About the job

Requirements
  • Have at least 5 years of visual design experience across agencies, studios, or in-house teams.
  • Provide a portfolio demonstrating strong creative craft and range across performance ads, social, motion, campaigns, and other marketing creative.
  • Have several years of experience creating static work by hand before AI image generation became available in 2022, with portfolio evidence of composition, typography, image-making, and considered design choices.
  • Be comfortable with high-velocity creative production and producing a high volume of ads rather than spending weeks perfecting a single asset.
  • Be able to work within an established brand system and identify when to extend it.
  • Have strong illustration and art-direction skills and be able to turn a short-deadline creative request into a shippable asset.
  • Use AI in the design workflow or actively keep up with AI for ideation, generation, or automation, and be able to demonstrate experiments and lessons learned.
  • Have hands-on fluency in Figma and Adobe tools, including Photoshop, Illustrator, and After Effects or equivalent; be comfortable with motion and short video.
  • Be self-managed, communicate clearly in writing, and give and receive feedback constructively.
Responsibilities
  • Create high-volume, mostly static ad creative against real budget, working with the Creative Strategist; ship, learn, and iterate quickly.
  • Adapt and extend the visual brand system through storyboards, art direction, and illustration, using the brand book and improving the system through its application.
  • Produce campaign and social assets from daily briefs with quick turnarounds, including static creative, simple animations, short video, and blog or editorial work.
  • Create decks for sales, customer success, and founders, and build templates the team can use without breaking the brand.
  • Design event materials including booths, signage, swag, and screens for digital, print, spatial, and on-site use.
  • Redraw product screens for marketing use, including hero images, comparison shots, and walkthroughs; the role does not perform UI work.
  • Roll out the brand across decks, ads, social, and content, and ensure new decks use the templates and event materials align with the brand.
  • Ship a campaign asset or ad set to production on day one, using the brand book and Figma library.
  • Work with Growth on ads and performance creative, with additional ownership across content and events, and partner with the Founding Designer on strategic brand system and identity-extension projects.
Desired Qualifications
  • UI/UX experience is a plus but is not required.
  • Familiarity with Claude Code or Cursor and interest in vibe-coding.
  • Having shipped a personal product, whether large or small.
  • Experience shipping landing pages end-to-end with Webflow or Framer; web work is a plus, not core.
  • Experience designing for live events at scale.
  • Experience running a studio or freelance practice.
  • Experience building internal AI tooling for a design team.

Simplify's Take

What believers are saying

  • Viktor crossed $15M run-rate within ten weeks and 2,000 organizations by May 2026.
  • June 2026 Teams launch opened Microsoft’s much larger installed base beyond Slack users.
  • The product returns PDFs, spreadsheets, dashboards, apps, and code, enabling measurable business output.

What critics are saying

  • Microsoft launched Copilot Cowork in 2026, directly targeting Viktor’s core Teams workflow wedge.
  • Fortune reported a skull-emoji reaction during a layoff announcement, exposing unsafe behavior.
  • Slack and Teams control distribution; a platform change can crush Viktor’s standalone access.

What makes viktor.com unique

  • Slack-native and Teams-native, Viktor executes tasks, not just chat, across 3,000 tools.
  • It reported $20M ARR in June 2026, after launching publicly in February 2026.
  • Accel, Stewart Butterfield, and Cal Henderson back Viktor’s workflow-embedded AI coworker thesis.

AI startup Viktor raises $75M to embed virtual 'coworker' in Slack and Teams

Viktor, an AI startup co-founded by former Meta engineers Fryderyk Wiatrowski and Peter Albert, has raised $75 million in a Series A round led by Accel Partners. The funding included participation from Bek Ventures, Kaya VC and Tenacity Capital, plus angel investors including Slack co-founders Stewart Butterfield and Cal Henderson. The company has developed an AI agent that operates as a virtual coworker within Slack and Microsoft Teams, connecting to business systems like Google Drive, Meta Ads and Shopify. Viktor can execute tasks, build internal apps and suggest workflow improvements. Three months after launching publicly in February, the startup reports $15 million in annualised revenue and over 2,000 organisations using its product. The company offers a free tier alongside credit-based subscriptions, with some teams spending more on Viktor than on junior employees.
