Software Development Engineer
What you'll do
Be the dedicated engineer for one of our clients. Learn their business, find what to automate, and build it.
Build automations, integrations, and web apps on whatever the client runs business platforms like the Zoho suite, cloud services like Azure, and custom apps where needed.
Work with APIs every day: connect systems, move data, make tools talk to each other.
Own work end to end: hear the problem from the stakeholder, build the solution, ship it, demo it, support it.
Resolve client tickets and bugs fast. Keep their systems and data healthy.
Write things down: clear docs, clear updates, clear commit history.
What we're looking for
2–5 years shipping software that works and being able to read it, debug it, and stand behind it.
Strong with REST APIs and integrations between systems.
Happy working inside business platforms (Zoho, Salesforce, or similar). Much of the leverage in this role lives there, not in custom code.
You can sit in a call with a non-technical client, understand the real problem, and come back with a working solution.
Self-driven. You'll often be the only engineer on a problem.
Why you'll love this role
Full ownership from first call to delivery you run projects, not just a ticket queue.
Direct access to clients and leadership. Your decisions ship the same week.
Constant variety: new systems, new problems, new builds.
We’re building the future of AI-powered sales enablement.
PitchSense AI is a flagship product within our portfolio of AI-driven Sales and Marketing solutions.
We blend conversational intelligence, generative AI, and behavioural analytics to help people master persuasion through real-time AI simulations.
Why PitchSense AI
Working here means joining a small, fast-moving team that lives at the frontier of applied AI.
You’ll:
- Build in a high-pace, high-learning environment where ideas ship fast.
- Tinker with cutting-edge AI tools, agents, and large language models (LLMs) daily.
- Prototype novel ways to combine speech, emotion, and reasoning into human-like training experiences.
- Learn across multiple domains — engineering, design, analytics, and product.
- Work directly with the founding team on problems no one has solved before.
This is not routine work — it’s an opportunity to shape entirely new experiences in human-AI interaction while growing faster than you ever have before.
