Character Concepts:

Since we're a Barbarian already, we don't need to meet the STR requirements

Ancestry: Hobgoblin (Smokeworker) or Hobgoblin (Ifrit) Background: Field Medic is practically required, we need access to Battle Medicine as a free feat so Godless Healing is available at level 2.

Ifrit/Incediary Aura: https://www.reddit.com/r/Pathfinder2e/comments/s30xex/flames_oracle_clarification/

Level 5 Ancestry Feat: Runtsage (Burn It!)

Is it even that good? It's spells and alchemical items, not all sources of damage. Turning xd4 into xd4+1 seems bad.

The Bard's Dirge of Doom with the Hobgoblin's Agonizing Rebuke (level 5 Ancestry Feat). Are there other ways to keep an enemy Frightened?

Ancestry Feats:

Free Archetype: Oracle

Free Archetype: Oracle Dedication (Flames)

Unfortunately, we get Religion and Acrobatics from the Oracle Dedication. As far as the curse, we aren't planning on targeting anything outside of melee range anyways.

Skill Feats

Is Mortal Healing Better?

Assurance doesn't get us anything before level 3.

Weapons

Breaching Pike? Guisarme?

Dedications

Oracle Dedication (Flames)

This character is built around the Flames Mystery.

The Spellcasting feat feels like a bit of a waste but it enables Staves for us (we can pick up a Staff of Healing around the same level). The level 1 Divine Spells are okay and given the type of character we are, Spirit Link is an interesting choice; Spirit Weapon is another option but you get access to Striking Runes at the same time you can cast it.

Medic Dedication

We can't really justify delaying the Oracle Dedication until level 6 unless you can convince your GM to remove the special three feat rule from it (most GMs should remove the special rule from the first dedication you take).

Level Progression

Level 1:

Level 2:

For Godless Healing, you benefit from the bonus hit points regardless if you take the action or not and since Battle Medicine and Treat Wounds are different actions you can benefit from both actions once per hour now.

FAQ

How does Fire Resistance compare between Dragon Instinct and Smokeworker?

Here's a table for this particular build, it is possible to have a higher CON modifier with other stat distributions but this is likely the most common anyways. An asterisks (*) denotes levels where the CON modifier differs if you started with 16 CON.

Level CON Modifier Smokeworker Dragon Instinct
1 +2 1 -
2 +2 1 -
3 +2 1 -
4 +2 2 -
5 +3 2 -
6 +3 3 -
7 +3 3 -
8 +3 4 -
9 +3 4 6*
10 +4 5 7
11 +4 5 7
12 +4 6 7
13 +4 6 7
14 +4 7 7
15 +4 7 7*
16 +4 8 7*
17 +4 8 7*
18 +4 9 7*
19 +4 9 7*
20 +5 10 8

Notes: Dragon Instinct's Resistances only apply when Raging, and you cannot Rage Unconscious (as in, while Dying). Smokeworker applies all the time. This table can be used for any heritage that provides an elemental damage resistance as the formula is the same across heritages.

Basically, Smokeworker will match or outperform Dragon Instinct from levels 1-8 and again from levels 14-20. This means there's only a small window of 9-14 where Dragon Instinct is conditionally better (along with level 15 if CON was maxed).

The takeaway here is that the resistance bonus from Smokeworker is a really good source of Resistance.

How does Resistance work?

https://2e.aonprd.com/Rules.aspx?ID=346

Resistance does not stack, the highest value is always used instead.

How does Persistent Damage work?

Persistent Damage occurs at the end of each of your turns as long as you have the condition (rolling the damage dice each time). When you take Persistent Damage, roll a flat DC 15 check to see if the condition ends. Persistent Damage generally lasts one minute but it's determined by the GM.

Persistent Damage does not stack but the higher damage value applies. It only triggers once each turn but all applicable damage types occur from that trigger; this means a dying creature may take multiple types of damage from Persistent Damage but their Dying condition only increases once.

How does Burn It! Interact with Focus Spells?

Focus Spells are heightened to half of your character level. Burn It! applies a status bonus equal to half of the spell's level, so it's safe to assume the status bonus would be 1/2 level, then 1/2 of that level, rounded down each time.

Since this build focuses on Incendiary Aura, a spell that doesn't actually do damage, the only bonus you get from Burn It! is the +1 status bonus to any persistent fire damage you deal.

Can you benefit from both Treat Wounds and Battle Medicine?

Yes, they stack and are on separate timers.
