Are you looking for a super-challenging role designing backend systems that scale to 1000+ TPSs in one of India's fastest growing, profitable near-Unicorns with businesses spanning Lending, E-comm and UPI? Then this is the role for you.

Client Company is a profitable, rapidly scaling unicorn which is extremely well capitalized. Client has a very strong moat in the consumer lending space on the back of which it is entering into additional large markets such as E-comm and UPI.

Client company is now entering its next phase of growth from a fast-scaling startup to a robust, high-scale financial platform serving millions of users daily.

You'll design systems built for 10x100x growth, make the key technical trade-off calls, and stay deeply hands-on. Beyond building, you'll mentor engineers and work directly with founders and product teams to translate business goals into scalable, reliable systems.

This role is an opportunity to:

• Shape the next-generation architecture for a high-throughput fintech system
• Build systems designed to scale 10x100x from current volumes
• Solve real-world problems across performance, reliability, and financial-grade security

Responsibilities

• Design and evolve the platform architecture to support 10x100x growth
• Own systems end-to-end from the first design decision to production impact
• Lead system design discussions and set the long-term technical direction for the platform
• Identify scale bottlenecks early and drive solutions
• Mentor and elevate engineers through design reviews, code quality, and architectural thinking
• Partner directly with founders and product teams to turn business priorities into scalable systems
• Operate with high ownership in a fast-paced environment where priorities evolve quickly
• Drive projects independently own timelines, coordinate with teams, and see delivery
• Conduct rigorous code reviews and champion engineering best practices across the team
• Proactively identify gaps in the system and come up with concrete approaches to address them
• Solve technical problems across the company not just confined to a single pod
• Challenge existing architecture with data and reasoning push back when its the right call, and drive adoption of better approaches.

Requirements

• 7-12 years of experience in backend or platform engineering
• Strong computer science fundamentals (preferably from IIT, BITS, NITs)
• Strong proficiency in backend development (Node.js, Java, Go, or equivalent)
• Proven experience scaling systems through high-growth startup phases (1→10 or beyond)
• Track record of building and owning critical platforms or systems from scratch
• Exposure to high-volume transactional systems; fintech or lending is a strong plus
• Bias for action - moves fast, makes sound decisions, owns outcomes end-to-end
• Comfortable navigating ambiguity and evolving priorities in a startup environment
• Strong problem-solving skills ability to break down complex technical challenges and arrive at pragmatic, well-reasoned solutions
• Hands-on experience with platform engineering developer tooling, shared services, infrastructure abstractions, or internal platforms

What we're looking for

Hanomi builds software that automatically generates 2D engineering drawings from 3D CAD models. We've raised venture funding, have paying manufacturing customers across India and internationally, and just shipped drawing automation to production. We're a team of 8 engineers moving fast toward scaling this to thousands of drawings per day. You'll work on real parts that go to real factory floors - where a wrong dimension means a scrapped part and a missed shipment. It's demanding work with real accountability, but if you're the kind of person who gets fired up by solving hard problems across multiple technical domains and seeing a team ship consistently, you'll fit right in.

We're looking for a person to lead engineering execution. This role is on-site at our Bengaluru office.

You'll work directly with our CTO to turn product priorities into shipped software. This isn't a management-from-a-distance role - you'll plan sprints and hold people accountable, but you'll also roll up your sleeves to debug, brainstorm algorithmic approaches, and review PRs with enough depth to catch when something doesn't fit.

Engineering Lead:

In this role, you will:

Own engineering execution across the team:

·        Plan sprints, set timelines, track progress, and hold people accountable

·        Run gate reviews before production deploys and flag risks before they become misses

·        Coordinate between our algo team and platform team

·        Be the person who makes sure things ship by being close enough to the work to know when something's going wrong

Roll up your sleeves and build alongside the team:

·        Debug production issues together with engineers, not delegate and wait

·        Brainstorm algorithmic approaches and review PRs deeply enough to catch integration issues

·        Jump into the codebase when something's blocked, you're not above writing code to unblock a sprint

Bring technical depth across algorithms and platform:

·        Understand mechanical engineering concepts well enough to question whether an approach makes sense for different manufacturing processes

·        Have experience scaling platforms - deployment pipelines, reliability, monitoring, the infrastructure that keeps a product running for paying customers

·        Ideally have worked on desktop applications or integrations with CAD software APIs

Make the team better over time:

·        Give direct, specific feedback - including the uncomfortable kind

·        Know when an engineer needs clearer specs vs more autonomy vs a push

·        Identify process gaps and fix them without adding bureaucracy

Note given that we are a startup, the exact job match will depend on your skills and interest (there is always too much to do!).

Requirements:

·        5-7 years in software engineering, with experience leading teams of 5–10 engineers

·        Strong Python - comfortable reading and contributing to algorithm code

·        Experience scaling platforms that serve real customers with reliability requirements

·        Exposure to mechanical engineering or CAD/PLM domains - you don't need to be a mech engineer, but you should understand what an engineering drawing represents and why correctness matters

·        Desktop application development or API integrations with CAD software is a strong plus

·        You still enjoy building - this is a hands-on leadership role where you're expected to contribute technically

·        Startup experience preferred - you know the difference between useful process and process theater

Preferred Qualifications:

·        Background in 3D / manufacturing

·        Experience with computational geometry / 3D modelling workflows 

·        You've managed engineers who are deep specialists and earned their respect through technical credibility, not just title

·        You use AI tools in your daily workflow - Claude Code, Cursor
