ABOUT THE COMPANY

Our client is a well-funded AI product company building a “second brain” for senior HR leaders and their teams. Its platform combines AI, people analytics, and a professional network used by thousands of C-level executives.

We're looking for a Fullstack Product Engineer who wants to:

• Own features end-to-end, from deeply understanding the customer problem to shipping the feature and driving its usage & adoption.
• Work across the entire stack (React, TypeScript, NestJS, PostgreSQL).
• Ship fast & high quality;you believe speed vs. quality is a false choice, and in fact you can increase both in lockstep.
• Work directly with customers: from hopping on calls, to debugging their problems, and then iterating based on real feedback
• Craft positive-sum engineering practices that increase velocity.
• Become one of the first 3 engineers in the AI & Analytics pod

This is only an in-person role (4-5 days/week) in NYC. The company has a beautiful office in a 1,000+ ft skyscraper in the heart of Hudson Yards, New York.

TECH STACK

• Frontend: React, TypeScript, Vite
• Backend: NestJS, TypeScript
• Data: PostgreSQL, Redis
• Infrastructure: AWS, GitHub Actions
• Observability: Sentry, New Relic
• AI Dev Tools: Cursor, Claude Code (or similar)

Nice to have: SQL proficiency and experience working with data warehouses (the team use Snowflake for analytics).

CANDIDATE CRITERIA

• You have 2-6 years building and shipping product.You've worked on real products with real users. You've felt the pain of production issues and learned from them.
• You're strong across the stack.You can build a React component, write a backend service, and debug a database query. You might be stronger in one area, but you're not helpless in any of them.
• You genuinely enjoy customer interaction. You've been on customer calls before and found them valuable, not painful. You understand that great products come from deeply understanding user problems.
• Strong SQL knowledge is a plus.We build querying engines on top of Snowflake data—if you're comfortable writing and optimizing complex queries, that's a big advantage.
• You're AI-native and AI-augmented.Cursor, Claude Code, AI-assisted reviews—these have fundamentally changed how you work. You're constantly experimenting with new AI tools and have opinions on what's worth adopting. If you're still coding the way you did in 2022, this isn't the right fit.
• You have an owner's mindset. Self-driven, resourceful, ready to build and be in the trenches. You don't need to be managed; you need to be pointed at problems.
• You've worked in high-intensity environments.Startups, high-growth teams, or any context where speed and quality both mattered.
• You're a positive influence on every team you've been on. Low ego, high standards

WHAT YOU'LL DO

• Ship features end-to-end from problem understanding to production, across frontend and backend
• Talk to customers regularly: join calls, gather feedback, and translate their problems into solutions
• Write code that lasts with tests, edge case handling, and clear documentation
• Review code thoughtfully and hold the bar on quality for the team
• Debug production issues and make sure they don't happen again
• Help cultivate engineering culture as one of the founding engineers of this pod

We are looking for a Senior Media Buyer to own paid acquisition in the financial publishing vertical on Meta and Google. We work with the top partners in the space, so you will have strong offers to run. Offer access is not the hard part. Performance is. What we need is someone who can take a proven offer, find the angle, and make it profitable at scale.
 

This is not a role for someone who maintains campaigns that already work. It is a full ownership seat for a buyer who can walk into a cold offer with no creative history, form a view on the angle within a day, get it live, kill what is not working fast, and scale what is. You will be judged on profit, not on impressions, click-through rates, or how busy the account looks.

The work sits in financial publishing, but we are not hiring someone who has only ever bought in one place. Buyers who spent an entire career optimizing inside a single niche arrive with one playbook and no
second move when it stops working. Buyers who have run financial, health, auto, home, or other direct response markets and stayed profitable across them bring range, and range is what holds up when a
channel shifts or an angle burns out.

This is a hands-on seat and it stays that way. You are in the accounts yourself, at pace, with serious budget behind you. What comes with that is full ownership: the strategy is yours to set, the decisions are
yours to make, and the results are visible to everyone.

WHAT YOU WILL OWN
Offer launch and profitable scale:
● Take financial publishing offers from cold launch to profitable scale on Meta and Google
● Own the full campaign lifecycle: research, angle selection, launch, optimization, scaling, and the decision to cut
● Own the profit and loss on every campaign you run. Payout, cost per acquisition, margin, and volume are your numbers to defend
● Decide which channel fits which offer rather than pushing everything through the same playbook
● Prioritize ruthlessly across the offers available to you. Know which ones deserve budget this week and which do not
● Scale winners aggressively without letting performance collapse under the extra spend
● Build repeatable launch playbooks so a new offer goes live in days, not weeks

Creative direction and angle development:
● Own the angle. You decide what the hook is, who it speaks to, and why it will convert before
anything gets designed
● Brief designers, copywriters, and video editors with enough specificity that the first round is testable rather than decorative
● Build and maintain a creative testing pipeline with the volume and cadence the platforms demand
● Own advertorials, pre-landers, and landing page angles alongside the ad creative, and test the full path rather than the ad in isolation
● Adapt the approach to the channel. Interruption traffic and intent traffic need different angles, different funnels, and different proof
● Run competitive and market research continuously. Know what is running, what is fatiguing, and what is about to work
● Use AI tools to increase creative throughput and research speed where they genuinely help, and know where they do not

Testing discipline and budget control:
● Design test structures that produce clean signal: what is being tested, at what budget, and what result triggers which decision
● Set explicit kill rules and scale rules in advance so decisions are made on data rather than on hope
● Manage daily and monthly budgets against targets, and flag early when spend is not going to return
● Keep a clear record of what has been tested and what it produced, so the same losing angle is not relaunched twice
● Balance exploration and exploitation deliberately. Protect budget for new offers and new angles even while scaling a winner

Tracking, data, and attribution:
● Own the tracking setup end to end: trackers, server to server postbacks, conversion APIs, pixels, and parameter hygiene
● Validate that the numbers are real before scaling on them, and debug attribution gaps yourself rather than escalating them
● Work with analytics on reporting that shows profitability by offer, angle, creative, and placement
● Reconcile platform data against network and advertiser data, and chase discrepancies until they are explained
● Use post-click and post-conversion data to inform buying decisions, not just front end metrics

Account infrastructure and compliance:
● Own account structure, ad account health, and the operational setup that keeps spend running without interruption
● Keep creatives and funnels inside Meta and Google policy. We build for longevity, not for a week of spend before a ban
● Manage relationships with platform reps and vendors, and use them to unlock scale and resolve issues fast
● Work with our partners on payouts, caps, creative approvals, and early access to new offers
● Maintain documentation on setups, integrations, and process so nothing sits only in your head

Playbooks and standards:
● Turn what works into documented playbooks: launch structures, test frameworks, angle libraries, and creative briefs
● Set the standard for how buying is done here through your own results
● Report on a clear cadence: what is spending, what is working, what gets cut this week, and what needs a decision
● Share what you learn with the creative and analytics teams so wins do not stay locked inside your accounts

WHAT WE ARE LOOKING FOR
Must-have:
● 5 or more years of hands-on media buying with direct ownership of spend and profitability, not
agency reporting or campaign assistance
● Big-budget experience. At least 100,000 dollars a month in ad spend that you personally managed, sustained over time rather than in one spike. Below that level this is not the right role
● Financial publishing experience is what we are looking for first. Health direct response is the closest adjacent background
● If not financial publishing, then a track record across at least three distinct verticals, with auto and home a strong plus. A career spent inside a single niche is a mismatch here, and gambling-only backgrounds in particular tend to be too narrow
● Deep Meta buying expertise: account structure, testing frameworks, creative volume, scaling mechanics, and account health at high daily spend
● Hands-on Google buying experience across at least one of Search, Demand Gen, YouTube, or Performance Max, with a real view on how buying there differs from Meta
● Proven ability to take an offer from zero to profitable scale, with specific numbers you can walk through
● Creative and angle ownership. You direct the creative and the funnel rather than waiting for assets to be handed to you
● Tracking fluency: trackers, server to server postbacks, conversion APIs, and the ability to debug attribution yourself
● Comfortable being measured on profit and comfortable saying when something is not working
● Self-directed. You can run a full portfolio without a large support structure around you
● Excellent English, written and verbal (C1 or above)

Nice to have:
● Native buying experience on the major networks
● Financial publishing, newsletter, or subscription direct response background
● Auto and home verticals, including insurance and home services lead generation
● Subscriber acquisition and list building economics, buying against lifetime value rather than front end conversion alone
● Familiarity with the funnel formats this vertical runs on: advertorials, long form sales pages, VSLs, and lead magnets
● Fluency with AI tools for creative production, research, and analysis

WHO FITS THIS ROLE
You are a buyer who has scaled offers profitably with your own money on the line, or close enough to it that it felt that way. You can walk through the numbers on your best campaigns and your worst ones
without reaching for excuses. You know the difference between a campaign that worked and a campaign that happened to run during a good week. 

You have worked across several verticals and you treat that as your advantage rather than a gap. You have been the new person in an unfamiliar market before, and you know how you get up to speed: the research, the angles you borrow, the assumptions you test first. Buyers who have only ever run one niche tend to have one playbook. You have several, and you know which one to reach for. You think in angles before you think in settings. You know that creative and offer selection decide most of the outcome and that account optimization only moves the last stretch. 

You brief creative properly, you
test at volume, and you do not fall in love with an ad that is losing money. You move fast and you decide fast. You do not need a full picture before you act, and you do not sit on a losing test hoping it turns. You set your kill rules in advance and you follow them.

You work independently and you want to stay in the accounts. You are used to owning a portfolio without a machine of specialists behind you, and you know how to get what you need from the people around
you. This is a senior buyer seat, and going deeper on the channels rather than away from them is the point.

Our client is building a digital twin engine that simulates enterprise IT environments (cloud, SaaS, identity, endpoints, networks, security products) with high fidelity, then runs attacks from agentic red teams against them to capture realistic telemetry for AI security training and evaluation.

This is a zero-to-one build — you'll define the architecture and technical direction from scratch.
 

Who we're looking for

A hybrid of offensive security expert and production software engineer — someone who thinks like an attacker and can turn that into a reliable, scalable system. Not a pure pentester, not a pure backend engineer.
 

Scope of Work

• Own the architecture and hands-on development of the digital twin engine.
• Build high-fidelity simulations of company stacks — users, networks, cloud, SaaS, identity, endpoints, security products.
• Run attacks from agentic red teams and capture realistic telemetry.
• Adapt environments to customer stacks while protecting privacy, isolation, and authorization boundaries.
• Lead the technical roadmap and engineering standards across contributors.
• Keep the engine reproducible, reliable, scalable, and easy to extend.
   

Requirements

• Deep offensive/defensive security knowledge, including how security products (EDR/XDR/SIEM) work internally.
• Cloud security experience (AWS/Azure/GCP) and familiarity with anti-forensics techniques.
• Ability to judge whether a scenario and its telemetry are realistic, too easy, or ambiguous.
• Strong software engineering skills — proven experience shipping and operating production systems.
• Experience building cyber ranges, digital twins, security labs, or large-scale simulated environments.
• Strong knowledge of security telemetry and data pipelines (cloud, SaaS, identity, endpoints, networks).
• Comfortable leading ambiguous, zero-to-one development under uncertainty.
• Strong project planning, technical coordination, and code review skills.
   

Nice to have: AI agents/evals experience (guardrails, reproducibility, human review); conference talks or CTF/red team community involvement; background at BAS companies (Pentera, SafeBreach, Cymulate) or cyber range platforms (CybExer, SimSpace).
