About us

GigRadar is the market leader in our vertical: AI-powered lead generation on Upwork for agencies and freelancers. We remove the need for in-house bidding teams and multiply agencies' marketing efficiency.
 

A quick picture of who you'd be joining:

• Infrastructure trusted by 3,000+ Upwork agencies worldwide.
• 4.7/5 "Excellent" on Trustpilot, with 91% five-star reviews.
• 30K+ LinkedIn audience and a strong founder brand.
• Backed by a leading SalesTech/MarTech player (on our board)
• A product line of AI agents: Sardor AI (auto-bidder — finds relevant jobs, writes personalized cover letters, and submits within 15 minutes), Laziza AI (AI SDR — runs conversations, handles objections, books meetings), Upwork CRM, Upwork Analytics, and GigRadar Inbound.

We're not a day-one startup, and we're not a slow enterprise. We have a proven business model, a mature product, a fast-growing AI lineup, and clear leadership in our niche - confident operators growing fast.

And most importantly for this role: strong channels are already running.

• SEO — a dialed-in channel built entirely on AI agents.
• Email + LinkedIn outreach — its own team.
• Partner / referral network — its own team.

You're not here to patch holes but you're here to build a new amplifier vertical on top of a working machine. You won't have to prove the business works; it's been alive for years. You'll get to build your own growth engine and scale it. On top of that, we have a large library of ready material (case studies with numbers, Upwork Reports, community content, reviews) you can turn into powerful marketing.

The mission

Build and launch a new inbound-demand vertical that consistently generates 200–300 booked demos per month through organic content, an authoritative newsletter, and automated funnels from free products and automate it with AI, not manual labor or a bloated team.

You are a one-person orchestra.
Strategy, hypotheses, copy, landing pages, sequences, content, analytics — you run it yourself, using AI as your "extra hands" (design, copy, front-end, and research through AI tools, not contractors).

What you'll do

Lifecycle / CRM marketing (core)

• Build and monetize segmented work across the base: newsletter, unsubscribers and cooled-off leads, leads from the sales pipeline, leads from cold outreach. Different segments → different scoring → different sequences.
• Find the signals yourself and turn them into triggered sequences. Example signals: booked a demo but didn't show; read N newsletter issues; used a free product X times; sat in the pipeline for N days. These are examples — your job is to spot such signals and build flows around them.
• Reactivate the "sleeping" base (several thousand leads no longer worth active outreach but recoverable through sequences).

Newsletter as an asset

• Build a genuinely strong, authoritative newsletter — #1 in our space on building and scaling a business / lead gen on Upwork for service companies and freelancers. Not a "mailing list," but a media asset that grows the base and warms it toward demos.

Growth / organic

• Organic growth on LinkedIn and X (Twitter), plus experiments (Reddit, niche content, etc.): viral/value posts that feed funnels.
• Scale a network of established employee accounts (founder-led + team advocates) — not faceless farms, but real personal brands at varying stages that need to be systematized and amplified.
• Funnels from free products: lead magnet → email capture → nurture → auto-purchase of a paid product or a demo.

AI as the way you build it all "by hand"

• Build repeatable marketing systems on AI tools (Cowork, Codex, and similar): a content engine (agents pull data → assemble a content plan → turn it into posts), sequence generation, landing pages, calculators, banners — without pulling in developers or design studios.
• Mine our large internal content library into posts, funnels, and sequences — rather than inventing from scratch.

CRO / web / reputation

• Raise conversion on the site and landing pages (demo page, free-product pages).
• Work on brand reputation: systematic review responses (Trustpilot / G2, etc.), messaging, demo experience.

What we're looking for

We are looking for a marketer who applies AI brilliantly to marketing problems, not a developer placed on marketing.

• 3–5+ years in marketing, specifically in B2B SaaS for the US market.
• A strong foundation in conversion marketing: you crank conversion through meaning — audience pains and desires, purchase triggers, offer structure. That's your base, not just "having seen a lot."
• Proven cases with numbers: you personally wrote converting copy in newsletters/sequences and personally moved landing-page conversion — and can show "before → after."
• Proven volume: you've generated a comparable number of SQLs/demos (in the hundreds per month), not just "ran campaigns."
• Hands-on AI fluency: you already build marketing systems with AI (Cowork / Codex / etc.) and can validate what AI produces, not just publish it blindly.
• Fluent English.
• Ideal background: B2B SaaS in a close space including SalesTech, MarTech, GTM-tech that sold to agencies and service companies. Then you already know our buyer and need no ramp-up on the ICP. Candidates from an agency background aren't a fit; we need a product/SaaS background
• A hard requirement — everything hands-on. The "I assigned tasks to a team/contractors and they did it" profile isn't a fit. We need someone who did it themselves and owned the result.

Our stack

• HubSpot — the core: email, triggers, client documentation.
• AI-first analytics: our agents traverse HubSpot data and return analytics.
• Intercom — behavioral triggers and analytics for active clients.
• Pre-purchase leads — all in HubSpot.

Success metrics (KPIs)

• North star: booked demos per month — ramp to 200–300/month within 3–6 months.
• Newsletter: base growth + end-to-end conversion of the warmed segment to demos (target ~2–3%).
• Demo-page CRO: from a baseline ~2–4% to 6–8%+.
• Free → paid: toward the PLG median of ~9%+.
• Reactivation of the sleeping base: % of leads brought back.

Compensation

• Base: $2,500–3,500/month (depending on level).
• Performance bonus: $1,500–2,500/month at 100% of plan, tied to demos, SQLs, and pipeline contribution; quarterly accelerator for overperformance.
• OTE at 100% of plan: ~$4,000–6,000/month.
• Remote working
• Carrer path to CMO.

What to bring to the call with our team

• Cases with numbers — where you drove growth and which metrics you actually moved (not "the team did it"), including the volume of SQLs/demos generated.
• A live screen-share — show your AI layer (Cowork / Codex / etc.): what you build by hand as a marketer.
• Conversion-marketer thinking — how you crank conversion through audience pains/desires/triggers.

About SpeedSize

SpeedSize powers the next generation of video-led e-commerce. Our patented psychovisual AI and AI-first delivery remove a compromise the industry has lived with for 30 years, speed or quality, so brands can serve full-quality video and imagery at a fraction of the size and load. We work with premium enterprise brands and we're scaling fast.

The role

You'll own the GTM OS: the systems that power our entire go-to-market motion across sales, marketing, partnerships, and the handoffs into finance, operating as one cohesive system fed by clean, structured, real-time data.

You'll transform HubSpot into a ledger for the entire company, deploy a PRM, deploy Sybill, and prepare the OS for AI agents (e.g. Gemini Enterprise). You'll build the reporting the company's divisions run on day to day, and own the data quality that holds it all together.

What you'll own

• HubSpot as the company ledger. Architect and build the object and data model, lifecycle states, pipelines, properties, and workflows so HubSpot becomes the ledger the entire company runs on.
• Context graph (Sybill). Deploy and own the context graph. It auto-populates HubSpot with clean, structured data and gives the entire company a unified, data-driven, customer-centric brain to query.
• Partner system (PRM, e.g. Introw.io). Deploy and own the PRM: data model, deal registration, attribution, partner workflows, and payouts.
• Data architecture, quality, and automation. Own enrichment, routing, scoring, and attribution, and automate lead capture, handoffs, lifecycle, and renewals so teams move without manual setup.
• Integrations and MCP. Connect the stack through APIs and prepare it for MCP access so it's ready for AI agents (e.g. Gemini Enterprise).
• Reporting and forecasting. Build the pipeline, forecasting, and attribution reporting the company's divisions run on day to day, and the data-quality standards that keep it trustworthy.

Who you are

• A GTM systems builder. You build revenue systems that compound. You sit where marketing handoffs meet sales execution and post-sale expansion, and you turn business problems into scalable systems.
• Fluent in HubSpot and the wider GTM stack. You know HubSpot cold as the system of record, and you've worked across CRM, automation, and data tooling to make a stack operate as one.
• AI-native. You think AI-first, you're comfortable with the technology, and you can design a data structure and systems built for the agentic future.
• Outcome-driven. Beyond knowing workflows, you tie every build to the business outcome it drives and ruthlessly prioritize your work against them.
• An owner. You think in outcomes and handoffs, and you run a domain end to end.

Requirements

• Proven experience building and owning GTM systems across sales and marketing
• Deep, hands-on HubSpot expertise as the system of record
• Experience deploying and integrating a PRM and the wider GTM stack
• Workflow automation, data architecture, and data-quality governance (enrichment, routing, scoring, attribution)
• API integration work and data modeling
• Revenue forecasting and pipeline analytics
• Familiarity with Google Workspace and Slack
• Plus: experience with agentic AI, MCP, and context graphs (Sybill)

How we work

You'll work directly with the SVP of Sales & GTM and closely with our CEO and CTO. We move fast, build from first principles, and expect owners.

About the Role

We're a fast-growing HVAC company scaling from $1M to a $2M–$4M annual target. We're looking for an Executive Assistant / Chief of Staff — not a traditional VA — to become the owner's right hand and help build the company's operational backbone. This is a long-term, high-trust role with a clear path to Chief of Staff or Director of Operations.
 

What You'll Own

• Full inbox management: sorting, prioritizing, drafting responses, tracking follow-ups
• Calendar coordination: scheduling, reminders, meeting organization
• Task management: centralized tracking, weekly reporting, workflow organization
• Meeting support: attending, recording, documenting decisions and action items
• Daily/weekly reporting (revenue, open estimates, missed calls, reviews, KPIs)
• Client experience monitoring: reviews, reputation, communication quality
• Contractor coordination: SEO, marketing, suppliers, vendors
• Growth track: eventually training a future Office Manager, building SOPs, overseeing dispatch/CSR quality
   

Who We're Looking For

• Fluent Ukrainian or Russian + English (C1 or higher)
• Higher education degree (business, management, economics, finance, or engineering a plus)
• Prior experience as an EA, Operations Manager, Project Manager, or Chief of Staff preferred
• Strong, hands-on proficiency with AI tools (ChatGPT, Claude, Gemini, etc.)
• Excellent written communication and high organizational standards
• Proactive, systems-thinking mindset — able to solve problems independently and bring recommendations, not just questions
• Comfortable handling confidential information with discretion
• Genuinely seeking a long-term career within one company (this is not a short-term or part-time gig)
   

What Success Looks Like

• 6 months in: Independently running communications, tasks, reports, and meetings; freeing up 15–20+ hours/week of the owner's time
• 12 months in: A true right hand — participating in operational decisions, hiring, and building the company's management system

About the role

No legacy, no bureaucracy, — just you and a small but incredibly strong engineering team making the right technical decisions together. A chance to go deep into fintech (card payments, compliance, settlement) and actually shape the product architecture.
 

Finance focus. This role is for our Finance direction: settlements, reconciliation, bank integrations, and integration with the core banking system. You'll go deep into the money flow — how funds move, settle, and reconcile across gateway, processor, schemes, and banks.
 

Fintech experience is essential. We need someone who already knows payments and fintech — this isn't a domain to pick up on the side. We expect proactivity and a readiness to take on and own the domain expertise: be the person the team relies on for settlement and reconciliation logic.
 

Important: we need a strong engineer with deep technical background. The engineering team is top-tier, and the bar is high. We're not looking for average — we're looking for people who can make decisions independently and own the outcome.
 

What you'll do:
 

Backend (Kotlin)

• Financial Core: double-entry ledger (immutable), settlement engine (MDR calculation, netting, payouts), pricing engine (IC++/blended), rolling reserve management
• Integrations: REST API integrations with payment gateway, card processor, KYC/KYB, SEPA/SWIFT payouts
• Webhook processing: ingestion and processing of vendor webhooks
• BPMN workflows: Camunda 8 — service tasks, user tasks, DMN decision tables for business processes (merchant onboarding, AML investigation, dispute management, settlement)
• Compliance: transaction monitoring rules, sanctions screening integration, SAR workflow
• API: REST API for merchant portal and ops panel
   

Frontend (Next.js)

• Merchant Portal: dashboard (transactions, volumes, conversion), settlement history, payouts, chargebacks, API keys, webhook settings, onboarding wizard
• Ops Panel: case management (AML, disputes), treasury dashboard, compliance dashboard, underwriting, merchant management
• Developer Portal: API documentation (OpenAPI), integration guides, sandbox
   

General

• Reconciliation: multi-layer reconciliation engine (gateway ↔ processor ↔ scheme ↔ bank ↔ safeguarding)
• Reporting: regulatory reporting, scheme reporting (Visa/MC), financial (P&L)
• Testing: we're AI-first when it comes to testing — fully automated coverage at every level: unit, integration, E2E. No manual QA — you write code, you write tests. E2E tests for the full payment flow (auth → capture → settlement → payout), integration tests with vendors, BPMN process tests via Camunda API

Requirements:
 

Must have

• 6+ years of Kotlin or Java (Spring Boot) — REST APIs, JPA/Hibernate, transaction management
• 3+ years of Next.js / React — SSR, TypeScript, state management
• PostgreSQL — queries, migrations, indexes, JSONB
• REST API design — versioning, error handling, idempotency
• Git, CI/CD
• Webhook processing, event-driven architecture
• Okta / OAuth2 / OpenID Connect

Fintech / payments experience — a must, not a nice-to-have: settlements, reconciliation, bank integrations, integration with a core banking system

AI-fluency — active integration of AI tools (Cursor, Claude Code, Codex) into daily engineering work. Not just "aware of AI" — uses it to multiply productivity, with a critical eye for generated output

Proactivity — identifies problems before they surface, proposes solutions, drives them to done. Doesn't wait to be told what to do

English: confident reading and listening is a must. Good spoken English is a strong plus
 

Nice to have:

• Understanding of double-entry accounting
• Camunda / BPMN experience
• Tailwind CSS, shadcn/ui

- Work closely with DevOps and infrastructure teams
 

Video streaming & media (secondary domain knowledge, not a day-one requirement):
- Real-time streaming protocols: SRT, RTMP, MPEG-TS 
- GStreamer and/or FFmpeg exposure; custom GStreamer plugin development is a strong bonus 
- Video encoding/decoding concepts (H.264, H.265, muxing/demuxing)
