Full Stack Developer Hiring Manager Contact, for Every Ad in Your Market
Ad Call reads the live full stack developer ads in your city and hands back, for each company, the person who actually owns the req (the founder or CTO at a startup, the engineering manager at a larger firm) with name, title, email and office line, graded by confidence and flagged with how long the ad has been open.
When an ad lists fourteen technologies, the hiring manager doesn't know which three matter. Your job is to find out.

It depends almost entirely on company size, and the title on the ad won't tell you. At a seed or early-stage startup there is no engineering manager: the technical co-founder or CTO writes the ad, screens the resumes and makes the offer, and that lone leader is the hiring seat, not an escalation. Once a company has several product teams, the req belongs to the engineering manager of the team with the gap. Senior managers and directors approve headcount; talent acquisition runs the process but rarely decides who is good enough.
- Senior Engineer / Tech LeadRuns the technical interview and knows which half of the stack is on fire. Great for intel, not the decision.
- Engineering Manager / Software Engineering Managerusually owns the reqOwns the req at any company with more than one team. This is who decides the front-end/back-end ratio the ad never states.
- Senior Manager, Engineering / Senior Manager, Software EngineeringApproves headcount across several teams. Call when one company is posting three full stack ads at once.
- CTO or technical co-founderAt an early-stage startup this is the hiring manager, full stop. At a large firm, a name to know and not to call about one seat.
What Ad Call gives you for a full stack ad
For full stack ads the result separates the two situations that matter: a small company where the CTO or founder is the only realistic owner, and a larger one where an engineering manager sits between you and the CTO. The signals tell you how long the seat has been empty and whether the company is hiring a team or one person.
Ad CallDeskFollow-upsCompaniesGuide- At a company this size the CTO is still reading every resume; one call reaches the decision.
- Five weeks open on a small team means the CTO is writing production code instead of running the company.
- The technologies the ad repeats (React, Node, Postgres) are the real stack; the rest is wish list.
Full stack means three different jobs: decode which one this ad is
Same title, three different hiring managers, three different pitches. Before you call, place the company in one of these columns.| Early-stage startup | Growth-stage company | Enterprise or large IT shop | |
|---|---|---|---|
| Who owns the req | Founder or CTO, personally | Engineering manager of the team with the gap; CTO still weighs in | Engineering manager; senior manager approves headcount |
| What "full stack" really means | One person ships whole features alone, including deploys and the database | A generalist who leans one way, usually toward the side the team is short on | One side deep, the other side competent enough to not need a handoff |
| The real ratio | Roughly even, plus infrastructure | Ask; expect something like 60/40 or 70/30 one way | Frequently lopsided; the ad rarely says which way |
| What wins the interview | Shipped products end to end, comfort with ambiguity | Depth in the weak side of the team, plus speed | Depth in the primary side, plus the company's framework versions |
| What to ask first | What have you been building yourself that you want to hand off? | Which half of the stack is the team thinnest on? | If this person leans hard to one side, which side? |
Why the ratio is the pitch
Full stack is the single most common way developers describe themselves. In the 2025 Stack Overflow Developer Survey, 27% of respondents picked full-stack developer as the description of their job, almost double the 14.2% who picked back-end. That popularity is the recruiter's problem: every resume in the pile says full stack, so the label proves nothing to the hiring manager.
The BLS Occupational Outlook Handbook draws the line cleanly: back-end developers handle the overall technical construction of a site and make sure it works as expected, while front-end developers create the technical features for its look. A full stack hire is a bet that one person can do both, and every hiring manager secretly expects one side to be stronger. Your candidate is too. So say it out loud: "She's about 70/30 back-end: she owns the API and the database schema, and she's comfortable shipping React screens without a front-end engineer holding her hand." A manager hears that and knows exactly where she fits. "Strong full stack developer" gets you a polite no.
Demand is steady enough that this is worth doing well. BLS projects employment of software developers, quality assurance analysts and testers to grow 10% from 2025 to 2035, with about 106,100 openings a year across the group (BLS: Software Developers).
Full stack developer recruiter tips: find the three technologies that matter
Laundry-list ads are written by committee: the manager's must-haves, the team's current tools, and whatever the last developer used. Sort them before you pitch.- Count repeats. A technology named in both the summary and the requirements is real. One mentioned once at the end of a list usually isn't.
- Separate the core from the plumbing. The language, the front-end framework and the database are the core. Message queues, CI tools and monitoring are learned in a week and rarely decide a hire.
- Read the responsibilities, not the requirements. "Build customer-facing dashboards" is a front-end-heavy seat no matter what the skills list says. "Design data models and integrations" leans back-end.
- Watch for version clues. A specific framework version or a migration ("moving from Angular to React") tells you what the team is living through right now, and what they'll value.
- Check the other open ads. If the company is also posting a front-end or back-end role, the full stack seat is filling whatever gap that other req doesn't cover.
- Ask one question on the call. "If you could only have three of these, which three?" Managers answer it gladly, and the answer is your pitch.
- Match on the three, disclose the rest. Present the candidate on the three that matter, and say plainly which of the other eleven they haven't used. Honesty there buys trust on the core.
Startup full stack developer: who hires, and when to call
At a startup, the hiring manager is also the product manager, the on-call engineer and, often, the person pitching investors. Two things follow.
Funding and growth are timing signals. A company that just announced a round, landed a large customer or launched a product has a hiring plan it has promised to someone. The first engineering ads after that moment are the urgent ones, because the founder is still writing code the new hires were supposed to take over. A second or third engineering ad inside a couple of months is the clearest sign of that push; Ad Call shows how many ads each company has open and how long they've run, so you can see it in the results.
Email beats the phone. Many founders work from a laptop, not a desk, and a startup's listed number often rings an office manager or a shared line. A short, specific email usually gets read the same day; a voicemail may never be heard. Use the office line to confirm who owns the req, then write.
The unicorn objection. When a founder says "we're looking for a unicorn," they usually mean they can't afford two hires. Don't argue. Ask which half would hurt more to be weak on, then offer the candidate who is excellent on that side and credible on the other. That turns an impossible spec into a real search, and it's a conversation the founder rarely gets from recruiters.
The email to a founder or CTO
Short, specific, and built around the ratio. It assumes you already confirmed who owns the req.Your full stack ad lists thirteen tools; React, Node and Postgres show up twice, so I'm guessing those are the three that matter.
I'm working with an engineer who is about 70/30 back-end on exactly that stack. At her last company (a 12-person startup) she built the billing service and its admin screens alone, from schema to deploy, and carried the on-call pager for it.
She hasn't used your queueing tool or your infrastructure-as-code setup. Everything else on the core is a match.
Is that the ratio you want, or do you need someone heavier on the front end? Either answer helps me.
Best,

Questions recruiters ask about full stack developer reqs
- Who is the hiring manager for a full stack developer job?
At an early-stage startup, the founder or CTO. At a company with several engineering teams, the engineering manager of the team the hire joins, with a senior manager approving the headcount. Talent acquisition coordinates but rarely decides.
- What is the best time to contact a full stack developer hiring manager?
Right after a funding announcement, product launch or big customer win, when a hiring plan has been promised; and early in the week, before sprint work fills the calendar. Skip release days. For founders, email in the morning usually beats a phone call at any hour.
- How do I pitch a full stack candidate without sounding generic?
Give the ratio and the proof: "70/30 back-end, built the billing service end to end." Then name the three technologies from the ad that match, and admit the ones that don't.
- Should I call the CTO at a large company about a full stack role?
No. At a company with engineering managers, the CTO doesn't own individual seats. Find the manager of the team in the ad. Save the CTO for a startup, where they are the hiring seat.
