Backend Engineer

We are looking for a strong Backend Engineer with 3-5 years of hands-on experience building scalable, reliable backend systems for consumer or B2B product companies. This is an opportunity for someone who enjoys working in an early-stage startup environment, takes end-to-end ownership, and wants to build products rather than work on assigned tickets. You will work closely with the founding/product/engineering team to design, build, and scale backend services powering Biopeak's technology platform.
Responsibilities:
Design, develop, and maintain scalable backend services and APIs.
Build robust RESTful APIs and backend systems for product features.
Work closely with product, frontend, data, and business teams to translate requirements into reliable solutions.
Design efficient database schemas, queries, and data models.
Build integrations with internal and third-party systems/APIs.
Focus on performance, scalability, security, and reliability.
Write clean, maintainable, and production-ready code.
Participate in architecture and technical design discussions.
Debug production issues and proactively improve system reliability.
Contribute to engineering practices, code reviews, testing, and CI/CD.
Take ownership of features from problem understanding, design development, deployment, and monitoring.
Requirements:
Currently working with or has previously worked at a product company, consumer-tech company, SaaS company, or early-stage startup.
Has built products/features that are live in production.
Comfortable working with ambiguity and changing requirements.
Strong ownership mindset: someone who can independently take a feature from idea to production.
Enjoys working in small, high-performing engineering teams.
Strong coding fundamentals and engineering judgment.
Someone who wants to build 01 and 110 products, rather than work in a large process-heavy environment.
Must-Have Skills:
3-5 years of strong backend engineering experience.
Strong proficiency in Python / Node.js / Java / Go or another modern backend language.
Strong understanding of REST APIs, backend architecture, and distributed systems fundamentals.
Hands-on experience with SQL databases such as PostgreSQL/MySQL.
Experience with NoSQL databases such as MongoDB/Redis is a plus.
Good understanding of cloud infrastructure, preferably AWS/GCP.
Experience with Git, CI/CD, and production deployments.
Strong problem-solving and debugging skills.
Experience building and scaling production-grade applications.
Preferred Background:
Candidates from product-led companies, SaaS startups, consumer-tech companies, fintech, health-tech, AI/ML, or other technology startups are preferred.
Not preferred: Candidates whose experience is predominantly from traditional IT services/outsourcing companies without significant product-building exposure.
