About us

Syndicode is an engineering partner for product delivery, data infrastructure, and AI systems — secure and compliant by design. Founded in 2014 and headquartered in Lisbon, we specialize in two verticals: construction and e-commerce.

We take accountability for the business outcome, not just the deliverables — which is why our engineers stay: our average client engagement is six years, and the same people who start a project are usually still on it years later. Our anchor engagements include four years with the innovation division of a Top-20 US builder, and six years with an e-commerce marketplace from Series B through public exit.

Our engineering team spans the US, UK, and EU, with an average tenure of 4.5 years. We hold ISO 27001 certification, with GDPR-native engineering and OWASP-standard security built in from Discovery onward. Our proprietary AI-PE Framework, battle-tested internally, now handles repetitive engineering work, so our team can focus on decisions that require judgment.

About the role

For a Lead Generation Ops Specialist position, we are looking for an excellent outbound automation practitioner and proactive channel builder who thrives on delivering outcomes to stakeholders and for the business. The ideal candidate can demonstrate a proven track record of building and scaling multi-channel outbound pipelines in IT services or agency environments targeting the US, Canadian, and European markets. We expect you to own the full outbound engine—from LinkedIn and cold email to intent-based prospecting and list building—and we are committed to providing the tools you need for our joint success.

What you'll be doing

• Build and expand outbound channels in parallel — LinkedIn, cold email, social listening, website scraping, and buyer-intent signals — so Head of Sales and SDRs consistently work with responses instead of research
• Discover and pilot new lead sources and tools, bringing data-backed proposals and launching them independently rather than waiting for direction
• Build ICP-based lists by firmographics, extract contacts by target roles, and identify tech-stack and intent signals from websites, job postings, other sources
• Run enrichment, validation, and deduplication against CRM data
• Launch and iterate on outbound campaigns jointly with Head of Sales, testing messaging variants and tracking what works with hard numbers
• Automate recurring workflows using no-code tools (waterfall enrichment, AI columns, automated quality checks) and document what's built so it doesn't depend on one person
• Monitor weekly channel performance — volume, response rate, bounce rate, meetings booked, cost per lead — and react quickly to deliverability drops, account limits, or list burnout

What you'll need

• 2–3 years of experience in outbound, lead generation, or growth ops, ideally within an IT services company or agency working with US/Canada/EU markets
• Hands-on experience running full-cycle outbound campaigns, from list building to generating replies
• Solid understanding of email deliverability fundamentals: SPF, DKIM, DMARC, domain warmup, and inbox rotation
• Practical experience with LinkedIn outbound tools (e.g., Sales Navigator, Linked Helper or similar) and cold email platforms with warmup capability
• Working knowledge of Boolean search and filter-building for prospecting and list segmentation
• Comfort working with AI tools for research and enrichment, including prompt writing and output validation
• Strong ownership mentality — proactively spotting channel drop-offs and bringing hypotheses, not just status reports
• B1 English level or higher, sufficient for working with materials and adapting sequences using AI tools

Nice to have

• Experience with Clay or similar waterfall-enrichment platforms
• Familiarity with automation tools such as n8n, Make, or Zapier
• Experience with web scraping tools (Firecrawl, Netrows, or similar)

What you'll get at Syndicode

• 15 days of vacation, 11 days off for holidays, and 20 sick leave days per year
• Fully remote job
• Educational support
• Internal tech meetups
• Continuous feedback within teams and departments
• Top-notch team
• Ability to participate in decision-making and bring new ideas
• Self-management: opportunity to manage your time and plan your activities
• Dynamic, fast-growing environment: we react and adapt quickly to world and market changes.
