About JobStream
JobStream is rethinking how employers unlock value from their candidate databases. Instead of letting millions of past applicants sit idle, we help organizations re-engage talent, deliver better candidate experiences, and generate measurable hiring outcomes through intelligent matching and automated campaigns.
We’re an early-stage company with ambitious goals, tackling real problems in the talent acquisition space. Backed by a leading private equity firm, we’re now looking for our first senior full stack engineer to join the team and help us turn big ideas into scalable, secure technology. If you’re entrepreneurial at heart and thrive in fast-moving, high-ownership environments, this is your chance to help shape both the product and engineering culture from the ground up.
What You’ll Do
- End-to-End Development: Design and build features across the stack — from backend APIs and data pipelines to frontend interfaces in React.
- Database Engineering: Work with PostgreSQL and other relational databases, designing efficient schemas and queries for large-scale candidate data ingestion and matching.
- Data Integration & Flows: Implement secure and scalable ingestion workflows, leveraging tools like Supabase and BPM automation frameworks (e.g., n8n, Airflow).
- Security & Compliance: Lead efforts around data privacy, security, and compliance — including policies, anonymization, and safe handling of candidate data.
- Matchmaking & Personalization: Experiment with rules-based matching and lightweight AI/LLM components to improve job-to-candidate recommendations.
- Email Campaign Systems: Build and optimize infrastructure for automated rejection emails, job recommendations, and candidate engagement campaigns.
- Frontend Development: Contribute to user-facing dashboards and campaign tools with React and modern JavaScript/TypeScript.
- Scalable Architecture: Help design a secure, cloud-native architecture that can grow as pilots turn into scaled deployments.
- Collaboration & Leadership: Work closely with the founding team to translate business needs into technical requirements; mentor future hires as we grow the engineering team.
- Experimentation: Contribute to rapid pilots and controlled tests, measuring conversion rates, match quality, and unit economics.
Minimum Qualifications
- 5+ years of professional software engineering experience, with a strong full stack background.
- Hands-on expertise with PostgreSQL (or similar RDBMS), schema design, and optimization.
- Strong frontend development skills with React and modern component-driven frameworks.
- Proven backend engineering skills with Node.js, Python, or similar.
- Experience with Supabase or similar platforms for authentication, database, and APIs.
- Familiarity with workflow/BPM tools like n8n, Airflow, or comparable frameworks.
- Strong understanding of security, data privacy, and compliance considerations in handling sensitive data.
- Comfortable operating in a startup-style environment where you own projects end-to-end.
- Excellent problem-solving skills and ability to collaborate closely with non-technical stakeholders.
Nice to Have
- Experience building matchmaking or recommendation systems (rules-based or AI-driven).
- Background in email campaign platforms, deliverability, or affiliate marketing systems.
- Knowledge of scaling architectures for high-volume transactional systems.
- Exposure to HR tech, talent acquisition systems (ATS/CRM), or job boards.
- Experience with cloud-native platforms (AWS, GCP, Azure).
Why Join Us?
At JobStream, you’ll be joining at a pivotal moment: we’re small, scrappy, and focused — which means your work will directly shape the product, the architecture, and the company’s future. As the first senior engineer, you’ll have the autonomy to make big technical decisions, influence the roadmap, and set engineering best practices from day one.
You’ll also get the excitement of startup-building with the stability of PE backing — the best of both worlds.
Benefits & Perks
- Competitive salary with meaningful equity potential
- Health, dental, vision, and life insurance
- Generous PTO and flexible remote work
- The opportunity to be a foundational team member shaping the future of the company
If you’re excited about building from the ground up, solving hard problems at the intersection of data, security, and recruiting, and want to own your impact — we’d love to hear from you.
