Promin Apps is a product-first company on a mission to help people feel better, move more, and live healthier lives — physically and emotionally. At the intersection of AI, data, behavioral science, and personalization, we build thoughtful digital products that support meaningful lifestyle change.
Now, we’re looking for a Senior Backend Engineer — someone who will take ownership of our serverless backend architecture and help us build a reliable, scalable foundation for a fast-growing product.
Why this role is worth your attention: — Work with a modern codebase built with up-to-date technologies — no legacy constraints. — Take part in high-level system design and architectural decisions. — Contribute to a product that uses AI to meaningfully personalize user experience, turning data into real, tangible value for users. — Operate in a flat structure with fast decision-making and minimal bureaucracy. — Build a product that delivers real value and has a measurable impact on users’ lives. — A professional growth path within backend and infrastructure engineering, with increasing ownership over system design, reliability, and platform-level decisions as the product scales.
What you will do: — Build and maintain serverless backend services on AWS (Lambda, SQS, RDS). — Own serverless.yml configuration: deployments, stages, environments, IAM policies. — Design and evolve asynchronous message-driven workflows (retries, DLQs, monitoring, failure recovery). — Optimize PostgreSQL (Amazon RDS) performance and reliability (indexes, migrations, scaling strategies). — Implement monitoring and alerting, improve production stability and observability. — Collaborate closely with frontend and product teams. — Contribute to architecture and technical decision-making.
What we’re looking for: — 5+ years of professional software development experience. — Strong backend expertise with Python (3+ years). — Hands-on experience with AWS Lambda (function design, packaging, deployment, monitoring, cold starts). — Skills with Serverless Framework and serverless.yml (stages, variables, IAM roles, plugins, CI/CD). — Production experience with Amazon RDS (PostgreSQL). — Confident use of Amazon SQS: standard vs FIFO queues, retries, DLQs, idempotency, visibility timeouts and backpressure patterns. — Strong understanding of REST API design. — Observability experience: CloudWatch logs & metrics, alarms, structured logging, basic tracing. — Deep understanding of security fundamentals: IAM least-privilege approach, secrets management (SSM / Secrets Manager), encryption basics, VPC fundamentals. — Product mindset and autonomy in decision-making. — English level: B1 and higher.
Will be a plus: — Experience integrating payment providers. — Experience with Google Spreadsheets integrations.
What we offer: — Fully remote setup with flexible working hours. — Benefits package (paid vacation, sick leave, and more). — Support for personal and professional growth. — Access to a curated corporate knowledge library.
We believe work should have meaning. At Promin, you’ll build systems that matter — with people who respect your experience and engineering ideas.
