Equity: Available

Start Date: ASAP

Company Description

We’re a fast-moving SaaS startup with a validated MVP already live and early users onboard. Our platform solves a real pain point in the sales process for all companies with inbound pipeline, and we’re now gearing up for our next phase: product refinement, scalability, and growth.

We're looking for a hands-on Chief Technology Officer (CTO) to take the lead on all things technical — from owning the architecture to growing the tech team, fixing bugs, and shipping new features fast.

- Own the technical vision, architecture, and delivery of the product

- Lead and expand our product development roadmap post-MVP

- Maintain, debug, and improve our existing front-end and back-end code

- Build and lead a small, high-performance engineering team as we scale

- Collaborate closely with the founders and product team on new features

- Make smart, scalable tech stack decisions to support long-term growth

- Oversee security, infrastructure, and DevOps best practices

- Work in short sprints with a bias toward shipping and iteration

Our Current Stack

Languages & Services:

- Golang – Core services like the HubSpot listener are written in Go for performance

- Python – Some services originally built in Python, now being migrated

- Microservices-based — modular services for leads, mail, agent, onboarding, etc.

- Kafka – Message queue for inter-service communication (will migrate to AWS SQS)

- Redis – Caching and duplicate event prevention

- Docker – All services containerized

- OpenAI API – Used extensively for NLP tasks like email generation, analysis, and embedding

Frontend (planned):

- Will be handled via a Backend-for-Frontend (BFF) service once UI/UX is finalized

Databases:

- PostgreSQL (multi-tenant schema for company-specific data)

- Future RDS setup planned (production/testing environments)

3rd-Party Integrations:

- HubSpot API – For lead management, email syncing, inbox handling

- Gmail – For email capture and sending

- OpenAI – For generating emails and analyzing content

- (Planned): SMS service for additional communication channels

- Deployment in progress for staging and production

- Centralized logging planned using either:

- ELK Stack

- AWS CloudWatch

(You don’t need to have used our exact stack — just be able to work quickly in new environments.)

What We’re Looking For

- Strong experience in full-stack development (bonus if you’ve shipped SaaS products before)

- Previous leadership or team management experience — or ready to grow into it

- Ability to prioritize bug fixing, user feedback, and new feature builds simultaneously

- Comfortable with rapid iteration, MVP mindset, and scaling tech from 1 to 100

- Strong product thinking — you understand not just how to build, but what and why

- Excellent communication skills and entrepreneurial mindset

- Ideally based in UK/EU timezone, but open to remote globally

What We Offer

- Equity options — you’ll own part of what you build

- Autonomy and the opportunity to shape the technical direction

- Chance to grow into a long-term leadership role in a high-growth company

- A product-first team with deep domain knowledge and paying users

Ready to Build With Us?

- We’re not just looking for a developer. We’re looking for a partner — someone excited to shape the technical future of our product and company.
