Position Overview

NYC Glass & Window Repair is looking for a motivated, organized, and results-driven Sales Representative to manage incoming leads, communicate with residential and commercial customers, prepare estimates, follow up on opportunities, and convert inquiries into booked projects.

The ideal candidate is comfortable speaking with customers, understands consultative sales, follows up consistently, and takes ownership of every lead from the initial inquiry through closing and handoff to the operations team.

Experience in windows, doors, glass, construction, home improvement, or building services is highly preferred but not required if the candidate is willing and able to learn the technical aspects of our services.

Key Responsibilities

• Respond quickly to new leads received by phone, email, website, text, and other channels.
• Speak with customers to understand the problem, project scope, budget, timeline, and expectations.
• Review customer photos, videos, measurements, drawings, and project documentation.
• Determine whether the project can be quoted remotely or requires an on-site assessment.
• Schedule site visits and coordinate with estimators when necessary.
• Prepare and send professional estimates and proposals.
• Explain proposed solutions, materials, hardware, glass options, lead times, warranties, and pricing to customers.
• Follow up consistently on all open estimates and sales opportunities.
• Negotiate professionally while protecting company margins.
• Convert qualified leads into signed/approved projects and collect required deposits.
• Upsell and cross-sell appropriate services when they genuinely benefit the customer.
• Maintain accurate customer information, notes, estimates, follow-up dates, and sales stages in the CRM system.
• Re-engage previous customers and older leads when appropriate.
• Coordinate sold projects with scheduling, purchasing, project management, and installation teams.
• Maintain communication with customers until the project has been properly handed off.
• Develop long-term relationships with property managers, general contractors, architects, designers, building owners, and repeat customers.
• Meet individual sales, revenue, conversion-rate, and follow-up KPIs.

Services the Sales Representative Will Sell

The representative will be trained to sell services including window repair and replacement, insulated glass (IGU) replacement, commercial and residential glass replacement, door repair and installation, storefront glass and aluminum systems, shower enclosures, custom mirrors, glass partitions, railings, historical window restoration, window screens, smart glass and window film, and specialty glazing projects.

Sales Process

The Sales Representative is expected to take ownership of the sales pipeline:

New Lead → Qualification → Site Visit/Estimate → Proposal → Follow-Up → Negotiation → Closing → Deposit → Operations Handoff

A lead should never be left without a clearly documented next action or follow-up date.

Requirements

The ideal candidate should have excellent verbal and written English, strong communication and negotiation skills, and the confidence to speak with both homeowners and commercial clients.

The candidate must be highly organized, comfortable working with CRM systems, able to manage multiple opportunities simultaneously, and persistent with follow-ups without being overly aggressive.

Basic mathematical skills are required for measurements, quantities, pricing, percentages, and margins. The candidate must also be comfortable learning technical terminology related to glass, windows, doors, hardware, framing systems, and construction.

Preferred Experience

Previous experience in construction sales, window and door sales, glass and glazing, home improvement, building materials, property services, or B2B sales is a strong advantage.

Experience dealing with property managers, general contractors, architects, designers, management companies, and commercial clients is also highly desirable.

Key Performance Indicators (KPIs)

Performance should be evaluated primarily on sales revenue, gross profit/margin, lead-to-sale conversion rate, estimate-to-sale conversion rate, speed of response to new leads, follow-up completion rate, average project value, CRM accuracy, and repeat/referral business.

What We Are Looking For

We want someone who is sales-driven but not pushy. The goal is not simply to give customers a price—it is to understand what they need, recommend the correct solution, explain why it is the right solution, build trust, and close the project.

The right candidate should think:

“Every qualified lead needs a clear next step until the customer buys, declines, or the opportunity is formally closed.”

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. We need someone who can take a proven offer, find the angle, and make it profitable at scale.

You 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. The strategy is yours to set, the decisions are yours to make, and you are judged on profit — not impressions, click-through rates, or how busy the account looks.

This is a hands-on senior individual contributor seat with serious budget behind it, and it stays that way.

Key Responsibilities

• 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 P&L on every campaign you run — payout, CPA, margin, and volume are your numbers to defend
• Own the angle: decide the hook, 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
• Run a creative testing pipeline at the volume and cadence the platforms demand, including advertorials, pre-landers, and landing pages — test the full path, not the ad in isolation
• Design clean test structures with kill rules and scale rules set in advance, and manage budgets against targets
• Own tracking end to end: trackers, server-to-server postbacks, conversion APIs, pixels, and parameter hygiene — and debug attribution yourself
• Validate that the numbers are real before scaling on them, and reconcile platform data against network and advertiser data
• Own account structure, ad account health, and compliance with Meta and Google policy — we build for longevity, not a week of spend before a ban
• Run competitive and market research continuously, and use AI tools where they genuinely increase creative and research throughput

• Turn what works into documented playbooks and report on a clear cadence: what is spending, what is working, what gets cut

   

Requirements

Must Have

• 5+ 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/month in ad spend you personally managed, sustained over time rather than in one spike
• Financial publishing experience preferred; health direct response is the closest adjacent background
• If not financial publishing, a track record across at least three distinct verticals (auto and home a strong plus) — a career inside a single niche is a mismatch here
• Deep Meta expertise: account structure, testing frameworks, creative volume, scaling mechanics, and account health at high daily spend
• Hands-on Google experience in at least one of Search, Demand Gen, YouTube, or Performance Max, with a real view on how it 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
• Tracking fluency: trackers, server-to-server postbacks, conversion APIs, and the ability to debug attribution yourself
• Self-directed: able to 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
• 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, not front-end conversion alone
• Familiarity with advertorials, long-form sales pages, VSLs, and lead magnets
• Fluency with AI tools for creative production, research, and analysis

Who We're Looking For

We're looking for someone who:

• Has scaled offers profitably with real budget on the line, and can walk through the numbers on their best and worst campaigns without reaching for excuses
• Treats multi-vertical range as an advantage and has a method for getting up to speed in an unfamiliar market
• Thinks in angles before settings — creative and offer selection decide most of the outcome
• Moves fast, decides fast, sets kill rules in advance and follows them
• Works independently and wants to stay in the accounts, going deeper on the channels rather than away from them

• Is comfortable being measured on profit, and comfortable saying when something is not working

We look forward to meeting you!

About us

Benrey is a digital team working with international markets — SEO, PPC, link building, in-app, DSP, plus web and app development. We run large multi-domain, multi-language platforms in highly competitive niches, where manual optimisation simply doesn't scale and anything repeatable has to be automated.

Who we're looking for

A technical SEO who is equally comfortable in the console, in server logs and in code. This is not a "fix meta tags from a checklist" role. The value here is building systems that hold optimisation across hundreds of thousands of pages and keep running without manual work.

We need someone who can identify what hurts most and fix it without a step-by-step spec.

What you'll do

— Technical audits of large sites. Crawling, indexing, rendering, crawl budget. Finding bottlenecks in complex structures where the problem isn't visible from any interface.

— Rendering and migrations. Diagnosing CSR / SSR / partial SSR, planning and running migrations, verifying what the bot actually receives rather than what the browser shows. Working with hydration, prerendering and caching at scale.

— SEO A/B testing on programmatic pages. Hypothesis, splitting pages into groups, staged rollout, verifying the deployed state against the intended one, correlation analysis, filtering out seasonality and algorithm updates. Knowing the difference between a real effect and noise, and not drawing conclusions from two weeks of data.

— Server log analysis. How bots actually move through the site, where crawl budget leaks, which templates never reach the index, what changed after a release.

— Building your own tooling in Python or TypeScript. Bulk checks, change monitoring, structured data validation, internal linking, automated audits, dashboards. Systems that run continuously, not one-off scripts.

— LLMs in production, not in a chat window. Pipelines for content generation and validation, page classification, anomaly detection, working through APIs (Claude, Gemini, OpenAI).

— Structured data, canonicals, robots directives, XML sitemaps — handled at template and auto-generation level, not page by page.

— Core Web Vitals and performance. Diagnosis, writing clear tickets for developers, verifying the result shipped.

— Analytics and reporting. Making changes in crawling, indexation and visibility (including AI overviews) visible as numbers, not as gut feeling.

— Working with engineering. Writing technical requirements developers can act on, arguing priority, seeing tickets through to release.

— Documenting the systems you build so they keep working without you.
 

What we expect

• Solid technical SEO experience on large projects — tens of thousands of URLs and up, multi-language or multi-domain
• Hands-on experience with an SSR migration — a project you owned or led the SEO side of, not theory
• Experience with partial SSR at scale: which parts of the page render server-side, which client-side, and what actually makes it into the index
• Experience running SEO A/B tests on programmatic pages — segmented rollout, verification, honest analysis of results
• Python or TypeScript at the level of "I write working tools myself", not "I took a course"
• Strong grasp of HTML, CSS, JS and how rendering strategy affects indexing, speed and accessibility
• Practical work with logs and APIs — GSC API, crawlers, databases
• Experience with LLM APIs or automation built on top of them
• Autonomy and confidence in your own decisions: not just finding the problem, but driving it to a fix through other teams

Nice to have

• iGaming, programmatic SEO website/SAAS or large-scale e-commerce
• BigQuery, ClickHouse, working with large datasets
• Playwright, headless crawling
• Statistical literacy when evaluating test results
• Mentoring or reviewing other people's technical work

What we offer

• Remote work, competitive salary
• Direct work with the technical team — no layer of managers between you and the task

• Freedom to choose the stack and the tools you build

   

How to apply

Tell us two things in your cover note:

1. A tool you built yourself and the problem it solved.
2. A case where logs or raw data revealed a problem that no crawler or GSC report showed.

Applications without answers to these won't be reviewed.
