Planning to Apply? Consider this:
Make sure you go through this section very carefully before applying. Here are the most crucial aspects on which we evaluate on:
1: FIT: “We’re on a crusade for something greater than any one of us”!
We are a tight-knit team that works and plays together where ‘fit’ is the most important point that you need to keep in mind while evaluating us- we will be spending a majority of our time together, in office, on calls, even weekends (sometimes) so you’ll really need to assess whether this is the right place for YOU to be in. Are you able to relate to or feel passionate about the problems we’re solving?
2: INTENT: “You won’t just be working with us, you would be investing in us!”
‘Why’ do you want to work with us? Why an early stage startup? Why Original4Sure? We are an industrious team, working tirelessly to achieve our goals so the work hours will be long and with it will come with a steep learning curve. Joining an early stage startup also means you’ll be asked to take on new things with little guidance and you’ll have to figure stuff out on your own, and in doing so, help shape the future of the company. Does that sound scary, exciting, both?
3: CAPABILITY: “Get work done!”
As long as you are working as hard as you can and giving it your best all day, every day, we will get along just fine. No one ever built one of the most valuable businesses in the World without the core team having to make a few sacrifices along the journey. It could be lesser time spent with your family or loved ones or finding lesser time to do to watch TV shows! But that's a call you need to make.

About the company
Octobotics Tech is an early-stage robotics engineering startup focused on building advanced robotic solutions for the maritime and oil & gas industries, where inspection and maintenance are complex, risky, and costly.
The company is developing a next-generation marine and aerial robotic platform with modular manipulators designed for autonomous inspection and non-destructive testing (NDT), even on heavily corroded surfaces. The platform supports techniques such as Eddy Current and other NDT methods, and the core technology is already at a matured stage, not just experimental R&D.
Alongside platform development, Octobotics delivers robotic inspection and maintenance services, using specialized robots to navigate challenging environments and perform precision-driven tasks that reduce human risk, downtime, and operational costs. The team also builds custom robotic solutions, working closely with clients to address specific operational and infrastructure challenges.
Backed by a pre-seed round from a Hong Kong–based investor, Octobotics operates as a flat, non-toxic organization that values unconventional thinking, ownership, and hands-on problem solving. The company is now hiring its first core team members to help push the boundaries of applied robotics in real-world industrial environments.
