The work

Three lines of work, one engineering team. Most engineers touch all three.

Products with real users

Fint, Desk, Cybe Social and WhatsApp CRM, with problems like bank matching and GST summaries.

Read more about Products with real users

Fint (invoicing, expenses, banking and GST for Indian businesses), Desk (CRM and project management), Cybe Social (social media scheduling) and WhatsApp CRM. The problems are concrete: matching bank lines to invoices, building GSTR-1 and GSTR-3B summaries, fanning one post out to many accounts and tracking which copies failed, and letting an AI agent propose a record while making sure no money is recorded until a person confirms it.

Client AI systems

Agents and automation for clients, such as WhatsApp lead pipelines, OCR and marketing dashboards.

Read more about Client AI systems

AI agents and workflow automation for businesses in India, the UK and beyond. Typical builds: a WhatsApp lead pipeline on n8n and the WhatsApp Business API that qualifies leads and routes them to sales reps; an OCR pipeline that reads invoices, IDs and forms and sends low-confidence fields to a person; a marketing dashboard that joins Meta Ads, Google Ads, GA4 and CRM data in BigQuery. AI systems are scored on a test set before handover.

What we look for

What tells us most about an engineer.

Work you can show and explain

A repo, app, notebook or board, and which part was yours.

Read more about Work you can show and explain

A repository, a deployed app, a notebook, a write-up or a board you wired up. Tell us which part was yours, what broke, and what you would change now.

Hands-on with the stack

Python, JavaScript, n8n, LLMs, OCR and SQL. Nobody needs all of them.

Read more about Hands-on with the stack

Python, JavaScript and Node.js, n8n, LLM APIs and open-weight models, OCR engines, and SQL databases such as MySQL. Nobody needs all of them. Say which ones you have used on something real.

Measuring before claiming

Show a time you measured something instead of assuming it.

Read more about Measuring before claiming

We write the test set before we tune the prompt, and we publish benchmarks only with method, hardware, versions and date. Show us a time you measured something instead of assuming it.

Care about failure cases

Ask what happens when input is wrong, an API is down or a model is unsure.

Read more about Care about failure cases

Our systems touch invoices, tax summaries and customer messages. We want engineers who ask what happens when the input is wrong, the API is down, or the model is unsure.

Clear writing

Engineers write client runbooks and lab notes, so plain sentences matter.

Read more about Clear writing

Engineers here write runbooks for clients and will write the lab notes for the R&D / Labs notes section of our blog. If you can explain what you built in plain sentences, show us.
