What we are building requires hard work, tenacity, ownership, creativity and way more man-hours than an everyday job.
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.
Requirements
You will be responsible for both front-end and back-end development of robust, secure, and user-friendly applications tailored for defence technology.
- Design, develop, and maintain scalable web, mobile & desktop applications.
- Previous experience with Hardware, Software, and/or IoT is a plus.
- Collaborate with cross-functional teams to define, design, and ship new features.
- Ensure the performance, security, quality, and responsiveness of applications.
- Write clean, maintainable, and efficient code with a focus on security best practices.
Architect and build scalable full-stack applications (web-first, with desktop extensibility via Tauri/Electron where needed), with 3–5 years of hands-on professional experience across frontend and backend systems.
Build and maintain secure, production-grade APIs in Python (3.10+) using FastAPI, typed end-to-end with Pydantic models for every request, response, message, and config object. If you don't use Pydantic everywhere, this isn't the job for you.
Deep, working fluency with asyncio, not just async/await syntax, but event loop mechanics, task management, cancellation, backpressure, and debugging async deadlocks under production pressure.
Design and implement real-time data pipelines using WebSockets, SSE, and message buses (MQTT, JSON-RPC over multiple transports) for live sensor and telemetry data.
Comfortable working close to hardware, integrating software systems with IoT devices, SDR pipelines, microcontrollers, and embedded subsystems over serial, USB, or LAN.
Design PostgreSQL schemas with performance, integrity, and operational scale in mind; understand indexing, partitioning, and time-series data patterns.
Own CI/CD pipelines, containerisation (Docker), testing (pytest with async test coverage), and release workflows on Linux
Linux-native: comfortable administering Ubuntu/Debian systems, writing systemd services, configuring networking, and diagnosing issues without a GUI.
AI-native in the right way, you use tools like Claude the way a sculptor uses a chisel: precise, intentional, and with a clear mental model of what the model will produce and why. You can articulate exactly what a model will generate, where it will hallucinate, and when not to trust it. You do not ship vibecoded slop.
Experience with Tauri (Rust + WebView) for packaging desktop/kiosk Linux applications
Familiarity with SDR concepts, I/Q data, signal processing pipelines, RF subsystem integration
Geospatial data handling, UTM, MGRS, GeoJSON, Mapbox/Leaflet
uv for Python packaging and dependency management
Experience with data-dense operational UIs, not CRUD dashboards, but systems where operators make real-time decisions under pressure
What will make you successful in this role?
- Deep Technical Expertise in your domain.
- Shipping features weekly.
- Knack of integrating software for hardware systems in record time.
- Getting s**t done.
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.
- Supportive team: You will be surrounded by the best minds ready to help you.

Irrespective of you applying at 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 efforts in 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 you to read it.
