Senior Developer – AI Sales Automation & Data Intelligence (Remote)

About Brightvision

Brightvision is a Swedish B2B marketing and technology agency working with some of the most exciting SaaS and tech companies in Europe and the US. We combine strategy, creativity, and technology to build scalable solutions that drive business growth.

Our software development team in the Philippines currently consists of 5 highly skilled full-stack developers, and we’re now looking for two additional developers with specialized expertise to help us build our next-generation SaaS platform.

What are we building?

We’re building Coseller – our proprietary B2B sales technology platform that combines AI-driven outreach automation with deep company and contact intelligence. Think of it as the intersection of tools like 11x (AI SDR) and FullEnrich/Apollo (data enrichment) – but purpose-built for the European B2B tech market.

We’re hiring for two distinct roles on this platform. You’ll apply for the one that best matches your background:

Profile A: AI SDR Module Developer

You’ll be building our AI-powered Sales Development Representative (SDR) module – a system that automates and semi-automates outbound email and LinkedIn communication based on GTM (Go-To-Market) workflows and best practices.

What you’ll work on:

• Building AI-driven email sequencing and LinkedIn outreach flows

• Designing and implementing multi-channel GTM automation pipelines

• Integrating LLMs (Claude/OpenAI) for personalized message generation, tone matching, and response handling

• Building smart scheduling, A/B testing, and performance analytics for outreach campaigns

• Creating configurable automation rules (fully automatic vs. human-in-the-loop modes)

What we’re looking for:

• Proven experience building AI-driven email and/or LinkedIn outreach software

• Familiarity with email deliverability best practices (SPF, DKIM, DMARC, warm-up, sending limits)

• Experience with LinkedIn automation (API, browser automation, or similar)

• Understanding of B2B sales/GTM workflows and how outbound sequences work in practice

• Experience integrating LLM APIs for content generation in production systems

• Strong backend skills (Node.js, TypeScript, REST/GraphQL APIs)

Profile B: Data Intelligence & Enrichment Developer

You’ll be building our data intelligence engine – transforming our existing Nordic B2B database (Bigbase) into a full-featured data enrichment and search platform, comparable to FullEnrich, Lusha, or Apollo, but with a Nordic edge.

What you’ll work on:

• Building advanced search and filtering tools for company and contact data

• Designing data cleaning, deduplication, and quality scoring pipelines

• Creating integrations with external data providers and APIs for enrichment and verification

• Building export and campaign-creation flows from search results

• Developing database management tools for large-scale B2B contact datasets

• Structuring the platform for both internal use and future external commercialization

What we’re looking for:

• Proven experience building data enrichment, search, or contact intelligence platforms

• Strong database skills – experience with large-scale data management, cleaning, and deduplication

• Experience building integrations against third-party data sources and APIs

• Familiarity with search technologies (Elasticsearch, PostgreSQL full-text search, or similar)

• Understanding of B2B data structures (company hierarchies, job titles, contact matching)

• Backend proficiency (Node.js, TypeScript, MongoDB/PostgreSQL)

For both roles, you should also have:

• 5+ years of experience as a developer

• Experience with our core tech stack: React, Next.js, TypeScript, Node.js, MongoDB/PostgreSQL

• Experience with AI-assisted development tools (Claude Code, Cursor, or similar) at an advanced level

• Familiarity with AWS services (Lambda, S3, CloudFront)

• Excellent English communication skills

• Reliable, proactive, and comfortable working independently in a remote-first team

What we offer

• Long-term, full-time freelance contract

• Work with a friendly, talented, international team

• Opportunity to shape products from the ground up – not maintaining legacy code

• Flexible schedule and fully remote setup

• A company that values growth, trust, and collaboration

At Brightvision, we believe in collaboration, trust, and continuous learning. You’ll never feel like “just another freelancer” – you’ll be part of a team that supports each other’s success. When working with Brightvision, you embrace the values outlined in our Culture Handbook. These values will guide you in making the right choices.

Please apply with your CV, GitHub/portfolio link, and a brief introduction describing which profile (A or B) you’re applying for and your relevant experience.

We hope to hear from you!
