About the company

Hadean is a UK-based defence tech company focused on distributed computing for large-scale simulation, mission rehearsal, and command-and-control style digital environments. The company markets products including dominAI, populAI, and optimAI, and positions the work around AI-enabled, interoperable environments for defence and government customers. Hadean has raised venture funding and has operated across both UK and US defence-facing work. Public materials emphasise high-impact projects and close collaboration across technical and go-to-market teams.

Locations and presence

Hadean lists a London base (Shoreditch area) and also recruits for US-based roles in Washington, DC. Open roles and company profiles point to a UK core with a growing US presence.

Palpable Score

61.2

/ 100

Hadean is better than most startups at showing real internal mobility signals and listing concrete learning support in benefits, which matters for early-career growth. The score is held back by limited, inconsistent entry-level role volume and a lack of published pay ranges that would let graduates judge fairness up front.

Pillar 1: Early-career access

Score

10.2

/ 20

The company publicly invites internship applications and provides a direct route to apply via email, which is a practical entry point.
Hadean has advertised at least one explicitly junior role in recent years (for example, a Junior Software Engineer listing carried on a graduate jobs board), but this is not sustained or frequent in the current public feed.
The company’s own ATS currently shows a small number of open roles and they skew experienced, which limits consistent 0–3 year access.

Pillar 2: Hiring fairness and transparency

Score

13.3

/ 20

The company uses a named ATS (Teamtailor) with structured postings and a consistent application route rather than informal “DM us” hiring.
Hadean includes an adjustments statement for the interview process and explicitly invites candidates to request support, which is a meaningful fairness signal.
The company has mixed candidate sentiment on interview experience in public reviews, which suggests the experience is not consistently predictable across roles.

Pillar 3: Learning and support

Score

14.7

/ 20

The company lists a learning budget (L&D budget) as a role benefit in US hiring, which is one of the clearest “you will be supported” signals.
Hadean positions “Opportunity for Growth” as a benefits theme and ties it to individual learning and development support, not only vague culture language.
The company’s job descriptions are not consistent about onboarding plans, mentoring cadence, or how juniors get feedback week to week, which caps confidence for early-career readers.

Pillar 4: Pay fairness and stability

Score

11.2

/ 20

The company offers stability-oriented benefits that matter early on, including health insurance, enhanced parental leave, flexible working, and extra days off at Christmas (on top of standard leave in the US listing).
Hadean mentions share options in multiple places, which is useful for junior hires if the company explains terms clearly during offer stage.
The company does not consistently publish salary ranges on role pages, so pay fairness can’t be assessed from listings alone and this limits the score.

Pillar 5: Early-career outcomes

Score

11.8

/ 20

The company shares credible internal mobility examples on the careers page, including a People Operations Coordinator moving into a Revenue Operations Manager path and a move from engineering into pre-sales over an 18-month period.
Hadean has generally positive public employee sentiment signals on Glassdoor (overall rating and “would recommend” percentages), but the sample size is modest and not early-career-specific.
The company’s LinkedIn footprint supports that hiring is active across London and Washington, DC, but Hadean does not publish outcome metrics like junior time-to-promotion or retention over 12–24 months.
