About Gazer

Gazer is a manufacturer of automotive security systems — including immobilisers, dash cameras, and related electronics. The company develops and distributes its product line across multiple markets, working with dealers, installers, and fleet operators. As the business scales its presence across the globe, this role supports the growth of Gazer's social media content output across TikTok, Instagram, and YouTube Shorts.

Web: gazer.com

Role Purpose

This is a creative role. The input is raw studio footage of cars — clean, static, well-lit. Your job is to turn it into short-form content (15–60 seconds) that performs on TikTok and Instagram Reels: hooks that hold attention, cuts that land on the beat, formats that match what the algorithm is rewarding right now. Rhythm, timing, and trend awareness matter more here than technical polish.

Key Responsibilities

• Edit short-form videos (15–60 sec) from studio automotive footage for TikTok, Reels, and YouTube Shorts
• Select and sync music and sound effects; match cuts to beat and current platform trends
• Apply colour grading, motion graphics, and text animations — price callouts, feature highlights, detail emphasis
• Adapt a single source asset into multiple formats and aspect ratios (length variations, vertical/horizontal)
• Monitor TikTok and Instagram trends continuously — transitions, sounds, formats — and bring new ideas to the team proactively
• Maintain brand consistency and meet the team's content release cadence

Requirements

• Portfolio of dynamic short-form edits for TikTok or Instagram — automotive content is a plus but not required; the editing style matters more
• Strong command of at least one professional editing tool (Premiere Pro, CapCut, DaVinci Resolve, or equivalent)
• Developed sense of rhythm and timing — you edit to music, not just alongside it
• Clear understanding of short-form video mechanics: the hook, attention retention, pacing, and what makes people watch past the first three seconds
• Self-directed: able to take raw footage and propose edit concepts without a shot-by-shot brief
• Conversational English for day-to-day team communication

Nice to Have

• Experience editing content for automotive channels, dealerships, marketplaces, or catalogues
• Familiarity with automotive content formats: detailing, test drives, before/after, comparisons
• Basic audio design skills: mixing, level normalisation, sound layering
• Experience managing high-volume output — multiple edits per day from a continuous stream of source material

Working Conditions

• Format: fully remote, full-time
• Competitive compensation, discussed individually

Final-stage assessment: Candidates who reach the final round will edit one short-form video from provided raw studio footage.

Room to grow and expand your role over time

We are looking for a Wordpress Developer to basically work with Wordpress themes and do basic wordpress development work.  We do not need someone who is a strong programmer other than maybe knowing some basic PHP that is useful for the development process.  Even if one does not know PHP but is very good at Wordpress we are interested in talking to you. You should be proficient creating new pages and editing existing work using elementor and template systems. You will report to someone who has a working knowledge of Wordpress and the design process.  If you are also good at UI/UX deign and proficient at Canva or Figma, this would be a plus but is not necessary.  It is important that you are able to help train other team members on Wordpress as well.  We have a great team and have been working with colleagues in Eastern Europe (particularly in Ukraine) for over 10 years.  People find working with us rewarding and interesting.  

Why This Role

You'll build systems that move real money and digital assets — exchanges, payment rails, crypto processing, and OTC desks — where every decision touches security, latency, and correctness. The

problems are real: real adversaries, real settlement guarantees, real users who can't afford downtime. If you want ownership over production fintech infrastructure rather than another CRUD app, this is that.

You'll join a small team shipping to production frequently, owning features end-to-end across our backend services, customer-facing products, and internal back-office tools.
 

Tech Stack

- Backend: Python 3.12, FastAPI, SQLAlchemy + Alembic, Gunicorn/Uvicorn

- Frontend: React 18 + TypeScript, Vite, Tailwind + shadcn/ui, React Query

- Back-office: React 18 + TypeScript, Vite, Tailwind + shadcn/ui

Databases: PostgreSQL 17 + MongoDB
 

What You'll Do

- Own full-stack features from spec through deployment, monitoring, and iteration

- Build and maintain FastAPI services handling payments, exchange, and crypto-processing flows

- Develop responsive interfaces for both customer-facing products and internal back-office tools

- Model and optimize data across PostgreSQL and MongoDB; manage migrations with Alembic

- Integrate third-party payment, banking, and crypto APIs

- Bake security and compliance into everything — you'll be trusted with money-handling code, often without a dedicated QA safety net
 

Must Have

- 5+ years full-stack experience, with at least 3 building production backend services

- Strong command of Python / FastAPI and React + TypeScript

- Solid experience with PostgreSQL (relational modeling, query optimization)

- Advanced, daily use of AI tools in your workflow — you use assistants like Claude, Copilot, or

- Cursor to scaffold, refactor, and review code, and you can judge when to trust their output and when

to discard it

- Genuine independence — you take ownership, make sound calls, and drive work forward with minimal oversight (essential on a remote, fast-moving team)
 

Bonus

- Experience with MongoDB and the wider frontend stack (Vite, shadcn/ui, React Query)

- Fintech background — payments, banking, PSP, or exchanges

- Crypto / digital assets — exchanges, processing, custody, or OTC (a strong extra plus)
