lead generation for software development agencies/outstaffing companies will be a significant advantage.

Experience with tools such as Apollo, Clay, Instantly, Lemlist, Sales Navigator, or similar platforms is also valuable.

What Success Looks Like

We don’t measure success by sending thousands of generic messages.

We care about qualified opportunities and conversations with companies that could realistically become Olive Systems clients.

A strong person in this role should be able to look at a company or project and answer:

Why could they need us? Who should we contact? What should we offer them? And what is the best way to start the conversation?

If you are used to simply receiving a database and sending templates, this role probably isn’t the right fit.

If you enjoy researching companies, finding opportunities others miss, experimenting with outbound approaches, and turning cold prospects into real sales conversations, we’d like to talk.

• Experience building LLM applications, agent/tool workflows, RAG systems, or model-provider integrations
• Strong production instincts: diagnosing failures via logs, metrics, and traces; designing for fault tolerance, retries, cancellation, and recovery
• SQL and familiarity with data platform concepts: catalogs, metadata, schemas, governance, lineage
• Comfort leading ambiguous, cross-service work with clear stakeholder communication and strong written documentation
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

DESIRED SKILLS

• LangChain4j or similar agent frameworks
• Python for AI services, evaluation harnesses, or sandboxed execution
• React and TypeScript
• gRPC, protobuf, Quarkus, Kubernetes, MongoDB, KV stores, event-driven architectures
• Apache Arrow, Apache Iceberg, OpenLineage, semantic layers, or data-governance systems
• AI quality evaluation: LLM-as-judge, model benchmarking, production AI metrics

About Deep Knowledge Group

Deep Knowledge Group (https://www.dkv.global/) builds large-scale analytical databases, investment-intelligence systems, industry ecosystem platforms, competitiveness indices and interactive dashboards across frontier industries including AI, Longevity, HealthTech, DeepTech and QuantumTech.

The Data Science department builds and maintains the industry intelligence databases behind those products — organisations, people, products and the relationships between them, across multiple sectors and regions. Every one of them starts as messy public data and has to end up as a clean, deduplicated, verifiable dataset that analysts and downstream products can rely on.
 

About the Role

We currently build each database the way the last one was built. Collectors are source-specific scripts, scheduling is manual, quality is whatever the person who built it checked, and nothing links one database to another. That works at our current size and will not work at the next one.

We are looking for a Senior Data Engineer to own the shared platform that replaces this: one collection and enrichment framework that every database runs on, with orchestration, monitoring, provenance and entity resolution as properties of the system rather than as things individual engineers remember to do.

This is an ownership role. You will work directly with the Head of Data Science on architecture, and you will be the person other engineers bring design decisions to. We are not looking for an extra pair of hands; we are looking for a second point of technical decision-making in the department.
 

Key Responsibilities

• Design and own the shared collection and enrichment framework: what is reusable, what stays source-specific, and where the line between them sits.
• Own orchestration end to end — scheduling, dependencies, retries, backfills, incremental and idempotent re-runs.
• Make entity resolution a permanent service rather than a per-project effort: blocking, matching, thresholds, and a defensible account of why a merge was made.
• Design the provenance model: every value traceable to its source, its retrieval date and the logic that transformed it, six months after the fact.
• Establish the staging-and-promotion rule and enforce it: nothing writes to production tables directly.
• Build monitoring and observability for data, not only for jobs — freshness, coverage, null rates, distribution drift, source schema changes.
• Define the quality standard: accuracy, completeness, duplicate rate, freshness, provenance — and the instrument that measures it.
• Set the schemas, conventions and review standards that the rest of the department works to.
• Design the deterministic backbone of our agent network, and decide where an agent is warranted and where plain code is cheaper, faster and testable.
• Migrate existing databases onto the shared framework alongside the engineers who built them.
• Mentor and unblock other engineers; take architectural decisions off the Head of Department's desk.
   

Required Skills

• Strong Python — you write services and pipelines, not notebooks.
• You have owned a data platform, not just tasks on one — orchestration, scheduling, monitoring, backfills.
• Airflow, Dagster or Prefect in production, with a considered view on why that one.
• SQL and PostgreSQL in depth — indexing, query plans, schema design, migrations.
• Entity resolution or record linkage across sources that disagree with each other, including how you measured whether it worked.
• You have set the standards other people then worked to: schemas, conventions, review.
• Docker, CI/CD, and comfort running production systems on plain infrastructure rather than a managed platform.
• Practical experience with LLM APIs and with validating non-deterministic output before it reaches a production table.
• Data quality discipline: you can state a dataset's duplicate rate or field staleness with evidence, not by inspection.
• The ability to write a design down clearly enough that someone can argue with it.
   

Strong Advantages

• Production collection from public web sources: anti-bot, JS-rendered pages, undocumented APIs, source drift.
• Knowledge graphs, ontologies and canonical entity models across multiple domains.
• Data lineage and governance tooling in production, used by people other than its author.
• Agent orchestration frameworks, and a clear view of their limits.
• Vector search and RAG pipelines.
• Experience turning a team's ad-hoc scripts into a framework that team then adopted.
• OSINT methodology and source verification.
   

What We Will Evaluate

Two things, mostly.

You question your own data. The engineers who work out well here are the ones who notice that a source silently changed its schema, that a 97% match rate is hiding a systematic bias, that a field is populated but wrong. Volume without verification is worth nothing to us.

You explain your reasoning. Much of this work involves judgment calls that nobody can check quickly — which record wins a merge, what confidence threshold to use, when to stop enriching. We need those decisions written down and defensible, not buried in a script.

The hiring process is an intro call, a short practical task on real data, a technical review of your solution, and an offer. We evaluate the task on judgment, not polish: reproducibility, honest handling of edge cases, and clear reasoning about what you chose not to do count for more than a clever one-liner.
