Full-Stack Developer (Junior/Mid-level)
**Remote** · Full-time
The Role
We are a fast-growing B2B SaaS company operating globally in email infrastructure for cold outreach. We’re seeking a developer to lead the evolution of our backend, APIs, and automations. Here, you won’t maintain just one system: you’ll work end-to-end — moving seamlessly between backend, frontend, integrations, and other project-specific demands — always attentive to opportunities for operational improvement and optimization.
We operate 100% remotely, with real autonomy, impact-driven focus, and space to grow alongside the product. You manage your own schedule, deliver responsibly, and have the freedom to propose ideas — which quickly translate into improvements.
**Responsibilities**
* Develop, maintain, and evolve production systems, ensuring stability, security, and scalability
* Work with databases and API integrations, building and optimizing automations that support operational workflows
* Refactor and improve third-party service integrations
* Support internal teams on technical matters and analyze platform usage to propose continuous improvements
* Participate in special projects — such as new automations, internal tools, and product features — always prioritizing efficiency and tangible impact
**What We’re Looking For**
* Experience developing production software
* Solid understanding of databases and APIs, with emphasis on writing clean, organized, and secure code
* Proactive mindset: meets deadlines, thinks systemically, and solves challenges without waiting for instructions
* Passion for automation and scalable systems
* Comfort working remotely — with autonomy, strong communication skills, and accountability for deliverables
**Nice-to-Haves (non-eliminatory)**
* Experience with email infrastructure or deliverability
* Background in B2B companies
* DevOps knowledge
* Familiarity with Supabase (PostgreSQL, authentication, and security) and tools such as Airtable, Stripe, Render, Vercel, or similar
We don’t expect you to know every technology in our stack — we value curiosity, rapid learning ability, and ownership of outcomes far more.
**How We Work**
100% remote work: you manage your own schedule, choose your workspace, and enjoy time flexibility — all centered on delivery. Lean team, direct communication, and genuine space for suggestions, ownership, and technical growth. Your work directly impacts both the product and customers — and your ideas are welcomed from day one.
**Benefits**
* Competitive market-aligned salary
* Fully remote model
* Flexible working hours
