Make a career planI’ve been a senior engineer for 3 years. Should I push for Staff or move into management?
That’s the right question to ask at this stage.
Let’s compare both paths: compensation, day-to-day work, and long-term fit.
First, what energised you more this year: technical problem-solving or people leadership?
Salary Negotiation Coaching
Jack helps you build a negotiation plan with data and specific language you can use. Know when to push, what to ask for, and how to respond without damaging the relationship.

“A solid 5 stars for this genius technology that made me feel like I was actually being supported and cared for. I have actually landed my dream role thanks to Jack. I’m still chatting with Jack to find little gigs here and there.”
Yasmine A.
“It’s a league above most recruiters, simply in remembering details and not having an agenda of its own that can leave you in a compromised position like many recruiters do. The Jack and Jill pairing dynamic works really well. Highly recommended.”
Gareth L.
“Feels like having a real talent partner 24/7, not a job board. Jack takes the time to understand your background, preferences, and long-term goals, then filters opportunities accordingly. The matches feel thoughtful rather than volume-driven.”

Your Plan
Companies pay when they hire through Jill.
Why is Jack free?
Jack’s mission is to give everyone unimaginably good career support, not just those who’ve already made it. When Jack introduces you to a company through Jill’s network and you get hired, the company pays a fee. Career coaching normally costs $300/hour. Jack gives everyone the same support for free. No catch. No hidden fees. Completely free.
“Got a direct intro to the CEO through Jack. Skipped the entire application process. Hired in two weeks. This is genuinely how hiring should work.”
