Mern Stack Developer

Looking for somone with strong in AI, who have built the application and scaled them . Start up work exposure

8+ years of experience in successfully building, deploying, and running complex, large-scale web or data products.

Proven Management Experience: Demonstrated success managing a team of 5+ engineers for at least 2 years (managing timelines, performance, and hiring). You know how to transition a team from 'startup chaos' to 'structured agility'. 

● Full-stack Authority: Deep expertise with Javascript, Node.js, MySQL, and Python. You must have world-class expertise in at least one area but possess a solid understanding of the entire stack in a multi-tier environment. 

● Architectural Track Record: Has built at least two professional-grade products as the tech owner/architect and led the delivery of complex products from conception to release. 

● Experience in working with REST APIs, Machine Learning, Algorithms & AWS. 

● Familiar with visualization libraries and database technologies.

 ● Your reputation in the technology community within your domain. 

● Your participation and success in competitive programming.

● The "Pack Leader" Mentality: You are competitive, but you understand that your team's win is your win. You shift from getting a dopamine hit from solving a bug yourself to getting a hit from unblocking your team to solve ten bugs. 

● High Ownership of Outcomes: You don't just care that the code was written; you care that the feature was delivered, works for the customer, and didn't break production. You expect very highly of yourself and being less than ideal anywhere almost pains you. 

● Resilience: You possess the mental endurance to push through complex technical constraints and tight deadlines without losing your cool. 

● Uncompromising Values: On the other side, there is only one thing that we care for apart from performance - your values. We have room for mistakes on the performance side, we have no room for mistakes on your values.

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
