Senior Backend Engineer at Peec AI

What you’ll do

• Take ownership of complex backend systems end-to-end - from scoping and architecture to high-quality, reliable delivery

• Design and build robust, scalable APIs and distributed systems that power our products and deliver exceptional performance

• Collaborate closely with Product, Frontend, and Design teams to translate product ideas into well-architected backend solutions

• Push the boundaries of what’s possible with modern backend technologies, driving innovation in both architecture and developer experience

• Contribute to evolving our backend architecture, infrastructure, and developer tooling to support rapid iteration at scale

• Proactively identify opportunities to improve system performance, reliability, and developer experience - and drive those initiatives through to execution

What we’re looking for

• 5+ years of professional backend engineering experience, ideally in fast-paced startup or high-growth environments

• Deep expertise in TypeScript and modern backend frameworks, with a proven track record of building and scaling production systems

• Experience designing and implementing APIs (REST, GraphQL, or gRPC) that power user-facing products

• Strong experience working with SQL databases (e.g. PostgreSQL), including schema design, query optimization, and data modeling for production systems

• Familiarity with cloud-native architectures, ideally on GCP (e.g. Cloud Functions, Cloud Tasks, Firestore)

• Familiarity with DevOps practices, CI/CD pipelines, and infrastructure-as-code

• Strong communication skills and a high sense of ownership - able to operate with autonomy while staying aligned with team goals

• Some markers of excellence, which could also be non-work related, like having a high FIDE rating

• Most importantly: we care deeply about working with genuinely kind, collaborative, and hard-working people who make the team better through empathy and openness

• Backend: GCP, Cloud Functions, Cloud Tasks, RabbitMC, Firestore, PostgreSQL, Elasticsearch

• Background working on AI products or data-heavy applications
