*If you are interested in this role, please apply directly via Djinni.
 

About the Role 
We're hiring our first AI Automation Specialist to lead applied AI across the company. This is a hands-on, cross-functional role: you'll sit with teams in Sales, Operations, Finance, and beyond, find the work that drains their time, and replace it with reliable AI-powered workflows. 

This is an implementation and ownership role, not a research one. You won't be training models or doing data science — you'll be composing existing AI tools, APIs, and no-code/low-code platforms into workflows that run in production, and you'll own them once they're live. If you like turning "we waste ten hours a week on this" into something that just works, this is your role. 
 

We’re looking for someone long-term, at least a year commitment. 

Responsibilities 

• Assess each department's workflows to identify high-value opportunities for AI automation (repetitive, multi-step, or judgment-assisted tasks). 
   
• Design and prototype agentic workflows (multi-step AI agents, tool integrations, approval/human-in-the-loop checkpoints) tailored to each department's needs. 
   
• Act as the internal point of contact between departments for ai transformation 
   
• Select and configure the right tools/platforms (e.g., Claude Cowork, MCP connectors) for each use case 
   
• Monitor deployed workflows for performance, drift, and failure modes, and iterate or retire workflows that underperform. 
   
• Track adoption metrics per department and report progress to leadership. 

Requirements 

• Experience in process automation with AI, systems integration, business-process optimization, or a closely related field. 
• Ability to communicate across both technical and non-technical teams. 
• Strong process-mapping and business-analysis skills — the ability to translate a business problem into a working, monitored automation. 
• An ownership mindset: you care about reliability, edge cases, and proving impact — not just shipping a demo. 
• Hands-on experience with workflow automation platforms — any of n8n, Make, Zapier, or Power Automate. 
• Comfort with APIs, webhooks, and JSON, plus the ability to write light scripts (Python or JavaScript) when a no-code tool hits its ceiling. 
• English level: Upper-Intermediate. 
   

*This is an applied automation role. Machine learning, model training, algorithm development, and data science are not part of this position. 

What We Offer 

• Real ownership from day one — you'll define how AI works across the whole company, not just execute someone else's plan. 
• Direct impact and visibility — your work touches every department and is reported to leadership. 
• Modern tooling and autonomy to choose the right platforms for the job. 
• Competitive salary  
• Health insurance + Well-being program (250 USD/year) 
• Paid time off + extra Christmas week 
• PE accounting support 
• Supportive, collaborative team 
• Engaging Team events 

PwC is a global network of more than 370,000 professionals in 149 countries that turns challenges into opportunities. We create innovative solutions in audit, consulting, tax and technology, combining knowledge from all over the world.

About
 

We're a Y Combinator-backed startup building the AI infrastructure layer for the IT services industry: the platform IT providers use to deliver governed AI to the small businesses they manage, and to build and run AI agents for them on the same rails.
 

It's a genuine blue-ocean space, no incumbent has built this yet - while demand is already strong and validated: our first ad and outbound experiments are both booking calls with IT business owners at exceptional economics, and small businesses are paying thousands of dollars per month for AI delivered this way today.
 

The founder previously built an AI coding platform to 2M+ users. You'd join as the founding go-to-market hire at the exact moment the category is forming.
 

What you'll do
 

You'll be the first GTM hire, working directly with the founder and owning the pipeline. The role has two tightly connected halves:
 

1. Pipeline generation - fill the calendar

Run outbound lead generation: build target lists of IT service providers, write and send sequences (email, LinkedIn), book qualified calls - we have a working outbound motion already booking calls, and you'll take it over and scale it

Own our paid ads across Reddit, Meta/Facebook, and new channels: creatives, copy, targeting, budgets, and cost-per-call optimization (we already have working ad motions to build on)

Build nurture campaigns and lead magnets: guides, checklists, email sequences that warm up leads who aren't ready to buy yet

Represent us at industry conferences and events across the US, EU, and Australia: work the floor, book meetings, gather intelligence on what the market is asking for

Test go-to-market motions systematically: different messages, offers, channels, and audiences - measure cost per call and conversion, kill what doesn't work, scale what does

2. AI GTM enablement - the discovery half

Investigate how our customers can sell and upsell AI to their own clients: join their sales conversations, interview them, and study what works

Build the enablement library our customers use to sell: pitch decks, one-pagers, ROI calculators, and campaign kits they can send directly to their clients

Develop agent use-case templates by industry (e.g., what an AI agent does for a dental office, a law firm, a construction company) that customers can present to their clients

Turn what you learn into repeatable sales playbooks: which pitches convert, which industries pull hardest, what objections come up and how to answer them

Feed everything back to the founder and product: you're the closest person to the market, and what you discover shapes what we build

This is not a script-following SDR seat. It's a 0-to-1 GTM role: half of the job is generating pipeline, the other half is building the playbook for how an entirely new category gets sold - twice (by us to IT providers, and by IT providers to their clients).
 

What we're looking for
 

Who you are

Strong empathy, and genuine willingness to learn an unsexy vertical: our buyers are IT service providers - small business owners with real problems, tight margins, and deep skepticism of vendors. You find people like this interesting rather than boring, you'd happily spend hours understanding how their business actually works, and they can tell you respect them

4+ years in outbound sales, BDR/SDR, growth, or demand generation for B2B

You've generated pipeline yourself. You've personally built lists, written sequences, run campaigns, and booked meetings - not just managed an agency or a tool

Hands-on experience running paid ads (Meta/Facebook, Reddit, LinkedIn, or Google): you've owned budgets, written creatives, and optimized for cost per lead

Excellent written English - your outreach, ads, and enablement materials go to US business owners, and the writing has to land

Experienced with US culture and communication norms - you've worked with US customers or teams, you know how American business owners talk, what tone lands in their inbox, and how to run a call that feels natural to them, not translated

Confident on calls with US customers: discovery conversations, note-taking, pattern-spotting

Willing and able to travel internationally to industry conferences and events in the US, EU, and Australia - working the floor, booking meetings, and representing us in person is a core part of the role, not an occasional perk

Discovery-driven: you dig into why something worked, interview customers, synthesize patterns, and turn what you learn into playbooks and enablement material others can use

Daily user of AI tools (ChatGPT, Claude, or similar) to research, write, and build campaigns faster - you'll be selling AI, so you need to live in it

Comfortable owning everything alone: you don't need a manager, a playbook, or a team to be effective - you design the experiment, run it, measure it, and report what happened

You genuinely love go-to-market experimentation and reasoning from first principles: there is no incumbent playbook for this category, and that excites you rather than scares you. You form hypotheses about why a buyer should care, design the cheapest test that could prove you wrong, run it, measure it, and write the playbook as you go

Nice to have

Startup experience - you've worked at an early-stage company (or founded/run your own project) and know what building under real constraints feels like
Experience selling B2B SaaS, or familiarity with the IT services / managed services industry
Experience with field marketing or conferences: booths, event outreach, follow-up motions
Fluency with modern GTM tooling: CRM (HubSpot or similar), outbound tools (Apollo, Instantly, Clay, or similar), landing page builders
Content creation skills: landing pages, lead magnets, short video, or design basics

What we offer

Meaningful equity - founding-team ownership, not a token grant
Competitive salary (discussed openly at the first call, benchmarked for senior specialists) plus performance bonus tied to booked qualified calls and pipeline - typically adding 20-40% on top of base at target, reviewed as the motion scales
Remote work, with core overlap hours with customers and the founder
International travel - fully covered trips to industry conferences and customer visits in the US, EU, and Australia
Direct work with the founder - no layers, you shape the go-to-market from day one
A concrete, revenue-backed problem: working ad motions, validated demand, and a category forming in real time
Hardware/co-working budget and paid time off

Hiring process

Intro call (30 min) - mutual fit, product walkthrough, comp expectations
GTM deep dive (60 min) - you walk us through a campaign or pipeline you've personally built and run, your choice: the numbers, what worked, what didn't, what you'd redo
1-month paid trial - full-time, fully compensated real work: you run pipeline and GTM experiments with the founder. This is a mutual trial: you evaluate us as much as we evaluate you. On conversion to the permanent founding role, equity vesting is backdated to your start date.

Total process time: under two weeks.

Engagement: Contract (full-time) · Remote Stack: React (primary) · Python (backend) · existing Vue · AWS DynamoDB · in-house UI toolkit

About the role

You’ll work on the internal compute-platform web application of a US robotics / autonomous company — the system that runs safety simulations and large-scale compute workloads (training, batch inference, MapReduce-style jobs) across a cluster of roughly 50,000–100,000 nodes.

The app is the task-management UI where engineers submit and track jobs: job status and queue time, debugging, and understanding jobs modeled as DAGs (directed acyclic graphs) — which steps ran, which failed, what resources were consumed, why a job is slow, and how to optimize it (e.g. GPU utilization, switching between CPU/GPU nodes).

The application is ~10 years old; its first version was in Vue, and a React migration began ~18 months ago (the team is now building the next major version). The approach is incremental: a host shell with key pages implemented in React, iframing much of the older Vue app. Today it’s ~90% frontend — a React app calling many existing services — and will grow its own dedicated Python backend over time, moving toward roughly two-thirds frontend / one-third backend in steady state.

This is a senior, autonomous role. Design/product support is limited to UI polish, so you’ll exercise product judgment yourself — walking through user flows as a user, and asking clarifying questions when a ticket isn’t well-defined.

What you’ll do

• Build and rework user interfaces in React; migrate the remaining Vue components to React and build new React components.
• Reuse the team’s shared component library / in-house UI toolkit.
• Grow a lightweight Python backend — application-level joins, light workflow/processing, a DynamoDB store for things like user preferences — while the app continues to call many existing services.
• Visualize complex job/DAG data clearly: status, failures, resource usage, and performance.
• Talk to users, clarify ambiguous requirements, and ship features end to end.

Must-have

• Strong, hands-on React — modern hooks, component architecture, state management, performance.
• Solid Python for backend development.
• General database experience.
• A product mindset: questions whether a ticket is well-defined, pushes back constructively, drives clarity instead of waiting for prescriptive specs.
• Ability to operate at a senior level — autonomous, user-facing, proactive, comfortable owning features end to end.

Nice-to-have

• Ability to read and understand Vue (to migrate existing components).
• Experience with complex data visualization / dashboards, ideally graph/DAG rendering.
• WebGL — only for advanced graph visualization; genuinely optional (fine without it).
• Experience with a shared component library / design system.
• Experience with internal developer platforms, compute, or infrastructure tooling.

What success looks like

In the first months you’ll take ownership of meaningful parts of the app — migrating Vue screens to React, shipping UI improvements users notice, and starting to shape the Python backend — while reducing the hand-holding needed to move a feature from idea to production.
