About the company
Incluence is a law firm for FinTech, Crypto, and High-Risk businesses: licensing (VASP, EMI, PSP, MiCA), company formation, banking and merchant accounts. Real clients, real licenses, real money — we don't sell vapor, we solve regulatory problems clients can't solve without us.
Marketing doesn't exist yet as a proper function. We're looking for someone who will build it from zero: get the first results done by hand, then build the team that scales brand awareness and lead flow.

What will be in your zone of responsibility

Months 1-6 (operational phase):

• Full audit of the current state — website, SEO traffic, CRM, what's already converting and what isn't — documented and presented to the CEO
• Brand awareness and positioning strategy built from scratch
• Hands-on launch of targeted advertising and first performance channels — you do it yourself first
• First thought leadership pieces and media relations
• Clean handoff of leads into the CRM with no data loss — coordination with Sales
• Getting the company visible in AI search (ChatGPT, Perplexity, and similar) for relevant queries

Months 6-12 (scaling phase):

• Hiring and developing the first marketing team (1-2 people)
• A steady pipeline of PR and content, not one-off spikes
• Representing the company at industry conferences
• Predictable lead flow with regular reporting to the CEO

How we'll measure results

• The main metric is brand awareness and the volume of qualified leads in the CRM, not publications for their own sake
• Leading indicators: brand reach and mentions, traffic from performance channels, leads per week
• Lagging indicators: growth in brand awareness/share of voice, lead-to-pipeline conversion (per Sales data), PR/thought leadership placements per quarter

What we expect

• 6-10 years in marketing, 2+ years at Head/Director level with hands-on ownership, not only team management
• Experience building marketing from scratch — no existing team, no existing brand, no historical data to work from
• Full-cycle experience: brand/PR + performance advertising + lead generation, not just one of these
• Background in B2B where the sale is built on trust and expertise (legal, consulting, compliance, fintech companies)
• Fluent English (C1+) — for negotiations with international media and partners
• Self-starter — you set your own tasks, you don't wait for micromanagement

Nice to have

• Experience in crypto, fintech, or another regulated industry
• Personal contacts in industry media
• Experience speaking at industry conferences

What we offer

• Format: full-time, fully remote
• Salary and bonus — discussed individually based on experience
• Direct access to the CEO, no corporate layers or approvals

• Collaborate with fellow analysts to evaluate performance across key platforms — including Google Analytics, Adjust, AppsFlyer, Google Ads, Meta, and Criteo — and translate findings into actionable business recommendations.
• Contribute technical expertise and business judgment to deep-dive analyses and executive reports for senior leadership, and lead cross-functional projects end to end, managing timelines, risks, and stakeholder communication.
• Leverage AI tools and automation to increase the efficiency, quality, and scale of analytical work — from data preparation and insight generation to reporting and stakeholder communication.

Requirements:

• 5+ years of experience in marketing analytics, ideally within online marketplaces or B2C/B2B digital businesses, with a strong understanding of online and app marketing, campaign optimization, and budget allocation.
• Experience supporting large-scale data integration projects, mergers and acquisitions, or complex organizational integrations, including data migration, KPI harmonization, reporting consolidation, and stakeholder management.
• Proficiency in SQL and hands-on experience building data pipelines and ELT workflows using tools such as Airflow and dbt, with familiarity across cloud data platforms such as BigQuery, Redshift, or Snowflake.
• Strong experience with BI and dashboarding tools (Tableau, Amazon QuickSight, Power BI, or similar), combined with a solid understanding of data visualization best practices.
• Deep understanding of Google Analytics, mobile measurement platforms (Adjust, AppsFlyer), and major advertising platforms (Google, Meta, Criteo), including tracking implementations and reporting structures.
• A proven track record of independently leading cross-functional analytics initiatives across multiple business units and navigating complex stakeholder environments during periods of organizational change.
• A proactive approach to integrating AI tools into analytical workflows, with genuine curiosity about how AI can improve the speed, quality, and impact of analytical work.
• Excellent verbal and written English skills.
• Ability to work within the Toronto, Canada timezone (EST/EDT) and collaborate effectively with distributed, international teams.

Nice to have:

We're looking for a Senior Django / JS Engineer with deep Django expertise and server-rendered frontend skills to take full ownership of the core web platform. Concretely: the Django backend, the REST API, the async job layer, the access-control model, and the dispatcher dashboard that operators rely on 24/7. You will work alongside the Lead and the CTO while taking ownership of the entire stack.
 

You own the platform end to end. Day to day: you build features from the core Django backend and REST API to the server-rendered dashboard and telemetry visualizations, using Celery, Redis, RBAC, and audit logging throughout the platform.
 

One thing to be clear about: commands issued through this platform reach live power plants. That is why access control and audit logging are must-haves here, not a checkbox.

What you'll do

• Develop and own the core Django application end to end: Django backend, REST API, server-rendered dashboard, async job layer, and access-control model
• Design and optimize ORM queries - and know what SQL your querysets actually produce
• Write and deploy migrations against live schemas without downtime
• Build and maintain the Celery layer: task design, periodic jobs, retries, idempotency, queue routing
• Build and maintain dispatcher-facing dashboards and telemetry visualizations
• Design and enforce the RBAC model across the full stack
• Build audit logging as a tamper-evident trail: who, what, when, from where, with what result
• Work in a Spec-Driven Development workflow, treating OpenAPI/Pydantic specifications as the source of truth for API contracts and UI state

Must have

• 5+ years of production experience with Django: This is the core of the role. The interview will go deep into:
  • ORM: Query optimization, select_related/prefetch_related, annotations, and deep understanding of generated SQL.
  • Migrations: Safe deployment on live schemas without downtime.
  • DRF: Serializers, viewsets, permissions, and versioning.
  • Django Internals: Signals, custom management commands, and leveraging the admin as a tool.
• 3+ years of production experience with Celery & Redis: Mandatory, not "used it once." Task design, periodic jobs (celery beat), idempotent tasks, retries, queue routing, and Redis strategies (cache invalidation, TTLs).
• RBAC & Audit Logging: Designing role models (dispatcher/operator/admin) on the principle of least privilege. Every command must be logged—who, what, when, result—as a tamper-evident audit trail for live power plants.
• Full-Stack UI/UX: You own the "face" of the EMS platform.
  • SSR-First: You are comfortable in a server-rendered Django environment (template inheritance, custom tags/filters).
  • Vanilla Fundamentals: Strong grasp of modern CSS (grid/flexbox) and semantic HTML.
  • Data Visualization: You must be able to implement or adapt charting libraries (amCharts/ECharts) to visualize time-series telemetry.
  • AI-Driven Frontend: You treat UI as a spec. You use AI to generate boilerplate templates and interactivity, allowing you to focus purely on the UX reasoning and complex data representation rather than manual DOM manipulation.
• Engineering Rigor:
  • PostgreSQL: Indexes, transactions, and reading query plans.
  • Testing: Pytest, writing testable code for views/serializers/tasks.
  • English: B1 (documentation, written communication).
• Spec-Driven Development (SDD): You treat specifications (OpenAPI/Pydantic) as the source of truth for both API contracts and UI state.
• Agentic Pipelines: Experience building or using agent-based workflows (e.g., CrewAI, LangGraph) to automate backend engineering, deployment, and UI boilerplate generation.

Nice to have

• Frontend & UX: amCharts (v5) expertise; HTMX / Alpine.js for SSR-friendly interactivity; experience with UI design tools (Figma/Sketch) for rapid prototyping; Tailwind / Bootstrap or building small design systems; Accessibility (WCAG) and dark-mode optimization.
• Backend & Infrastructure: FastAPI / Pydantic v2, asyncio; Docker / Docker Compose, CI pipelines; TimescaleDB or MongoDB.
• Domain & Standards: Industrial connectivity (OPC UA, Modbus); Energy domain (PV / BESS); Security-standard exposure (IEC 62443, NIS2).

• Формування та підтримка єдиного технічного бачення для продуктів у межах проєкту.
• Проєктування та розвиток архітектури інформаційних систем, їхніх модулів, моделей даних та інтеграцій.
• Технічна координація окремих команд розробки, що працюють із Golang, Java та Angular.
• Визначення та впровадження єдиних технічних стандартів для API, інтеграцій, роботи з даними, обробки помилок, логування та observability.
• Декомпозиція функціональних, нефункціональних і безпекових вимог у технічні рішення та задачі для команд.

• Проєктування security architecture: автентифікація, авторизація, контроль доступу, service-to-service security, audit trail, secrets management і захист чутливої інформації.
• Визначення контролів безпеки для ключових компонентів систем та участь у threat modeling.
• Проєктування і контроль взаємодії між відкритими, конфіденційними та захищеними контурами.
• Погодження API-контрактів, моделей даних і технічних рішень між командами та суміжними системами.

• Формування технічного roadmap, оцінка складності робіт, визначення залежностей та управління технічними ризиками.
• Контроль технічного боргу та планування його системного скорочення.
• Взаємодія з Product Owner, Project Manager, бізнес-аналітиками, QA, DevOps, командами інформаційної безпеки та представниками Замовника.
• Підготовка та актуалізація архітектурної, технічної й security-документації, включно зі схемами взаємодії, ADR та API-специфікаціями.
• Технічний супровід тестування, навантажувальних перевірок, ЦПБ/ІБ-перевірок і приймання систем.
