About SalesMonk.ai

SalesMonk.ai is on a mission to revolutionize sales and marketing with cutting-edge AI agents that empower teams to close deals faster and smarter. We are a fast-growing startup, backed by a passionate team of innovators, problem-solvers, and builders.

We are looking for a Senior Full Stack Engineer to join our core engineering team and play a pivotal role in building scalable, high-performing applications for our next-gen platform.

Why join

As a small team, we work in a highly collaborative environment and you'll have the opportunity to participate in every part of the business from idea to production.

• Impact: Build the foundation and shape engineering practices, team, and company culture.
• Excellence: Practice your craft with other ICs and founders in a well-organized, fast-paced environment.
• Ownership: Influence the direction of product and strategy — we care about your opinions.
• Leadership: Mentor the next generation of the team that comes in raw and hungry.
• We’re AI geeks: We use AI not just for our product, but also to code, do reviews, control our browsers, play Spotify…and we’re just getting started 🤓

What you'll do (responsibilities)

We're looking for an experienced individual contributor who enjoys working alongside other experienced engineers and designers to quickly build and iterate on the frontend and backend.

• Build AI agents that change the game. You'll build the infrastructure for SalesMonk from the ground up, having a huge and direct impact by shipping your work to users on prod daily.
• Use modern web tech and influence the stack. The frontend is React/Next.js, the backend Node(and a bit of Python) , and we use TypeScript across the full stack. As we build out our stack, you get to make critical choices and lay the foundations.
• Self-direct your work and co-own the product. You're a technical founder type and will have autonomy and responsibility. You'll be involved in shaping the roadmap and will own the problems, not just the code.
• Create a robust and scalable backend. Build multi-agent AI systems, PostgreSQL database models, performant REST API with Rediscache, 3rd party integrations, product analytics, transactional email, and service monitoring. We currently deploy to Render and Vercel to keep DevOps simple and will be looking for you to establish viable long-term cloud infrastructure and operations.
• Build UI components. You'll implement UI based on our design system. For a lot of our product, we build UI directly using codegen. Design sense is a must!
• Solve interesting technical problems. Bring your full creativity to solve super-challenging technical problems: from complex backend architecture, non-deterministic LLM behaviours, 3rd party integrations, syncing app state, to real-time collaboration.

What we're looking for (qualifications)

You're a senior IC that has built such systems before and this is not an area you have to ramp up on. We don't require any formal qualifications but value learning new skills — especially from one another. We are looking for someone that feels a sense of duty to the users of their work.

• Startup experience. Working in a startup requires a level of hustle that isn’t for everyone. If you’ve been through this before (ideally running your own startup) then you’re going thrive in our energy. ****
• Highly productive while producing quality code. You enjoy pushing out features in a pragmatic and maintainable way. You know when to use duct tape and when to lay a foundation.
• AI wizard. We’re leaning hard into optimising our engineering processes with code. You should have a strong understanding of coding best practices, and be keeping up to date with the latest in the field.
• Curious and quick learning. We don't expect you to have experience in every technology we use, but to learn and be productive quickly. Owning several repos and jumping into all of them doesn't scare you.
• Design sensibility. While you'll co-craft the interface with top designers and frontend engineers, we expect you to have a knack for great UX, such that you feel if something is off and can flag it, or better yet, polish it.
• Attention to detail while pragmatic. We strive for few slips in code, Git hygiene, and clear written communication — all while remaining low-ego and simply focusing on solutions.
• Good heart. We don't tolerate jerks and are generally just friendly people!

What we offer (compensation & benefits)

We'll treat you well. If there are any other benefits that are important to you, we'd like to hear.

• Competitive salary and equity — multiple options based on your desire for ownership.
• Remote-friendly culture — while the role is primarily in office, you can work remotely if a need arises.
• Premium co-working space — work from a WeWork in the heart of Gurgaon.
• Hardware setup — MacBook Pro if you need it, big display, and accessories.

Skills and Experience :

• 2-7 years of experience as a Java/J2EE developer.
