Senior NDT Engineer (NDE Level III)

How do you inspect a reactor component through liquid lead, a coolant you cannot see through? No standard procedure exists for it

yet, and none will until someone works out how ultrasound behaves in lead and builds a method around it. We are looking for a

Level III in UT who wants to work this out together with us.

You start the development and shape the technical roadmap with the team: what to investigate, with which techniques (PAUT, TOFD,

TFM, EMAT and related), and in what order. You work on our test rigs and with partners, turn the data into better methods, and

build the technical basis for the procedures and acceptance criteria. With your Level III competence in UT, you also support and

guide the Level II technicians who will apply them. You are our main technical contact towards UT suppliers, and you collaborate

with welding, materials, design and quality so that components are inspectable by design.

Blykalla is developing the next generation of nuclear technology with our Small Modular Reactor (SMR) based on innovative fuel,

materials, and reactor designs. As Sweden’s only SMR developer, we are on a mission to decarbonize industries and enable safe,

scalable, and sustainable energy solutions. Our technology uses uranium nitride fuel and lead coolant, creating novel challenges

and opportunities for the fuel cycle and supporting systems.

As Senior NDT R&D Engineer, you connect the method, the data and the evidence that it works. You help shape what gets developed

and in which order, work with our team and partners on the test rigs, and make sure each method is validated before it goes into

use. Your responsibilities will include:

• Shape and maintain the UT method roadmap for NDE and In-Service Inspection together with the team, focused on through-lead

acoustics: what is developed, in which order, and to what maturity.

• Develop and adapt UT techniques (PAUT, TOFD, TFM, EMAT and others) to our geometries, materials and operating conditions,

working from first principles where needed.

• Plan and run trials, mock-ups and reference samples on components, welds and base materials, on our test rigs or with partners,

and join hands-on where a method needs it.

• Interpret signals, characterise defects, and use signal processing and frequency-domain analysis to improve probe setup,

calibration, procedures and sensitivity.

• Be our main technical contact for UT suppliers: screen and test their solutions, share findings, and give the technical

decision and recommendation for selection.

• Work together with research institutes, universities and our welding, materials, design and quality teams, so that components

are inspectable by design.

You will help shape how SEALER components are inspected, from the first test rig to fleet deployment. As the NDE and In-Service

Inspection area grows, the role grows with it: into Responsible Level III for NDE and In-Service Inspection, with dedicated NDT

R&D engineers joining the team to build the methods further together with you.

You are a curious, thoughtful engineer who enjoys turning an inspection problem into a method, and a method into data the team can

trust. You bring technical depth, practical UT experience and a structured way of working, and you are not afraid to ask a

supplier the critical question and check the answer against the data.

• ISO 9712 Level 3 in UT (or equivalent, for example SNT-TC-1A Level III), with experience maintaining a written practice and

guiding Level II technicians.

• Practical UT experience in a regulated industry (aerospace, oil & gas, nuclear, power generation or pressure equipment),

including at least one advanced technique (PAUT, TOFD, TFM or EMAT), and familiarity with ASME, ISO and industry NDT codes.

• Experience in method development or inspection R&D, and the curiosity to work out a method from first principles when no

standard procedure applies.
