Ever wanted to take full ownership of a backend and have a real impact on how the product is built?
Where you're not just implementing tickets, but making architectural decisions, thinking about scalability, and building systems that can support a growing product?
Where you can work closely with the founder, influence technical direction, and eventually help lead another backend engineer?
If you enjoy building production-grade backend systems, solving architectural challenges, and taking ownership beyond your individual tasks – we'd love to talk.<\/p>\n
About the Company
Our client is a technology startup building a LinkedIn-based sales technology platform designed to help businesses improve and automate their sales processes.
The platform is built as a multi-tenant system and combines modern cloud infrastructure with AI-powered functionality, including integrations with Google's Gemini models.
It's a product-focused environment where engineering decisions have a direct impact on the platform and its ability to scale.<\/p>\n
The Role
We're looking for a Senior Backend Engineer who will take full ownership of the backend and effectively act as the technical lead for this area.
You'll be responsible for designing and building scalable backend systems, making architectural decisions, and ensuring the platform remains reliable as it grows.
You'll work closely with the founder, who has a strong technical background, so this role requires genuine engineering depth and the ability to explain and defend technical decisions.
As the team grows, you'll also help guide and collaborate with another backend developer.<\/p>\n
What You'll Do
Backend & Architecture
Design, build, and maintain backend services using Python
Develop scalable APIs and business logic for a production SaaS platform
Design and optimize PostgreSQL databases and data models
Make architectural decisions around scalability, reliability, and maintainability
Take full ownership of backend development and technical direction
Multi-Tenant & Cloud Systems
Build and maintain multi-tenant production systems
Design solutions that securely and reliably support multiple customers
Work with cloud infrastructure and production environments
Monitor, troubleshoot, and improve system performance and reliability
AI & Product Integrations
Work with AI-powered features and integrations, including Google Gemini
Integrate external APIs and third-party services into the platform
Understand how AI capabilities fit into a larger production architecture rather than treating AI-generated code as a replacement for engineering judgment
Technical Leadership
Drive backend technical decisions and development standards
Review code and provide technical guidance
Work closely with the founder on architecture and product decisions
Eventually support and guide another backend developer
Take ownership of technical problems from investigation through implementation and production
Cross-Functional Development
Work with frontend developers and contribute to product features beyond the backend when needed
Have enough frontend understanding to collaborate effectively and understand the full product flow
Work in a startup environment where priorities can move quickly and engineers are expected to take ownership<\/p>\n
What You Bring
4+ years of strong commercial backend development experience
Strong hands-on experience with Python
Solid experience with PostgreSQL
Experience building and maintaining multi-tenant production systems
Experience working with cloud-based infrastructure
Strong understanding of backend architecture, scalability, and system design
Experience working on production systems before the recent AI boom – you understand engineering fundamentals and can make technical decisions independently
Ability to understand the wider product, including some frontend concepts and user-facing flows
Experience working in a startup or fast-moving product environment is a strong plus
Strong ownership mindset and willingness to go the extra mile when the product requires it
Comfortable communicating directly with technical stakeholders and defending your engineering decisions
Upper-Intermediate English or higher<\/p>\n
Nice to Have
Experience with SaaS or sales technology platforms
Experience with AI\/LLM integrations, particularly Google Gemini
Experience designing multi-tenant architectures from the ground up
Previous experience acting as a technical lead or owning a backend domain independently
Experience mentoring or guiding other developers
Startup experience
Frontend experience with modern JavaScript\/TypeScript frameworks<\/p>\n
What You Get
Full Backend Ownership: You won't be just another backend developer – you'll own the backend architecture and technical direction.
Direct Technical Influence: Work closely with a technical founder and have a real voice in architectural and engineering decisions.
Product Ownership: See your technical decisions directly influence a growing product and its users.
Modern Technology: Work with Python, PostgreSQL, cloud infrastructure, multi-tenant architecture, and AI-powered functionality.
Technical Growth: As the team grows, you'll have the opportunity to take on more technical leadership and guide other engineers.
Startup Environment: Fast-moving, direct, and focused on building rather than unnecessary processes and hierarchy.<\/p>\n
