Inženir za implementacijo in integracije (m/ž) @ VIAR d.o.o.

VIAR d.o.o. — Tue, 01 Sep 2026 20:29:04 +0200

Prav zdaj nekje v Evropi farmacevtski tehnik po navodilu v REWO nastavlja stroj, ki izdeluje zdravila. Nekje drugje nekdo sestavlja komponento, ki bo naslednji mesec vgrajena v avtomobil na avtocesti. Vse to s pomočjo platforme REWO.

REWO je naša SaaS platforma za proizvodnjo — vizualna delovna navodila, digitalni SOP-i, usposabljanja in zapisi o skladnosti. Uporabljajo ga Krka, Coloplast, Stora Enso, Henkel, Mann+Hummel, Hella in drugi. Po svetu podpira že več kot 500.000 zaposlenih. Nekateri REWO poganjajo v našem oblaku, mnogi v zasebnem oblaku ali v celoti lokalno (on-premise).

Iščemo inženirja, ki bo prevzel odgovornost za to, kako se REWO namesti, integrira in ohranja v delovanju — in ki bo tehnični sogovornik IT oddelkom naših strank. Približno pol dela je infrastruktura in nameščanje, pol implementacija pri strankah, integracije in tehnična komunikacija. Začeli boste z rednimi namestitvami v oblaku in internim DevOps delom, od tam pa prešli na zasebni oblak in lokalna okolja strank. Nihče prvi teden ne dobi v roke produkcijskega strežnika stranke.

VAŠE DELO BO OBSEGALO
-> Nameščanje in nadgrajevanje REWO v oblaku, zasebnem oblaku in lokalnih okoljih
-> Spremljanje strežnikov, varnostnih kopij in certifikatov
-> Sodelovanje z IT ekipami strank: požarne pregrade, VPN, povezljivost
-> Nastavljanje in odpravljanje težav pri integracijah z MES in ERP sistemi (HTTP API-ji, avtentikacija, webhooki)
-> Nastavljanje SSO in upravljanja uporabnikov proti identitetnim sistemom strank
-> Odgovarjanje na vprašanja IT oddelkov strank o infrastrukturi, arhitekturi in varnosti

To ne pomeni življenja po sestankih — nekaj kratkih tehničnih klicev na teden. Ko pa do njih pride, potrebujemo nekoga, ki zna reči "Tega še ne vem. Preverim in se javim." in nato res poskrbi za nadaljevanje. In pa brez skrbi, ne boste sami. Trenutno to upravlja eden od vaših bodočih sodelavcev, a rabi zaradi povečanega obsega dela pomoč!

We’re building something that doesn’t exist yet: an AI immune system for humans.The Umanitek Guardian Agent protects people from deepfakes and digital impersonation by combining intelligence with systems built for verification and scale. If you’re excited by the idea of building reliable platforms and backend systems for agents that reason, not just predict, you’ll feel right at home.

Success means faster, safer releases and fewer reactive security escalations.

What will you do?

As a Senior Security Engineer, your mission will be to:

Partner with developers to embed security into design, build, and deploy stages
Automate vulnerability triage and mitigation flows
Secure CI/CD pipelines (GitHub, Jenkins) and execution environments (Kubernetes, Docker)
Tune WAFs, manage cloud security (AWS, GCP, Azure), and evolve Terraform practices
