Join us to reimagine how businesses integrate data and automate processes – with AI at the core.

About FloData

FloData is re-imagining the iPaaS and Business Process Automation (BPA) space for a new era - one where business teams, not just IT, can integrate data, run automations, and solve ops bottlenecks using intuitive, AI-driven interfaces. We're a small, hands-on team with a deep technical foundation and strong industry connects. Backed by real-world learnings from our earlier platform version, we're now going all-in on building a generative AI-first experience.

The Opportunity

We're looking for a Full-Stack Tech Lead who can drive the development of our new platform while mentoring a small but capable team. You'll own technical delivery across the stack (Next.js, Nest.js, Spring Boot, LangGraph on AWS), influence architecture decisions, and work closely with leadership on bringing our product vision to life.

If you're excited about building AI-native experiences, love working across the stack, and thrive in a fast-paced startup environment, this is your chance to shape a category-defining product.

What You'll Do

• Spend 70% of your time designing, building, and reviewing software across frontend, backend, and AI layers
• Guide a small engineering team (30% of your time) and lead from the front
• Translate product and business needs into system designs and execution plans
• Own the delivery of features and infrastructure that can scale to enterprise-grade workloads
• Unblock the team, champion engineering best practices, and build a culture of quality
• Contribute to architectural decisions and introduce new technologies as needed (e. g., queuing, observability, etc. )
• Be a mentor, collaborator, and the go-to person for complex technical decisions
• Advocate and implement AI-first principles in every layer of the product

You Might Be a Fit If You Have

• 6-8 years of experience building and scaling full-stack applications
• Proven track record in early-stage B2B SaaS or platform engineering teams
• Strong command over modern web stacks - ideally Next.js, Nest.js, and Spring Boot
• Comfort working with AWS and hybrid/on-premise infra setups
• Experience or deep interest in building AI-powered user experiences (LangGraph, LLMs, etc.)
• A strong sense of ownership, product thinking, and attention to detail
• Startup mindset: resourceful, fast-moving, and outcome-focused
• Experience with enterprise IT SAAS software (Salesforce, Oracle ERP, Netsuite, etc) is a plus

Why Join Us

• Build a generational product at the intersection of AI, automation, and data
• Work closely with founders and leadership with no layers of bureaucracy
• Have end-to-end ownership of what you ship
• Help shape the culture and tech foundations of a new, ambitious company
• Onsite in Hyderabad, with flexibility when needed

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.
