What is Armory?

What we are building requires hard work, tenacity, ownership, creativity, and way more man-hours than an everyday job.

If you are a savant at what you do, love autonomy, have high agency, and genuinely want to impact the future of this country, we want you to work with us starting yesterday!

Modern conflicts waged remotely demand a radical rethinking of strategy as adversaries deploy inexpensive drones and technology to inflict maximum damage with minimal risk.

If you prefer routine over the dynamic unpredictability of innovation, Armory isn't for you. Our fast-paced environment requires genuine curiosity, resilience, a passion for continuous learning, and comfort with rapid change.

Armory is a new-age defence tech startup building next-generation products to strengthen Indian forces in the modern battlefields.

About the founder

Amardeep Singh is an IIT Bombay alumnus & an aerospace engineer by education. He was a founding member of ideaForge - currently India's biggest drone company & the first drone company to get listed on the Indian stock exchange.

His 16-year entrepreneurial journey is marked by a series of ambitious ventures spanning across diverse tech domains like Drones, Consumer Hardware, B2B SaaS & AI.

Problems we solve

Our country's defence systems, conceived in a bygone era, have been outpaced by the rapid advancements in technology, revealing critical gaps that we, at Armory, are poised to bridge.

At Armory, we identify and solve the most critical, complex & specific challenges in modern warfare. By harnessing the power of artificial intelligence and diving deep into specific problems, we create innovative defence technologies and products that protect our nation and allies.

Why you should NOT join us

If high stakes, tight deadlines, and significant challenges don't excite you, then our mission to revolutionise defence technology might not align with your career goals. We seek individuals who are ready to push boundaries and are motivated by the urgency of now.

Why you SHOULD join us

We offer the opportunity to work on groundbreaking projects that strengthen national defence, supported by a team of A players.

Join Armory if you're drawn to solving hard problems and want to create a meaningful & profound impact on national security.

At Armory, you will do the best work of your life. Period.

Requirements

About this role

You will own the perception and edge AI stack at Armory: data, models and deployment on hardware. The systems you build run in the field, in real scenarios, where reliability is a baseline and a failure has real consequences. This is a builder role. You will train models, write code and ship on real hardware, starting in ambiguity where specs are thin and priorities shift, and turn it into systems that run with clarity and discipline, without losing speed. Experience: 4-7 years.

• Build and train computer vision and multimodal models for detection, tracking and segmentation in real defence scenarios.
• Own the data pipeline: collection, labelling, synthetic data and failure-driven retraining.
• Optimise and deploy models on edge hardware (Jetson, ARM) within strict latency and power budgets.
• Integrate perception with hardware, RF and sensor systems so the whole stack works in the field, not just in the lab.
• Work with hardware, systems and design teams to ship new capabilities, and mentor junior engineers.

Must haves

• 4-7 years building and shipping ML systems, with 3+ years in computer vision or robotics perception.
• Strong Python and PyTorch, with working C++.
• Hands-on with detection and segmentation models (YOLO, RF-DETR, SAM) and fine-tuning them on custom data.
• Edge deployment experience on Jetson or similar: TensorRT, ONNX, quantisation.
• Ownership: you take an ambiguous problem to a working system and explain your trade-offs simply, without ego.

Bonus points for

• Sensor fusion, stereo vision, LiDAR point clouds or SLAM.
• Experience with VLMs or VLAs, ROS and simulation (Isaac Sim, AirSim).
• Drone, UAV or geospatial imagery work.
• Open-source contributions, publications or patents, and a keen interest in defence.

What will make you successful in this role?

• Deep technical expertise, worn lightly. You are exceptional without being cocky.
• Shipping model improvements to production every week.
• Bringing order to chaos without adding bureaucracy.
• Getting models running on real hardware in record time.

How will we set you up for success in this role?

• A live project: You will jump straight into a live project as soon as you join. No dummy or test projects.
• Access to resources: You name it, we will do everything to get it for you. That includes GPUs, data and hardware.
• Supportive team: You will be surrounded by the best minds ready to help you.
• Founder access: You will work directly with the founder on what to build and how to build it.

Tips

Irrespective of whether you apply to Armory or not, some of the following tips will definitely help you in your job search.

How to get hired

• Targeted Applications: Ensure your application is tailored specifically for the job you're applying for by understanding its requirements and showcasing relevant experiences and skills. Apply for THIS job, not some job.
• Quality Over Quantity: Instead of applying to 100 jobs casually, it's far better to apply to 4 seriously.
• Stand out: Most people don't put any effort into applying to jobs; their applications look exactly the same. It's easy to stand out from them just by putting a little effort and showcasing your relevant experience and interest for the said job.

How to NOT get hired

If your cover letter starts with "Honestly, I possess all the skills and experience that you're looking for," then you are not going to make it.

In fact, we wrote a long thread on all the ways you will NOT get hired. https://x.com/singhamardeep/status/1459114743398998018?s=46 We highly recommend that you read it.
