Tessl is a fast-growing Series A startup based in London, founded by Guy Podjarny. We’ve raised over $100M from world-class investors including Index Ventures, Accel, GV, and Boldstart, and in 2025 we were ranked #2 in Sifted EU’s B2B SaaS Rising 100 and #20 in Sifted's AI 100.
At Tessl, we are building the context layer for AI coding agents, and a platform for AI-native software development. As an early member of the team, you’ll help shape how we build, scale and support a company operating at the edge of AI and software development.
ABOUT THE ROLE
Content ships fast across engineering, marketing, community, and DevRel. This role is the connective tissue that makes that possible: owning the comms calendar, publishing content, coordinating creative assets and social comms, moderating comments in channels like YouTube, and making sure content reaches the channels and communities where our audience is. This is a 6-month fixed-term contract (FTC).
This is an execution and coordination role, and a great entry point into B2B marketing at an AI-native company. It also includes building automations for this work using Tessl's own Dark Factory, with support from our GTM engineer, so repeatable production tasks get systemized rather than repeated by hand.
WHAT YOU'LL DO
Content calendar & publishing workflow
Own the content calendar end to end and keep it current after every planning meeting
Coordinate the publishing pipeline: chase drafts, request design assets with adequate lead time, and hold authors accountable to deadlines
Publishing & distribution
Own the social media calendar and publish posts (LinkedIn, Twitter/X, Reddit, Discord) using pre-generated copy and UTM links.
Publish videos to YouTube with pre-written descriptions and links; manage thumbnails and playlist placement.
Cross-post published content to branded third-party channels (Reddit, Hacker Noon, Dev.to) with canonical backlinks and UTM tracking, following the existing UTM taxonomy.
Build and maintain an automation that surfaces relevant developer community threads (Reddit, Hacker News) and drafts contextual posts back to published content, pushing them to Slack in real time so DevRel and community-trusted individuals can review and post under their own name, this role builds the surfacing and drafting mechanism.
Produce a monthly developer-community signal report (notable threads, questions, sentiment) for DevRel, Product, Marketing, and Sales, which will become an automated workflow feeding the same real-time Slack surfacing above.
Moderation & community response
Respond to comments and questions on social and YouTube (triage or use internal tooling)
Moderate comments across channels: remove spam/abuse, flag anything sensitive or reputationally risky before responding (auto-hide is enabled for malicious comments)
Pull noteworthy comments, questions, and feedback into Slack weekly, so the team sees what the audience is saying without reading every thread themselves
Cross-team production support
Pick up ad hoc marketing production requests (design briefs, YouTube channel merchandising, banner requests) so they don't fall to senior team members
Flag blockers and surface feedback across content, growth, and product marketing to keep the team aligned
Workflow automation
Identify manual, repeatable tasks in the production pipeline and build lightweight automations or Claude skills for them
WHAT GOOD LOOKS LIKE
Publishing runs on schedule with few follow-ups needed
Authors and stakeholders get consistent, visible accountability through one shared channel
Distribution reach (impressions, upvotes, referred traffic) grows month over month against a shared baseline
WHAT WE'RE LOOKING FOR
Must have:
Strong written English and good judgment on public tone, since comment moderation and response require calling the right register in public
Comfortable working across functions without a fixed lane; this role touches content and growth in the same week
Comfortable navigating LinkedIn, X, Reddit, and YouTube Studio day to day
Has used AI and can demonstrate a workflow or application you’ve built
Nice to have:
Familiarity with Reddit/Hacker News community norms
Basic Notion/Linear fluency
Some comfort with no-code or lightweight scripting for internal tooling
No marketing strategy experience required, this is an entry-level role, well suited to an early-career marketer, a career switcher, or someone returning to work after a break.
SALARY AND BENEFITS
Office: Our brand new 10,000 sq. ft office is in the AI hub of Kings Cross, London. We have generous catering and regular social events such as team lunches, drinks, and more. We require all staff to be in our London HQ at least 3 days a week on our anchor days of Monday, Tuesday, and Thursday.
Salary: We offer a competitive salary based on experience and skills, benchmarked against industry standards and appropriate for an entry-level/apprenticeship position.

Final conversation with the marketing team
We encourage you to apply even if you don't meet every requirement. We care about talent, trajectory, and mindset, not just checkboxes.
We care deeply about the warm, inclusive environment we’re building at Tessl and we value diversity – we welcome applications from those typically underrepresented in tech. If you like the sound of this role but are not totally sure whether you’re the right person, do apply anyway!
