Hello,
We are on the lookout for a full stack developer well versed with MongoDb, React.js (& Next), Node.js and AWS.
A bit about the company - We are building India’s first payment gateway focused on offline (cash on delivery) payments. Over 70% of India chooses to pay through cash on delivery whilst shopping online. We are tapping that market. CODfirm currently is used by 500+ brands to verify COD orders and reduce returns and fraud on their stores.
A bit about our team - We are a small team. Three part-time full-stack developers and one full-time product/ business guy. We are currently looking for our first full-time developer.
Our culture - We are a bunch of individuals who absolutely love what we do. Always jolly and super self-motivated. We hate chasing each other for work and deadlines. It goes without saying that it is mandatory for everyone to meet their deadlines and to be punctual. There is no hierarchy whatsoever and everyone is open and receptive to feedback and constructive criticism. What keeps us motivated and driven is our vision for CODfirm. It does get stressful at times, just like it would at any fast-growing startup with a grand vision. In a sentence, it is a fun yet challenging work environment.
About the role and responsibilities - For us, technical and cultural fit is equally important. Since we already covered the cultural bit, let’s now talk to the developer side of you.
Must-haves:
- Advanced knowledge and hands-on experience of MongoDB, Redis, React.js (and Next), Node.js and AWS.
- Ability to write scalable, understandable and testable code.
- Strong understanding of computer science principles: data structures, algorithms, distributed systems and information revival
- Strong communication skills to help shape the product roadmap given your knowledge and experience with the codebase
- Ability to turn designs shared into frontend code with a focus on UX
- Open to learning new technologies and programming languages
Good to have:
- Knowledge of GraphQL
- Data analytics and machine training skills
The interview process:
Step 1: You apply for the job and share your past work with us
Step 2: You get on an intro call with the founder
Step 3: You solve an assignment
Step 4: We get on a call again to discuss the assignment and to get to know you better Step 6: We offer you to come on board and join us
Step 7: Together we build CODfirm India’s first offline payments gateway.

Job Title: Full stack Developer
Location: Coimbatore
Job Type: Full Time
Experience Level: 5-8 Years
Why This Role Matters
We’re looking for a Principal Engineer to lead the architecture and execution of our GenAI-powered, self-serve marketing platforms. You will work directly with the CEO to shape, build, and scale products that change how marketers interact with data and AI. This is intrapreneurship in action — not a sandbox innovation lab, but a real-world product with traction, velocity, and high stakes.
What You'll Do
- Co-own product architecture and direction alongside the CEO.
- Build GenAI-native, full-stack platforms from MVP to scale — powered by LLMs, agents, and predictive AI.
- Own the full stack: React (frontend), Node.js/Python (backend), GCP (infra), BigQuery (data), and vector databases (AI).
- Lead a lean, high-caliber team with a hands-on, unblock-and-coach mindset.
- Drive rapid iteration with rigor, balancing short-term delivery with long-term resilience.
- Ensure scalability, observability, and fault tolerance in multi-tenant, cloud-native environments.
- Bridge business and tech — aligning execution with evolving user and market insights.
What You Bring
- 8–12 years of experience building and scaling full-stack, data-heavy or AI-driven products.
- Fluency in React, Node.js, and Google Cloud (Functions, BigQuery, Cloud SQL, Airflow, etc.).
- Hands-on experience with GenAI tools (LangChain, OpenAI APIs, LlamaIndex) is a bonus.
- Track record of shipping products from ambiguity to impact.
- Strong product mindset — your goal is user value, not just elegant code.
- Architectural leadership with ownership of engineering rigor and scaling best practices.
- Startup or founder DNA — you’ve built things from scratch and know how to move fast without breaking things.
Who You Are
- A former founder, senior IC, or tech lead who’s done zero-to-one and 1-to-n scaling.
- Hungry for ownership and velocity — frustrated by bureaucracy or stagnation.
- You code because you care about solving real problems for real users.
- You’re pragmatic, hands-on, and grounded in first principles.
- You understand that great software isn't just shipped — it's hardened, maintained, and evolves with minimal manual effort.
- You’re open to evolving into a founding engineer role with influence over the tech vision and culture.
What You Get
- Equity in a high-growth product-led startup.
- A chance to build global products out of India with full-stack and GenAI innovation.
- Access to high-context decision-making and direct collaboration with the CEO.
- A tight, ego-free team and a culture that values clarity, ownership, learning, and candor.
Why YOptima?
