• Measurement & Continuous Improvement
  
  • Develop and maintain a standardized Developer Experience Questionnaire to measure pain points in onboarding, tooling, workflows, and collaboration.
  • Run surveys at key points (post-onboarding, quarterly pulse checks) and track changes over time.
  • Combine questionnaire insights with operational metrics like build times, PR cycle duration, and test reliability to build a holistic picture of developer productivity.
  • Apply the SPACE framework (Satisfaction, Performance, Activity, Communication, Efficiency) to balance hard metrics with developer sentiment and ensure we measure what truly matters.
  • Use findings to prioritize workflow, tooling, and culture improvements across the engineering organization.

Wallet in Telegram is a digital asset solution natively embedded into Telegram’s interface. Backed by The Open Platform, Wallet in Telegram gained 100M+ user accounts in 2024, and aims to make its solution available to all 1BN+ of Telegram’s users. Wallet in Telegram offers a dual-wallet experience with Crypto Wallet (a multi-chain wallet for trading and sending crypto to contacts) and TON Wallet (a self-custodial wallet with access to the TON ecosystem of dApps and tokens).

As our Special Projects Lead, you’re here to put the best of crypto into the hands of a billion Telegram users.

Your focus: sourcing and landing the right partners — the top protocols, products and players — and helping bring them into Telegram’s native crypto wallet. You will drive lead generation and follow-through for the most important integrations in crypto: vaults, staking, swaps, payments, token launches. If it expands what users can do in the wallet, it’s on your radar.

You’ll work with a small, senior team (Chief Strategy Officer & Head of BD) to turn high-value targets into live deals, and keep things running smoothly across legal, compliance, marketing and product.

Responsibilities:

• Hunt down the best protocols, products and services to bring into the wallet — if it’s new and useful or blue-chip and big, you’re on it.
• Run with live deals from start to finish: intros, follow-ups, calls, docs, deadlines — all of it.
• Keep the pipeline sharp: track what’s moving, what’s stuck, what should be eliminated and what’s next.
• Connect the dots across product, legal, marketing and compliance to make things happen.
• Drop quick write-ups that actually help the team move — no fluff, just signal.
• Spot chaos early and bring order fast. No one’s telling you what to do — you figure it out.

Requirements:

• Sharp mind, fast learning curve. You pick things up quickly and get up to speed on unfamiliar topics fast.
• Experience in BD, strategy, or ops — or in any role that demonstrates clear, structured thinking.
• Clear writing, strong instincts, solid judgment. You can be trusted to just figure it out.
• Crypto-native is great, but not required.

Why it is a fantastic opportunity:

• Our business is growing at an exponential scale.
• Non-bureaucratic management that focuses on results.
• Regular performance reviews to assess your progress.
• Remote setup with access to our hubs in Dubai, Yerevan, London and Belgrade.
• Compensation for medical expenses.
• Provision of necessary equipment.
• 20 working days of paid vacation annually.
• 11 days off per year.
• 14 days of paid sick leave to support your health and recovery when needed.
• Access to internal conferences, English courses and corporate events.

We are the Armenian Artificial Intelligence Company (AAIC): a collective of scientists, engineers, designers, and writers. We work globally, creating unique software for diverse clients—from devices that assist professional chefs to city simulations and narrative games.

As we launch new narrative projects, we're expanding our writers' room and seeking a prompt engineer with a passion for fiction to support our writing team.

What we're looking for:

• Hands-on experience with LLM text generation: you regularly work with large language models like ChatGPT or DeepSeek and know how to craft prompts that produce stylistically and factually consistent texts.
• Hands-on experience using LLM for non-generative tasks: you apply LLM for classification or input validation purposes and know how to craft prompts that produce reliable machine-readable output.
• Hands-on experience with coding: you can write simple Python or TypeScript scripts to automate your tasks when needed.
• Hands-on experience in writing: you've created essays, novels, stories, academic papers, or articles—we accept any form of written work in any language (except social media posts, technical documentation, or project briefs).
• You are fluent in English and have excellent written communication skills. Fluent Russian is a big plus.

This position is fully remote with an expected workload of 30–40 hours per week at a rate of $10–15 per hour.

What we will NOT be looking at:

• Years of experience.
• Big names in your CV.
• We'll read the CV if you send it, but it doesn't matter that much in general.

To apply, email Niko with the following:

• An LLM prompt focused on text generation (e.g., generating documents, chat messages, code)
• An LLM prompt focused on classification or validation (e.g., sentiment analysis)
• A piece of practical code that you wrote yourself (doesn’t need to be industrial-grade)
• A sample of your long-form fiction writing (can be in any language).
• A description of the most interesting project you've worked on (doesn't need to be commercial or large-scale).

As an AI company, we're very good at spotting LLM writing. A human will read your application and always respond by hand, so please extend the same courtesy.

What's next?

1. A call where someone will introduce our company and you'll have an opportunity to ask questions.
