Single-owner tasks
You own your work end to end. Nothing gets handed off into a void.
AI-native by default
The newest models from day one, pointed at real users. That is the baseline here, not a perk we ration.
Learn at speed
You will cover more ground in a year here than most people do in three.
Real distribution
Infinity Learn reaches millions of students a month, so nothing you build sits in a drawer.
Opinions lose to evidence
Research and data sit next to product here. We run focus groups continuously and test in multiple variants, then follow what the students actually did.
Built by people who have shipped at scale.
We have built learning products used across India, at Unacademy, PhysicsWallah, Shopify, Atlassian, Zupee and NID.

- Add regional-language support in game UI (Hindi, Odia, regional scripts)
Required
- Strong JavaScript fundamentals: clean, performant JS
- Hands-on with Phaser or similar 2D frameworks (Pixi.js, Kaboom.js): you've shipped something
- Game composition sense: scenes, states, loops, feedback, feel
- AI-native workflow for code, assets and iteration
- Genuine love for games: you play them and have opinions
Nice to have
- Early-childhood (three to six) or non-tech-native audience experience
- Asset pipelines: sprite sheets, texture atlases, audio compression for web
- Web animation (GSAP, CSS, canvas) beyond game engines
- Government, civic-tech or public-sector project experience
Graphic & Motion Designer
Designs the visual world of I3W: game art, UI, brand and motion, in an AI-native pipeline. Freshers welcome.
What you'll do
- Create graphics: characters, illustrations and UI across games, learning apps and tools, plus brand collateral and decks
- Own logo and brand work: applications and identity consistency across everything I3W ships
- Bring graphics to motion: sprite sheets, character cycles, UI motion, feedback animations (Lottie / frame-based)
- Produce motion-graphic videos: explainers, promos and social content
- Generate and refine assets in an AI-native pipeline: prompt, iterate, then polish by hand
- Pick up varied tasks as priorities shift: no two weeks look the same

User Research Head
Owns user research. We run focus groups continuously and what comes out of them drives the roadmap, so this is not research that gets filed away.
What you'll do
- Design and run focus groups with students on a regular cadence, the core research engine here
- Own the research practice: methods, cadence, and a repository the team actually uses
- Run the full qualitative mix alongside groups: interviews, usability sessions, diary studies
- Synthesise findings into clear recommendations, and argue for them in the room
- Work with the Data Analyst so what students say and what they do get read together
- Close the loop: track what changed because of research, and what did not
Required
- 6+ years in user research, including time leading or building a function
- Strong focus group craft: recruiting, moderating, and reading a room
- Broad qualitative toolkit: interviews, contextual inquiry, usability testing
- Comfort with quantitative inputs, both surveys and product analytics
- Fluency in Hindi and English, so you run sessions in the language students speak
- Influence without authority: your work changes what gets built
Nice to have
- EdTech, exam-prep or K-12 research background
- Experience researching teenagers, and parents as co-decision-makers
- Research on AI or conversational products
- Having built a research repository others genuinely used
Data Analyst
Owns testing and metrics. We run A/B/C/D variants rather than simple splits, and every result gets read next to what research hears from students.
What you'll do
- Design and run multi-variant experiments (A/B/C/D): sizing, splits, duration, and a clear call at the end
- Define and track the metrics that matter, and keep everyone honest about what they mean
- Build the event tracking plan with engineering so data is trustworthy at the source
- Work alongside user research, pairing test results with focus group findings to explain the why
- Analyse funnels, retention and cohort behaviour across student segments
- Build dashboards the team reads without asking, and go deeper when they do
Required
- 2+ years in product or business analytics
- Hands-on experimentation experience: you have designed and called real tests
- Strong SQL: you can answer a messy question without hand-holding
- Python or R for analysis
- Product analytics tools (PostHog, Mixpanel, Amplitude, GA4) and event instrumentation
- Statistical literacy: significance, sample size, and the discipline not to overclaim
Nice to have
- Running many concurrent variants, not just simple A/B splits
- Having worked directly with a user research team
- EdTech or subscription consumer products
- Data pipelines and warehousing (BigQuery, dbt, Airflow)
User Research Ops
Keeps our research cohorts alive and growing. Focus groups only work if the right students keep turning up, so someone has to stay in touch and keep finding new cohorts.
What you'll do
- Own day-to-day coordination with our student cohorts, keeping them warm and responsive
- Keep cohorts active: follow-ups, reminders, incentives, and simply making participation easy
- Continuously scout and recruit new cohorts so the pool keeps growing and stays representative
- Screen participants and match them to the right study
- Schedule and run logistics for focus groups and sessions, including field visits
- Capture notes and transcripts, and keep the research repository current
Required
- 0 to 2 years of experience, internships count
- Seriously organised: you track a lot of people and nothing slips
- Genuinely good with people, so students reply to you and turn up
- Comfortable cold-contacting strangers and building a group from nothing
- Clear written English and comfortable conversational Hindi
- Curious about how students study and why they drop off
Nice to have
- Community management or student outreach experience
- Any exposure to user research, surveys or fieldwork
- Familiarity with NEET or JEE prep, bonus if you have lived it
- Comfort with AI tools for transcription and note-taking
