Drone startup | Product Engineer (Typescript) | 1 day/week in the office (London, UK) | Citizens of the UNITED KINGDOM only

You'd be working with engineers who previously worked at Google, Amazon, Helsing, Darktrace and an F1 team. We build drones (software and hardware)

We're looking for engineers that straddle real world problems, and use technology as a solution. We prefer personal projects or relevant hobbies, not hard leetcode questions. We value collaboration: pair programming, discussing, teaching and learning from others. We're looking for mission-driven engineers. People who see problems in the world and want to help solve them.

You'd be working with me to build the most intuitive, performant, and modern mission planning and flight monitoring software for drones, and related applications (tools for drone design and manufacturing). For my project, we use React, Tailwind, Node, drizzle-orm, Postgres, SQLite, deck.gl, Python, FastAPI, asyncio, and more. You're allowed (and compensated) to use AI services.

Because we are a small team, you will be noticed and rewarded for performance.

*Please don’t apply if any of these resonate:*

• You prefer narrow ownership—“I only touch the backend or the code I've written”.

• You think it's more about "who you know, not what you know".

• You haven’t actively learned a new tool or hobby in the last year.

If interested, email my temporary email: hn-july25@mail.orth.uk with your CV and some personalised information about why you'd be the right fit.

Looking for a founding engineer to help us go 0→1. You’ll own architecture, ship fast, and build agent-based features with LLMs. Full-stack or backend-leaning ideal. You like product. You’ve built things. You want real ownership. You care about solving problems that actually matter.

Culture is low-ego, high-autonomy. Equity is meaningful.

Krystof Hilar, Co-Founder & CTO

Big Picture AI Consultants is hiring Expert Software Developer Wanted: Tiny Team. Big Upside.

We’re building a working product: an AI voice agent for restaurants that answers phones and takes orders. The prototype is already in action—but it’s only working 96% of the time. We need someone to help bring it to 100%.

You’ll be joining a lean team with product vision, business execution, and marketing muscle already in place. We need someone who can build effectively and reliably.

We’ve already wasted time on 10+ “developers” who: • Can’t answer questions directly • Don’t communicate or follow up • Ghost when it’s time to deliver • Aren’t cooperative or team players

We’re done with that. If you’re not reliable, please move on.

What We’re Looking For: • A professional developer who wants to build something once and benefit long-term • Open-minded, direct communicator • Works within agreed timelines • Handles full-stack or backend infrastructure • Experience with voice AI a plus (not required)

Opportunity: • You can work part-time at first (estimated 200 hours for initial version) • Revenue expected within 60 days after platform completion • Targeting $10M+ potential within 3 years • We’re already using tools like OpenAI, LangChain, ElevenLabs, N8N, etc. • You focus on the build. We’ll handle the rest.

Interested?
