Description

About Supernormal

Work shapes who we are. It’s how we grow, contribute, and make an impact. But for many, work still feels like a grind. Even in the digital age, productivity tools often add more friction than flow. At Supernormal, we are working to make work better. We build AI-powered tools that streamline workflows, boost collaboration, accelerate impact, and make the super, normal.

The Role

We’re looking for a talented and motivated Backend Software Engineer who can pair deep technical expertise with leadership that elevates the entire team. You’ve guided complex projects from idea to impact, and you know how to set direction without losing sight of the details. You’ll be at the center of Supernormal’s technical future, shaping our AI backend while mentoring others to do the best work of their careers.

This is a high-ownership, high-impact role. You won’t be a cog in a large machine — you’ll be a key contributor who shapes the architecture and quality of our backend from the ground up. You’ll report to the Head of Engineering and work closely with the full engineering team, product, and design.

What you’ll work on

• Design, build, and maintain scalable, reliable backend services and APIs that power Supernormal’s core product.
• Own backend features end-to-end — from technical design through implementation, testing, and production monitoring.
• Collaborate with frontend engineers and product to define and implement clean, well-documented API contracts.
• Identify and address performance bottlenecks, reliability issues, and scalability concerns proactively.
• Participate in code reviews, contribute to engineering standards, and help maintain a high-quality, well-tested codebase.
• Contribute to infrastructure decisions: cloud architecture, deployment pipelines, observability, and on-call practices.

Requirements

What We’re Looking For

• 6+ years of professional backend software engineering experience, with a strong grasp of distributed systems and API design.
• Proficiency with large Rust, Typescript, and Ruby codebases
• Experience building and operating production systems at scale — you understand what it means to ship and own something in the real world.
• Solid understanding of cloud infrastructure (AWS, GCP, or Azure), containerization, and CI/CD pipelines.
• Comfort working in a fast-moving, small-team environment where priorities can shift and ownership is broad.
• Strong communication skills — you can explain technical trade-offs clearly and collaborate well across the team.
• A bias toward action and simplicity: you default to shipping and iterating rather than over-engineering.

Nice to Have

• Experience with real-time data processing, streaming architectures (e.g., Kafka, Pub/Sub), or WebSockets.
• Familiarity with speech-to-text APIs (e.g., Deepgram, AssemblyAI, Whisper) or LLM integration (OpenAI, Anthropic, etc.).
• Background in productivity, collaboration, or enterprise SaaS products.
• Experience with data pipelines, async job processing, or event-driven architectures.
